An adoptive transfer of selected native or engineered immune effector cells represents a promising approach to efficiently treat tumors, such as infiltrative brain cancers, taking care of limiting reactivities against non-transformed cells15,16,17,18. However, the central nervous system, which comprises the brain, has a particular immune status, notably due to the existence of the blood-brain b...

GBM (WHO grade IV astrocytoma), is the most frequent and aggressive primary brain cancer in adults. In spite of aggressive treatments that combine surgery and radio-chemotherapy, GBM remains associated with an extremely poor prognosis (median survival of 14.6 months and a 2-year-mortality &#62; 73%)1. This evidences that few efficient therapeutic advances have been validated over the last decade2. Among candidates for the design of more effective therapeutic strategies3,4,5, immunotherapies6 are currently explored to track and eliminate highly invasive and radio/chemo-resistant tumor cells, suspected for their key contribution to rapid and fatal tumor relapse7. Various potential immunological targets were identified and proposed for immunotherapies, involving natural or modified &#945;&#946; or &#978;&#948; T lymphocytes such as GBM-specific tumor antigens or stress-induced molecules8,9,10. The possibility to administrate selected GBM-reactive immune cell effectors represents a unique opportunity to deliver elevated amounts of effector lymphocytes directly into the site of residual malignancy. To support this strategy, we have recently shown that models based on immunodeficient mice carrying orthotopic primary human GBM xenografts faithfully recapitulate the development of brain tumors in GBM patients9,11. Moreover, these models were used to demonstrate the strong antitumor efficiency of adoptively transferred allogeneic human V&#978;9V&#948;2T lymphocytes.
This protocol describes the critical experimental steps for achieving stereotactic immunotherapies of brain tumors, such as GBM, based on the adoptive transfer of allogeneic T lymphocytes. The article shows: (i) the amplification of therapeutic allogeneic immune effector T lymphocytes, such as human V&#978;9V&#948;2T lymphocytes; (ii) the preparation of these effector T lymphocytes for injection; (iii) the procedure for stereotactic administration within the brain, near the tumor. This article also provides insight into the behavior of these cellular effectors after stereotactic injection.
The therapeutic approach presented here is based on the injection of 20 x 106 effector cells per dose for each brain tumor-bearing immunodeficient mouse. An initial in vitro expansion step is required to produce large quantities of immune cells. Therefore, non-specific cell expansions are performed using phytohemagglutinin (PHA-L) and irradiated allogeneic feeder cells: peripheral-blood mononuclear cells (PBMCs) from healthy donors and Epstein Barr Virus (EBV)-transformed B-lymphoblastoid cell lines (BLCLs), derived from PBMCs by in vitro infection with EBV-containing culture supernatant from the Marmoset B95-8 cell line, in the presence of 1 &#181;g/mL cyclosporin-A.
GBM-reactive effector immune cells are compared and selected from in vitro assays9. These effector cells are activated and amplified using standard protocols, according to their nature (e.g., human V&#947;9V&#948;2 T lymphocytes9 or human anti-herpes virus &#945;&#946; T lymphocytes12) with a minimum purity of &#62; 80%, as routinely checked by cytometric analysis. The cell expansion procedure detailed below applies to various human lymphocyte subsets.

stereotactic adoptive transfer of cytotoxic immune cells in murine models of orthotopic human glioblastoma multiforme xenografts

Glioblastoma multiforme (GBM), the most frequent and aggressive primary brain cancer in adults, is generally associated with a poor prognosis, and scarce efficient therapies have been proposed over the last decade. Among the promising candidates for designing novel therapeutic strategies, cellular immunotherapies have been targeted to eliminate highly invasive and chemo-radioresistant tumor cells, likely involved in a rapid and fatal relapse of this cancer. Thus, administration(s) of allogeneic GBM-reactive immune cell effectors, such as human V&#978;9V&#948;2 T lymphocytes, in the vicinity of the tumor would represents a unique opportunity to deliver efficient and highly concentrated therapeutic agents directly into the site of brain malignancies. Here, we present a protocol for the preparation and the stereotaxic administration of allogeneic human lymphocytes in immunodeficient mice carrying orthotopic human primary brain tumors. This study provides a preclinical proof-of-concept for both the feasibility and the antitumor efficacy of these cellular immunotherapies that rely on stereotactic injections of allogeneic human lymphocytes within intrabrain tumor beds.

