Fig. 4From: CD4+CD25High Treg cells in HIV/HTLV Co-infected patients with neuropathy: high expression of Alpha4 integrin and lower expression of Foxp3 transcription factorCorrelation between the frequency of Treg cells and CD4+ activated lymphocytes. In a, b and c, correlation between the frequency of Treg cells and CD4 activated cells (CD4+HLA-DR+) in control HIV Neur and HIV/HTLV Neur groups. Only in co-infected group a positive correlation was seenBack to article page
