Vi-Antigen

Vi antigen is a bacterial antigen that was discovered in 1972 during research into the origin of the human immunodeficiency virus (HIV). Vi antigens or Anti-Vi are proteins found on the surface of HIV and responsible for its ability to infect and reproduce in the host.

The discovery of Vi antigens was an important step in understanding how HIV infects cells of the immune system. HIV enters the host through damaged blood cells called CD4-positive cells, making it similar to Ashanti disease or leprosy. Klyuche