This study describes the strategy of adoptive transfers of cellular immune effector cells within the brain of tumor-carrying mice, based on stereotactic injections performed directly within the tumor bed.
To minimize any risk of brain injury associated with a large injection volume, the effector cell suspension needs to be concentrated (20 x 106 cells in 15 - 20 &#181;L of PBS). To check whether this cell concentratio...

Glioblastoma multiforme remains the most frequent and aggressive primary brain tumor in adults. Despite aggressive treatments based on surgery followed by radio and chemotherapy, GBM is associated with an extremely poor prognosis and a median survival lower than 15 months. Since few therapeutic advances have been made over the last decade, cellular immunotherapies are currently explored to eliminate highly-invasive and resistant GBM cells likely involved in rapid tumor relapse.administrations of selected GBM-reactive cytotoxic immuno factors in the vicinity of the tumor could represent a unique opportunity to deliver concentrated cellular immunotherapy, directly into the site of residual malignancy. Our group recently showed that immunodeficient NSG mice carrying orthotopic primary human GBM xenograft recapitulate GBM to more development in patients. These GBM models were used to evaluate the efficacy of cytotoxic immune effectors on intratumoral injections.This protocol describes our therapeutical process based on first the isolation and amplification of GBM-reactive immune effector cells. Second, the propagation of these effector cells for intercranial injection. And third, their stereotactic injection at the tumor site within the mouse brain.The behavior of the immune effector after orthotopic injection was also investigated. Three weeks after PHA fetus stimulation, effector cells, which form cell clump in the bottom of the flask should have returned to rest state and are ready to be used. After checking effector cell count, resuspend and collect cells in 115 milliliters tube and centrifuge them.Carefully and completely remove a supernatant. And resuspend cells in sterile PBS and centrifuge to wash them. Carefully and completely take off the supernatant.And then resuspend cells in one milliliter of sterile PBS. Transfer cells in a microtube for centrifugation. Again, carefully and completely take off the supernatant by pipetting slowly.The next step is critical, resuspend cells in half of the final volume of sterile PBS and homogenize softly and carefully. Verify the final volume with micropipette, final volume per mouse has to be between 15 and 20 microliter for 20 million cells. Be sure it will not exceed 20 microliter per mouse.Keep cells on ice until injection. Ensure that the animal is adequately anesthetized by a toe pinch and then remove fur from the surgical site, between the two ears and up to the nose. Resuspend cells slowly to prevent cell clumping and load cell suspension into syringe with great care to avoid the presence of bubbles.Then, place the syringe into the adapted syringe pump. Disinfect the surgical site with salt and povidone iodine 5%solution and place a lubricating ophthalmic ointment in the mouse's eyes to prevent drying of the cornea. Then, position the anesthetized mouse on the stereotactic frame on a warm block.Appropriately position mouse's nose and teeth above the tooth bar. Tighten ear bars firmly in the mouse ears to immobilize the head. Be careful not to damage the eardrums, compromise the respiration, and make sure that head is well immobilized.Make a midline sagittal skin incision with sterile scissors along the upper part of the cranium to expose the skull. Identify the intersection of the sagittal and coronal structures to serve as landmarks for stereotactic localization, and place the syringe above this point. Move the syringe at predetermined coordinates.Two millimeter right lateral, and 0.5 millimeter anterior of the Using a microdrill, make a small hole in the skull with sterile drill bit. Be careful to remain superficial in order to avoid brain injury. Insert syringe carefully into the drilled hole.Move slowly forward the needle three millimeter down in the dura, and then backward 0.5 millimeter to a final depth of 2.5 millimeter cells injection. Run the cell injection at two or three microliter per minute, and monitor the mice all along the injection time. Once injection is complete, withdraw the needle for only one millimeter and keep syringe in place for an additional minute before slowly withdrawing completely the syringe to prevent any leakage from the infusion site.Remove carefully the animal from the stereotactic frame. Close skin with appropriate surgical suture and apply 2%Lidocaine gel directly on the wound. Transfer anesthetized mouse to its respective cage above heating pad set to 37 degrees Celsius to maintain appropriate mouse body temperature until full recovery from anesthesia.As the suspension is very concentrated, the cell viability and reactivity were checked. Effector cells were loaded in syringe in order to mimic in vivo injection. Cells were collected immediately or 10 minutes later and were analyzed by flow cytometry for propidium iodide staining.As you can see, the preparation and the loading did not affect the viability of effector cells at 24 hours. The reactivity against Glioblastoma tumor cells were also checked using either unprepared cells or effectors prepared and stayed three hours on the eyes. Reactivity is monitored by positive staining of the activation marker CD107A.These results demonstrate that the effector cells'reactivity were not affected by the preparation. Seven days after effector cells'injection, mice brains were collected, sectioned, and stained for hematic coloration to allow the identification of tumor structure. Then anti-human CD3 staining allowed localization of effector cells.Interestingly, effector cells were found around the tumor and in the tumor core, but also in contralateral hemisphere. Human effector T-cells isolated from mouse brain 48 hours after the injection represent 2%of brain cells. They were still able to proliferate in presence of PHA, feeders and IL2 stimulation, with a 99%purity after amplification.Thanks to this protocol, resting human effector cells can survive and patrol with a mouse brain parenchyma for several days following the stereotaxic injection. In conclusion, adoptive transfer of human effector cells by stereotactic injections represent promising approaches to efficiently treat infiltrative malignant brain tumors with limited deleterious effects on healthy cells. This route of administration takes advantage that human cells are delivered closely to the tumor site, limiting their dilution within the tissues and the organism.Here we described the procedure following the delivering of a large amount of immune cells within the brain tumor without harmful effects on effector cells and, importantly, without any visible deleterious effect on mice. Moreover, locally-injected immune cells in mouse brain are not only able to survive and keep their ability to be activated and amplified ex vivo, but also to and eliminate disseminated tumor cells in the surrounding brain tissue. Collectively, these features are essential to allow the elimination of strong infiltrative tumor cells that characterize GBM tumors.This protocol opens new opportunity for the establishment of adoptive transfer procedure in mice model of brain tumor. Essential step before considering clinical CD.

