HIV-1 proteins, including Tat, gp120, and Nef, activate macrophages (MΦ), which is consistent with the fact that HIV-1 infection is characterized by sustained immune activation. Meanwhile, MΦ are functionally classified into two types: proinflammatory M1-MΦ and anti-inflammatory M2-MΦ. We show that HIV-1 proteins, particularly Nef, preferentially activate M2-MΦ. Extracellular Tat, gp120, and Nef activated MAPK and NF-κB pathways in human peripheral blood monocyte-derived MΦ. However, the… CONTINUE READING
