Fig. 4From: Expansion of circulating peripheral TIGIT+CD226+ CD4 T cells with enhanced effector functions in dermatomyositisTIGIT expression in purified TIGIT-negative CD4 T cells after prolonged stimulation. Purified CD4+CD25−TIGIT− T cells were stimulated by anti-CD3/CD28 and were re-analyzed 72 h later. TIGIT-positive CD4 T cells were obviously generated from TIGIT-negative cells after 72-h stimulation. The graph was representative of 2 independent experiments with 3 DM and 1 HCBack to article page
