"Insulin-like growth factor-I (IGF-I) and erythropoietin treatment protect against HIV/gp120-mediated neuronal damage in culture and in vivo, in part, through cooperative activation of phosphatidylinositol 3-kinase/Akt/GSK-3beta signaling" . "HIV-1 gp120-induced PI3-kinase activity and calcium mobilization are inhibited by pertussis toxin and blocking antibodies directed against CCR5 and CXCR4, suggesting that this signaling is mediated through these chemokine receptors" . "CCR5 activation by gp120 triggers the assembly of endogenous Lyn, PI3K, and Pyk2 and is associated with PI3K and Pyk2 translocation from the cytoplasm to the membrane where they colocalized with Lyn" .
