    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).
