WebApr 12, 2024 · [Journal of Virology] Using a serum-free in vitro system, scientists further delineated the role of TGF-β signaling in mediating HIV-1 infection of activated and resting memory CD4+ T cells. WebHIV-1 replicates in immune cells called CD4+ T-cells and uses a process of cell-to-cell spread (CCS) to transmit infection rapidly from one cell to another. We have recently discovered that when HIV-1 spreads by CCS it manipulates T-cells to make them better targets for the virus, allowing HIV-1 to infect and replicate in resting T-cells that are … WebApr 11, 2024 · All have maintained viral undetectability. 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.
