SpletHigher CD4 + /CD8 + ratio was associated with lower PD-1 expression on SARS-CoV-2-specific CD8 + T cells (0.34-fold effect, P = 0.02). HIV status was strongly associated with PASC (odds ratio 4.01, P = 0.008), and levels of certain inflammatory markers (IL-6, TNF-alpha, and IP-10) were associated with persistent symptoms. Splet25. sep. 2006 · The interpretation of these findings, however, is complicated by the finding that PD-1 − HIV-specific CD8 T cells also have increased susceptibility to apoptosis. It is possible that other factors such as the level of T cell activation are involved. Cells expressing very high levels of PD-1 were much more susceptible to death signals ...
