Autologous Ans Bone marrow transplant that is from the patients own stem cells *Chapter 12: HIV Disease and AIDS* Ans HIV and AIDS affect on CD8+ T cells Ans Reverses CD4:CD8 ratio CD8 T-cells play a crucial role in controlling HIV replication during the early phase of infection. HIV-specific CD8 T-cells are targeted at the dominant viral variant and their emergence is associated with a rapid fall in viral load before the development of an antibody response. A majority of the CD8 T-c...
