Co-inhibitory receptor (immune checkpoint) expression analysis in human T cell subsets

Zachary R. Healy, David M. Murdoch

Description: This panel was optimized to quantify inhibitory receptor expression on CD4 and CD8 T cells from differentiation and activation subsets. Six inhibitory (i.e., immune checkpoint) receptors (PD-1, TIM-3, LAG-3, CD160, BTLA, CTLA-4) were chosen based upon previously published observations suggesting their role in modulating CD4 and CD8 T cell activation in response to persistent antigen exposure. Furthermore, given the important observations that inhibitory receptor expression varies by differentiation and prior antigen experience, markers of T cell differentiation status and prior antigen experience (CCR7, CD45RA, CD28, CD127, KLRG1) were also included. This panel was developed and optimized for use in cryopreserved human peripheral blood mononuclear cells (PBMCs), although it has also been applied in fresh PBMCs as well as other bodily fluids (e.g., malignant ascites).