Experimental Metastasis and CTL Adoptive Transfer Immunotherapy Mouse Model

Experimental metastasis mouse model is a simple and yet physiologically relevant metastasis model. The tumor cells are injected intravenously (i.v) into mouse tail veins and colonize in the lungs, thereby, resembling the last steps of tumor cell spontaneous metastasis: survival in the circulation, extravasation and colonization in the distal organs. From a therapeutic point of view, the experimental metastasis model is the simplest and ideal model since the target of therapies is often the end point of metastasis: established metastatic tumor in the distal organ. In this model, tumor cells are injected i.v into mouse tail veins and allowed to colonize and grow in the lungs. Tumor-specific CTLs are then injected i.v into the metastases-bearing mouse. The number and size of the lung metastases can be controlled by the number of tumor cells to be injected and the time of tumor growth. Therefore, various stages of metastasis, from minimal metastasis to extensive metastasis, can be modeled. Lung metastases are analyzed by inflation with ink, thus allowing easier visual observation and quantification.

Seven Steps to Stellate Cells

Hepatic stellate cells are liver-resident cells of star-like morphology and are located in the space of Disse between liver sinusoidal endothelial cells and hepatocytes1,2. Stellate cells are derived from bone marrow precursors and store up to 80% of the total body vitamin A1, 2. Upon activation, stellate cells differentiate into myofibroblasts to produce extracellular matrix, thus contributing to liver fibrosis3. Based on their ability to contract, myofibroblastic stellate cells can regulate the vascular tone associated with portal hypertension4. Recently, we demonstrated that hepatic stellate cells are potent antigen presenting cells and can activate NKT cells as well as conventional T lymphocytes5. 

 Here we present a method for the efficient preparation of hepatic stellate cells from mouse liver. Due to their perisinusoidal localization, the isolation of hepatic stellate cells is a multi-step process. In order to render stellate cells accessible to isolation from the space of Disse, mouse livers are perfused in situ with the digestive enzymes Pronase E and Collagenase P. Following perfusion, the liver tissue is subjected to additional enzymatic treatment with Pronase E and Collagenase P in vitro. Subsequently, the method takes advantage of the massive amount of vitamin A-storing lipid droplets in hepatic stellate cells. This feature allows the separation of stellate cells from other hepatic cell types by centrifugation on an 8% Nycodenz gradient. The protocol described here yields a highly pure and homogenous population of stellate cells. Purity of preparations can be assessed by staining for the marker molecule glial fibrillary acidic protein (GFAP), prior to analysis by fluorescence microscopy or flow cytometry. Further, light microscopy reveals the unique appearance of star-shaped hepatic stellate cells that harbor high amounts of lipid droplets. 


