<qa>  What is the name of the immunodeficiency that is characterized by?Untreated HIV-1 infection is characterized by progressive immune dysfunction and the development of opportunistic infections and AIDS-associated malignancies. Highly active antiretroviral therapy HAART has been successful in suppressing HIV replication and restoring partial immune function. However, HIV-specific immunity remains poor, as evidenced by rapid rebound of HIV-1 RNA following HAART withdrawal. Studies of individuals with acute HIV-1 infection, as well as those who are long-term nonprogressors, have suggested that robust HIV-specific immune responses are associated with control of HIV-1 viremia. Dendritic cells DCs are potent antigen presenting cells that may increase HIV-specific immune responses. This protocol will evaluate the use of DCs to help control HIV infection.
