HIV particle attaching to a T lymphocyte (white blood cell), computer artwork. Glycoproteins Gp41 and Gp120 form receptors (orange and red projections on the virus particle, top) that bind to CD4 receptors (blue projections, bottom) on the T lymphocyte. HIV (human immunodeficiency virus) causes AIDS (acquired immune deficiency syndrome). The virus consists of an RNA (ribonucleic acid) genome, surrounded by a protein nucleocapsid core (red,centre). The whole virus is enclosed in an envelope derived from the host cell's plasma membrane. Viral matrix proteins (blue and grey, inside the virion) link the viral envelope to the nucleocapsid. HIV infects the immune system's T-lymphocytes and ultimately kills them, leading to a very weak immune system.
