Abstract:
The infectivity of HIV depends on overcoming APOBEC3 (A3) innate immunity, predominantly through the expression of the viral protein Vif, which induces A3 degradation in the proteasome. Disruption of the functional interactions of Vif enables A3 mutagenesis of the HIV genome during viral replication, which can result in a broadly neutralizing antiviral effect. Vif function requires self-association along with interactions with A3 proteins, protein chaperones, and factors of the ubiquitination machinery and these are described here as a potential platform for novel antiviral drug discovery. This Review will examine the current state of development of Vif inhibitors that we believe to have therapeutic and functional cure potential.

Introduction to Innate and Adaptive Immunity
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...
