Additional Information

HIV-1 infection results in a decrease of CD4 T cells, an increase in CD8 T cells, a decrease in the CD4:CD8 ratio, and a progressive destruction of immune function. Enumeration of CD4 and CD8 T cells in HIV-1 seropositive patients may be used for prognostic purposes, to monitor disease progression and retroviral therapy.
