PICTURES OF HIV / AIDS: HIV, Human Immunodeficiency Virus, is the retrovirus that causes AIDS. HIV has a complex architecture. Its RNA genome is contained in a centrally placed bullet shaped core. This core sits inside a cage of matrix proteins. The matrix is enveloped in cell membrane that was acquired during budding from the host cell. Anchored in the matrix, and projecting through the viral envelope, are spikes that allow the virus to attach to host cells.
