To determine the role of cytokines in the immunodeficiency of children infected with human immunodeficiency virus type 1 (HIV-1), we compared the antigen-specific (tetanus toxoid-induced) T-lymphocyte blastogenesis of HIV-1-infected patients with and without the addition of exogenous interleukin-1 and interleukin-2. Acquisition of in vitro antigen-specific immunologic function was seen in some patients after the addition of exogenous cytokines. The antigen-specific immunodeficiency in some HIV-1-infected children is due to defects in cytokine production rather than to an absence of antigen-specific T lymphocytes.