 Taken together, we present a detailed protocol for the efficient isolation of hepatic stellate cells, including representative images of their morphological appearance and GFAP expression that help to define the stellate cell entity.

Here we describe a method for the isolation of hepatic stellate cells from mouse liver. For stellate cell purification, mouse livers are digested in situ and in vitro by pronase-collagenase treatment prior to density gradient centrifugation. This technique yields highly pure hepatic stellate cells.

Flow Cytometry Analysis of Immune Cells Within Murine Aortas

Atherosclerosis is a chronic inflammatory process of medium and large size vessels that is characterized by the formation of plaques consisting of foam cells, immune cells, vascular endothelial and smooth muscle cells, platelets, extracellular matrix, and a lipid-rich core with extensive necrosis and fibrosis of surrounding tissues.1 The innate and adaptive arms of the immune response are involved in the initiation, development and persistence of atherosclerosis.2, 3 There is a significant body of evidence that different subsets of the immune cells, such as macrophages, dendritic cells, T and B lymphocytes, are present within the aortas of healthy and atherosclerosis-prone mice4. Additionally, immune cells are found in the surrounding aortic adventitia which suggests an important role of this tissue in atherogenesis.2
For some time, the quantitative detection of different types of immune cells, their activation status, and the cellular composition within the aortic wall was limited by RT-PCR and immunohistochemical methods for the study of atherosclerosis. Few attempts were made to perform flow cytometry using human aortas, and a number of problems, such as a high autofluorescence, have been reported5,6. Human atherosclerotic plaques were digested with collagenase 1, and free cells were collected and stained for CD14+/CD11c+ to highlight macrophage-derived foam cells. In this study, a "mock" channel was used to avoid false-positive staining.6 Necrotic materials accumulating during the digestion process give rise in a large amount of debris that generates a high autofluorescence in aortic samples. To resolve this problem, a panel of negative and positive controls has been proposed, but only double staining could be applied in these samples. We have developed a new flow cytometry-based method7 to analyze the immune cell composition and characterize the activation, proliferation, differentiation of immune cells in healthy and atherosclerosis-prone aorta. This method allows the investigation of the immune cell composition of the aortic wall and opens possibilities to use a broad spectrum of immunological methods for investigations of immune aspects of this disease.

This paper presents a flow cytometry-based method to investigate the immune composition of aortas. The paper also illustrates an additional technique that allows examining surrounding adventitia and vessel wall separately. This method opens possibilities to perform phenotypical analyses of aortic leukocytes and apply several immunological assays for atherosclerosis studies.

Overcoming Unresponsiveness in Experimental Autoimmune Encephalomyelitis (EAE) Resistant Mouse Strains by Adoptive Transfer and Antigenic Challenge

Experimental autoimmune encephalomyelitis (EAE) is an inflammatory disease of the central nervous system (CNS) and has been used as an animal model for study of the human demyelinating disease, multiple sclerosis (MS). EAE is characterized by pathologic infiltration of mononuclear cells into the CNS and by clinical manifestation of paralytic disease. Similar to MS, EAE is also under genetic control in that certain mouse strains are susceptible to disease induction while others are resistant. Typically, C57BL/6 (H-2b) mice immunized with myelin basic protein (MBP) fail to develop paralytic signs. This unresponsiveness is certainly not due to defects in antigen processing or antigen presentation of MBP, as an experimental protocol described here had been used to induce severe EAE in C57BL/6 mice as well as other reputed resistant mouse strains. In addition, encephalitogenic T cell clones from C57BL/6 and Balb/c mice reactive to MBP had been successfully isolated and propagated.
The experimental protocol involves using a cellular adoptive transfer system in which MBP-primed (200 &mu;g/mouse) C57BL/6 donor lymph node cells are isolated and cultured for five days with the antigen to expand the pool of MBP-specific T cells. At the end of the culture period, 50 million viable cells are transferred into naive syngeneic recipients through the tail vein. Recipient mice so treated normally do not develop EAE, thus reaffirming their resistant status, and they can remain normal indefinitely. Ten days post cell transfer, recipient mice are challenged with complete Freund adjuvant (CFA)-emulsified MBP in four sites in the flanks. Severe EAE starts to develop in these mice ten to fourteen days after challenge. Results showed that the induction of disease was antigenic specific as challenge with irrelevant antigens did not induce clinical signs of disease. Significantly, a titration of the antigen dose used to challenge the recipient mice showed that it could be as low as 5 &mu;g/mouse. In addition, a kinetic study of the timing of antigenic challenge showed that challenge to induce disease was effective as early as 5 days post antigenic challenge and as long as over 445 days post antigenic challenge. These data strongly point toward the involvement of a "long-lived" T cell population in maintaining unresponsiveness. The involvement of regulatory T cells (Tregs) in this system is not defined.

