ABSTRACT
@#Abstract TGF-β/Smad signaling pathway has a wide range of biological activities and plays an important roles in regulating cell growth, adhesion, differentiation, cell dynamic balance, and immune responses. The higher activity of TGF-β/Smad signaling pathway may promote scar formation, organ fibrosis, immunosuppression, and late-stage cancer progression, while low activity may lead to inflammation, dysplasia, poor healing and oncogenesis. The function of the TGF-β/Smad signaling pathway is extremely complex and can exhibit inhibitory or enhancing effects on immunity and inflammation under different circumstances, but immunosuppressive and anti-inflammatory effects are dominant. During HIV infection, the TGF-β/Smad signaling pathway interacts with HIV in a complex manner as HIV proteins tat and gp120 can induce TGF-β expression. Meanwhile, this signaling pathway may also play a role in HIV infection and replication, latent virus reservoir, host immune deficiency and HIV-related inflammation. It is worth noting that even though TGF-β, which mainly exhibits anti-inflammatory effects, is induced by HIV, high levels of TGF-β do not seem to inhibit HIV-related inflammation. So far, the relationship between TGF-β/Smad signaling pathway and HIV infection has not been elucidated, and its role and mechanism in HIV infection and related illnesses need further exploration and validation. This review summarizes the relevant research progress on the TGF-β/Smad signaling pathway and HIV infection, and provides a reference for further understanding of HIV pathogenesis and exploring strategies of AIDS treatment.
