Glutamine increased the proliferative response and the lymphokine-activated killer cell activity of blood mononuclear cells isolated from normal healthy subjects (n = 6) in a dose-dependent manner, with optimum at 0.3–1.0 mM. The relative fraction of CD3+, CD4+, CD8+, CD14+, CD16+, and CD19+ cells was not changed by glutamine at a concentration of 0.6 mM, except in the phytohemagglutinin-stimulated proliferation experiment where the fraction of CD4+, and therefore CD3+ cells, increased. The natural killer cell activity was not influenced by glutamine. Human immunodeficiency virus (HIV)-seropositive subjects (n = 8) who performed concentric bicycle exercise for 1 h at 75% of maximal O2 consumption had an overall lower phytohemagglutinin-stimulated proliferative response, compared with the HIV-seronegative control group (n = 7). The proliferation during exercise was lower in both the HIV-seropositive and the HIV-seronegative group. Addition of glutamine in vitro did not normalize the lower proliferation in the HIV-seropositive group or the attenuated proliferation seen during exercise in both groups.
