Starting with CD4 counts of near-zero (this was the late 1990s), their median CD4 count rose to about 800 15 years after starting ART, but after that declined a little and plateaued at around 650. The researchers took purified resting CD4 T-cells from each participant’s blood and did two tests.
WebThis enhanced generation of peptide-specific effector CD4 T cells requires that the same splenic APC be pulsed with both peptides. Pulsed B cells, but not pulsed dendritic cells (DCs), can mediate CD4 T cell cooperation, which can be blocked by disrupting OX40-OX40L (CD134-CD252) interactions.
