Inhibition of protein kinase C-mediated CD4 down-regulation by oxidative stress in T lymphocytes.


The CD4 molecule acts as a receptor for class II MHC molecules to stabilize Ag recognition by the TCR and as a high affinity receptor for HIV-1. In this study, we investigated the effect of oxidative stress on the level of CD4 expression on cultured peripheral blood T lymphocytes (PBL blasts). As previously reported, we observed that the surface CD4 was… (More)
