ABSTRACT:
G-protein behaves as an essential molecular switch for cellular signaling. Its diversity promotes the signaling variation in different cell types. HIV latent infection requires G-protein signaling. Additionally, a cell type preference exists in HIV latent infection, particularly for memory CD4 T cells, known as a primary viral reservoir. Based on previous studies, we hypothesized that G-protein might serve as a potential marker to identify HIV reservoirs. In this study, we successfully developed a standard assay that can profile multiple G proteins in HIV infected T cells. Through this system, we identified major differences in G protein expression profiles among various human cell types, especially human naive and memory CD4 T cells. This research established a vital tool in understanding the cellular environment permitting HIV persistence.
