Introduction	HIV-1 ａnd HIV-2 appear to package their RNA differently. HIV-1 binds to any appropriate RNA whereas HIV-2 preferentially binds to mRNA which creates the Gag protein itself. This means that HIV-1 is better able to mutate. HIV-2 is transmitted in the same ways as HIV-1: Through exposure to bodily fluids such as blood, semen, tears ａnd vaginal fluids. Immunodeficiency develops more slowly with HIV-2. HIV-2 is less infectious in the early stages of the virus han with HIV-1. The infectiousness of HIV-2 increases as the virus progresses. Major differences include reduced pathogenicity of HIV-2 relative to HIV-1, enhanced immune control of HIV-2 infection ａnd often some degree of CD4-independence. Despite considerable sequence ａnd phenotypic differences between HIV-1 ａnd 2 envelopes, structurally they are quite similar. Both membrane-anchored proteins eventually form the 6-helix bundles from the N-terminal ａnd C-terminal regions of the ectodomain, which is common to many viral ａnd cellular fusion proteins ａnd which seems to drive fusion. HIV-1 gp41 helical regions can form more stable 6-helix bundles than HIV-2 gp41 helical regions however HIV-2 fusion occurs at a lower threshold temperature （25°C）, does not require Ca2+ in the medium, is insensitive to treatment of target cells with cytochalasin B, ａnd is not affected by target membrane glycosphingolipid composition.
