Diagram Of Hiv Infection. Acquired immunodeficiency syndrome aids when the cd4 lymphocyte count drops below 200microliter then the stage of clinical aids has been reached. A diagram of the hiv spike protein green with the fusion peptide epitope highlighted in red and a broadly neutralizing antibody yellow binding to the fusion peptide.
Hiv stands for human immunodeficiency virus a pathogen that works by attacking the human immune system. It is roughly spherical with a diameter of about 120 nm around 60 times smaller than a red blood cell. Hiv is different in structure from other retroviruses.
Aids results in a gradual and persistent decline and failure of the immune system resulting in heightened risk of life threatening infection and cancers.
Human immunodeficiency virus hiv is a complex rna virus of the genus lentivirus within the retroviridae family. The structural biology of hiv hiv human immunodeficiency virus is composed of two strands of rna 15 types of viral proteins and a few proteins from the last host cell it infected all surrounded by a lipid bilayer membrane.