Certain mouse strains are able to resist induction of experimental autoimmune encephalomyelitis (EAE) with myelin basic protein. Described here is a simple immunization protocol that reverses the unresponsiveness and induces paralytic disease in several typical EAE resistant mouse stains.

Accelerated Type 1 Diabetes Induction in Mice by Adoptive Transfer of Diabetogenic CD4+ T Cells

The nonobese diabetic (NOD) mouse spontaneously develops autoimmune diabetes after 12 weeks of age and is the most extensively studied animal model of human Type 1 diabetes (T1D). Cell transfer studies in irradiated recipient mice have established that T cells are pivotal in T1D pathogenesis in this model. We describe herein a simple method to rapidly induce T1D by adoptive transfer of purified, primary CD4+ T cells from pre-diabetic NOD mice transgenic for the islet-specific T cell receptor (TCR) BDC2.5 into NOD.SCID recipient mice. The major advantages of this technique are that isolation and adoptive transfer of diabetogenic T cells can be completed within the same day, irradiation of the recipients is not required, and a high incidence of T1D is elicited within 2 weeks after T cell transfer. Thus, studies of pathogenesis and therapeutic interventions in T1D can proceed at a faster rate than with methods that rely on heterogenous T cell populations or clones derived from diabetic NOD mice.

We provide a reproducible method to induce type 1 diabetes (T1D) in mice within two weeks by the adoptive transfer of islet antigen-specific, primary CD4+ T cells.

Assessing the Development of Murine Plasmacytoid Dendritic Cells in Peyer's Patches Using Adoptive Transfer of Hematopoietic Progenitors

This protocol details a method to analyze the ability of purified hematopoietic progenitors to generate plasmacytoid dendritic cells (pDC) in intestinal Peyer&#39;s patch (PP). Common dendritic cell progenitors (CDPs, lin- c-kitlo CD115+ Flt3+) were purified from the bone marrow of C57BL6 mice by FACS and transferred to recipient mice that lack a significant pDC population in PP; in this case, Ifnar-/- mice were used as the transfer recipients. In some mice, overexpression of the dendritic cell growth factor Flt3 ligand (Flt3L) was enforced prior to adoptive transfer of CDPs, using hydrodynamic gene transfer (HGT) of Flt3L-encoding plasmid. Flt3L overexpression expands DC populations originating from transferred (or endogenous) hematopoietic progenitors. At 7-10 days after progenitor transfer, pDCs that arise from the adoptively transferred progenitors were distinguished from recipient cells on the basis of CD45 marker expression, with pDCs from transferred CDPs being CD45.1+ and recipients being CD45.2+. The ability of transferred CDPs to contribute to the pDC population in PP and to respond to Flt3L was evaluated by flow cytometry of PP single cell suspensions from recipient mice. This method may be used to test whether other progenitor populations are capable of generating PP pDCs. In addition, this approach could be used to examine the role of factors that are predicted to affect pDC development in PP, by transferring progenitor subsets with an appropriate knockdown, knockout or overexpression of the putative developmental factor and/or by manipulating circulating cytokines via HGT. This method may also allow analysis of how PP pDCs affect the frequency or function of other immune subsets in PPs. A unique feature of this method is the use of Ifnar-/- mice, which show severely depleted PP pDCs relative to wild type animals, thus allowing reconstitution of PP pDCs in the absence of confounding effects from lethal irradiation.

This protocol describes experimental procedures to assess the differentiation of plasmacytoid dendritic cells in Peyer&#8217;s patch from common dendritic cell progenitors, using techniques involving FACS-mediated cell isolation, hydrodynamic gene transfer, and flow analysis of immune subsets in Peyer&#8217;s patch.

