Study Notes
HIV Infection
- The main target of HIV infection is CD4+ T cells.
HIV-1
- HIV-1 is the most virulent and prevalent form of HIV.
HIV Virion Components
- The components of HIV virion are two copies of single-stranded RNA, Reverse Transcriptase, Integrase, Protease, and structural proteins.
HIV-2
- HIV-2 is less virulent and less prevalent than HIV-1, but still causes AIDS.
AIDS
- The end stage of the disease associated with CD4+ T cell depletion and multiple opportunistic infections is AIDS (Acquired Immune Deficiency Syndrome).
Cells Infected by HIV
- HIV mainly infects CD4+ T cells, macrophages, and dendritic cells.
HIV-2 Prevalence
- HIV-2 is the cause of infection in specific regions like West Africa and Mozambique.
Retrovirus Genus
- The genus of retrovirus that includes the subspecies HIV-1 and HIV-2 is Lentivirus.
HIV Virion Characteristics
- HIV virion has a lipid bilayer envelope, is spherical in shape, and is approximately 100-120 nm in diameter.
AIDS (Again)
- The end stage of the disease associated with CD4+ T cell depletion and multiple opportunistic infections is AIDS (Acquired Immune Deficiency Syndrome).
