The Role Of Actin Associated Sptbn1 Host Factor In Hiv-1 Infection In Microglial Cells, Hannah Matheney

MSU Graduate Theses

Human immunodeficiency virus (HIV) is a chronic illness affecting more than 32.7 million individuals worldwide. The virus infects immune cells, weakening the immune system overtime eventually leading to acquired immunodeficiency syndrome (AIDS) if left untreated. Infection starts with a fusion step, followed by uncoating of the HIV capsid once in the cytoplasm of the cell. HIV uses host cell proteins to complete the infection process, like the actin associated factor, SPTBN1. The Hulme lab has previously shown that SPTBN1 knockdown by siRNA in microglial cells decreased HIV infection and delayed uncoating of HIV. Because fusion is prior to uncoating, it …