Generation of CAR T Cells for Adoptive Therapy in the Context of Glioblastoma Standard of Care

Adoptive T cell immunotherapy offers a promising strategy for specifically targeting and eliminating malignant gliomas. T cells can be engineered ex vivo to express chimeric antigen receptors specific for glioma antigens (CAR T cells). The expansion and function of adoptively transferred CAR T cells can be potentiated by the lymphodepletive and tumoricidal effects of standard of care chemotherapy and radiotherapy. We describe a method for generating CAR T cells targeting EGFRvIII, a glioma-specific antigen, and evaluating their efficacy when combined with a murine model of glioblastoma standard of care. T cells are engineered by transduction with a retroviral vector containing the anti-EGFRvIII CAR gene. Tumor-bearing animals are subjected to host conditioning by a course of temozolomide and whole brain irradiation at dose regimens designed to model clinical standard of care. CAR T cells are then delivered intravenously to primed hosts. This method can be used to evaluate the antitumor efficacy of CAR T cells in the context of standard of care.

The lymphodepletive and immunomodulatory effects of chemotherapy and radiation standard of care can be leveraged to enhance the antitumor efficacy of T cell immunotherapy. We outline a method for generating EGFRvIII-specific chimeric antigen receptor (CAR) T cells and administering them in the context of glioblastoma standard of care.

Induction of Murine Intestinal Inflammation by Adoptive Transfer of Effector CD4+CD45RBhigh T Cells into Immunodeficient Mice

There are many different animal models available for studying the pathogenesis of human inflammatory bowel diseases (IBD), each with its own advantages and disadvantages. We describe here an experimental colitis model that is initiated by adoptive transfer of syngeneic splenic CD4+CD45RBhigh T cells into T and B cell deficient recipient mice. The CD4+CD45RBhigh T cell population that largely consists of na&#239;ve effector cells is capable of inducing chronic intestinal inflammation, closely resembling key aspects of human IBD. This method can be manipulated to study aspects of disease onset and progression. Additionally it can be used to study the function of innate, adaptive, and regulatory immune cell populations, and the role of environmental exposures, i.e., the microbiota, in intestinal inflammation. In this article we illustrate the methodology for inducing colitis with a step-by-step protocol. This includes a video demonstration of key technical aspects required to successfully develop this murine model of experimental colitis for research purposes.

Assessment of the Cytotoxic and Immunomodulatory Effects of Substances in Human Precision-cut Lung Slices

Respiratory diseases in their broad diversity need appropriate model systems to understand the underlying mechanisms and enable development of new therapeutics. Additionally, registration of new substances requires appropriate risk assessment with adequate testing systems to avoid the risk of individuals being harmed, for example, in the working environment. Such risk assessments are usually conducted in animal studies. In view of the 3Rs principle and public skepticism against animal experiments, human alternative methods, such as precision-cut lung slices (PCLS), have been evolving. The present paper describes the ex vivo technique of human PCLS to study the immunomodulatory potential of low-molecular-weight substances, such as ammonium hexachloroplatinate (HClPt). Measured endpoints include viability and local respiratory inflammation, marked by altered secretion of cytokines and chemokines. Pro-inflammatory cytokines, tumor necrosis factor alpha (TNF-&#945;), and interleukin 1 alpha (IL-1&#945;) were significantly increased in human PCLS after exposure to a sub-toxic concentration of HClPt. Even though the technique of PCLS has been substantially optimized over the past decades, its applicability for the testing of immunomodulation is still in development. Therefore, the results presented here are preliminary, even though they show the potential of human PCLS as a valuable tool in respiratory research.

In view of the 3Rs principle, respiratory models as alternatives to animal studies are evolving. Especially for risk assessment of respiratory substances, there is a lack of appropriate assays. Here, we describe the use of human precision-cut lung slices for the assessment of airborne substances.

Isolation and Adoptive Transfer of High Salt Treated Antigen-presenting Dendritic Cells

Excess dietary salt intake contributes to inflammation and plays a vital role in the development of hypertension. We previously found that antigen-presenting dendritic cells (DCs) can sense elevated extracellular sodium leading to the activation of the NADPH oxidase and formation of isolevuglandin (IsoLG)-protein adducts. These IsoLG-protein adducts react with self-proteins and promote an autoimmune-like state and hypertension. We have developed and optimized state-of-the-art methods to study DC function in hypertension. Here, we provide a detailed protocol for isolation, in vitro treatment with elevated sodium, and adoptive transfer of murine splenic CD11c+ cells into recipient mice to study their role in hypertension.

Here, we present a protocol to isolate dendritic cells from murine spleens by magnetic cell sorting and subsequent adoptive transfer into na&#239;ve mice. The model of high-salt activated dendritic cells was chosen to explain the step-by-step procedures of adoptive transfer and flow cytometry.
