We have utilized combination antiretroviral therapy following human immunodeficiency virus type 1-induced human CD4(+) thymocyte depletion in the SCID-hu mouse to examine the immune competence of reconstituting thymocytes which appear following administration of combination therapy. These cells express a normal distribution of T-cell receptor variable gene families and are responsive to costimulatory signals. These results suggest that normal thymic function may be restored following antiretroviral treatment.
