Is anybody familiar with an approach for direct isolation of Th1 effector CD4+ T cells from human peripheral blood? Perhaps in terms of sorting or via cytokine capture?
HI, I have done this and its detailed in the paper below. Basically use CD45 to isolate Lymphocytes. Then go for CD4+ and gating on these cells add in CD183 and CD196. The Th1 cells will be a minor population in peripheral blood and will be in bottom right quadrant, Th2 will be in Bottom left and Th17 will be top left. Use FMO to set the borders. I use PC7 for CD196 and PE for CD183. The Th1 will specifically release cytokines TGFb and IFN gamma.
