There is increasing interest in DN T cells since they are being implicated in different pathologic conditions such as autoimmune disorders, cancer, graft tolerance, and primary diseases of the kidney including acute kidney injury (AKI), glomerulonephritis8,13. Therefore, there is need to better understand and characterize the pathophysiologic functions of DN T cells. However, currently there is a lack in understanding of these cells&#8217; function as compared to CD4 and CD8 T cells. A ma...

Erratum: Isolation of Double Negative &#945;&#946; T Cells from the Kidney

Peripheral &#945;&#946;TCR+CD3+CD4-CD8-double-negative (DN) T cells are divided into various subsets that possess distinct phenotypes and functions1-4. DN T cells are poorly understood but increasingly being implicated in pathophysiological immune responses in different disease models4-6.
DN T cells are a unique immune cell type that is increasingly implicated in the regulation of various immune and autoimmune responses and the modulation of allotransplant tolerance. 4-6,9 They are rare in the peripheral blood and secondary lymphoid organs (spleen and lymph nodes). However, they are major residents of the normal kidney and gut epithelium10-12. Very little is known about their function7 in the kidney in the steady state and under pathological conditions such as acute kidney injury (AKI) associated with kidney transplant.
Because of the intricate roles of different immune cells in regulating immune responses including alloresponses, defining the role of each player is critical in understanding alloresponses and designing new therapeutics. Given the significant numbers of DN T cells present in the kidney under physiologic and different disease conditions, DN T cells are likely to play a critical role in regulating immune and autoimmune responses in mice and humans, and alloresponses in transplant recipients. Accumulating though still scattered evidence implicates DN T cells in both pathogenic and immunosuppressive functions but it is poorly understood why and how they exhibit a specific harmful or suppressive function and how the environment influences them.
Due to their low abundance in the kidney, improved methods of isolation are necessary.
There is currently no standard protocol for isolation of DN T cells from the non-lymphoid tissues. Our protocol describes a novel method for isolation of DN T cells from the kidney; however, the method can also be used for various non-lymphoid tissues.

isolation of double negative &#945;&#946; t cells from the kidney

There is currently no standard protocol for the isolation of DN T cells from the non-lymphoid tissues despite their increasingly reported involvement in various immune responses. DN T cells are a unique immune cell type that has been implicated in regulating immune and autoimmune responses and tolerance to allotransplants1-6. DN T cells are, however, rare in peripheral blood and secondary lymphoid organs (spleen and lymph nodes), but are major residents of the normal kidney. Very little is known about their pathophysiologic function7 due to their paucity in the periphery. We recently described a comprehensive phenotypic and functional analysis of this population in the kidney8 in steady state and during ischemia reperfusion injury. Analysis of DN T cell function will be greatly enhanced by developing a protocol for their isolation from the kidney.
Here, we describe a novel protocol that allows isolation of highly pure ab CD4+ CD8+ T cells and DN T cells from the murine kidney. Briefly, we digest kidney tissue using collagenase and isolate kidney mononuclear cells (KMNC) by density gradient. This is followed by two steps to enrich hematopoietic T cells from 3% to 70% from KMNC. The first step consists of a positive selection of hematopoietic cells using a CD45+ isolation kit. In the second step, DN T cells are negatively isolated by removal of non-desired cells using CD4, CD8, and MHC class II monoclonal antibodies and CD1d &#945;-galcer tetramer. This strategy leads to a population of more than 90% pure DN T cells. Surface staining with the above mentioned antibodies followed by FACs analysis is used to confirm purity.

Wild type C57BL/6 (B6) kidney contains approximately 1.5-2.1 x 106 mononuclear cells per kidney. Approximately less than 10% are hematopoietic CD45+ cells. For the preparation of kidney mononuclear cells (KMNC), the kidneys are cut into small pieces as shown in Figure 1 followed by digestion using 5% collagenase.
This is followed by performing a density gradient centrifugation to collect KMNC layer (Figure&#160;2, left panel). KMNC were t...
