We have created a novel antigen-specific T cell isolation technology based on nanoparticle artificial antigen presenting cells (aAPCs). Nanoparticle aAPCs have peptide-loaded MHC on the surface that allows antigen-specific T cell binding and activation alongside co-stimulatory activation. aAPCs are also paramagnetic, and thus can be used to enrich rare antigen-specific T cells using a magnetic field. We have optimized and studied key nanoparticle properties of size, ligand density, and ligand choice and their influence o...

With the rise of many immunotherapies, there is a need to be able to characterize and control immune responses. In particular, the adaptive immune response is of interest because of the specificity and durability of the cells. Recently, chimeric-antigen-receptor T cell therapies have been approved for cancer therapy; however, the antigen-receptors are based off the common cell surface antigen CD19, instead of the antigens specific to the cancer1. Beyond the specificity, immunotherapies can also suffer from the lack of control, and limited understanding the dynamic immune response within cancer or autoimmunity.
One of the challenges of studying antigen-specific responses is their extremely low frequency, e.g., antigen-specific T cells are 1 of every 104 to 106 T cells2,3. Thus, to investigate which T cells are present or responding, the cells need to either be enriched and expanded, or their signal need to be amplified. It is expensive and difficult to maintain the feeder cells using current techniques that focus on the expansion of antigen-specific cells. Current techniques that focus on amplifying the signal of antigen-specific T cells, like the enzyme-linked immunospot (ELISPOT) assay, limit the re-use of those T cells4. Finally, because of low sensitivity, often these two techniques need to be combined for antigen-specific enumeration.
To address these issues, we have developed the magnetic nanoparticle-based artificial antigen presenting cell (aAPC)5,6,7,8. The aAPC can be functionalized with an antigen-specific signal-peptide loaded major histocompatibility complex (pMHC)-and co-stimulatory molecules-e.g., an anti-CD28 antibody-to both enrich antigen-specific T cells and then subsequently stimulate their expansion (Figure 1). The particles can thus be a cost-effective off-the-shelf product that can be both customized to meet antigen-specific stimulations yet standardized across experiments and patients. Performing the enrichment and expansion process results in hundreds to thousands-fold expansion of antigen-specific CD8+ T cells and can result in frequencies up to 60 percent after just one week, enabling the characterization or therapeutic use of the large number of cells. Herein, we describe how to make nanoparticle aAPCs, some critical design considerations in choosing the nanoparticle properties, and demonstrate some typical results from utilizing these particles in isolating and expanding rare antigen-specific CD8+ T cells.

enrich and expand rare antigen-specific t cells with magnetic nanoparticles

We have developed a tool to both enrich and expand antigen-specific T cells. This can be helpful in cases such as to A) detect the existence of antigen-specific T cells, B) probe the dynamics of antigen-specific responses, C) understand how antigen-specific responses affect disease state such as autoimmunity, D) demystify heterogeneous responses for antigen-specific T cells, or E) utilize antigen-specific cells for therapy. The tool is based on a magnetic particle that we conjugate antigen-specific and T cell co-stimulatory signals, and that we term as artificial antigen presenting cells (aAPCs). Consequently, since the technology is simple to produce, it can easily be adopted by other laboratories; thus, our purpose here is to describe in detail the fabrication and subsequent use of the aAPCs. We explain how to attach antigen-specific and co-stimulatory signals to the aAPCs, how to utilize them to enrich for antigen-specific T cells, and how to expand antigen-specific T cells. Furthermore, we will highlight engineering design considerations based on experimental and biological information of our experience with characterizing antigen-specific T cells.

To complete a successful enrichment and expansion of antigen-specific T cells, the peptide-loaded MHC-Ig and co-stimulatory molecules should be successfully attached to the aAPC particle. Based on the 3 methods of particle attachment, we provide some representative data for a successful conjugation procedure outcome (Figure 5a). Indeed, if the ligand density is too low, then there will not be effective stimulation of antigen-specific CD8+ T cells where this o...

Enrich and Expand Rare Antigen-specific T Cells with Magnetic Nanoparticles

Antigen-specific T cells are difficult to characterize or utilize in therapies due to their extremely low frequency. Herein, we provide a protocol to develop a magnetic particle which can bind to antigen-specific T cells to enrich these cells and then to expand them several hundred-fold for both characterization and therapy.
