- AB 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.
