Effect of glutamine metabolism on in-vitro induction of Th1, Th17 and
Treg cells. Splenocytes from DO11.10 RAG2−/− mice were
ex-vivo cultured with cytokines promoting Th1, Th17 and Treg cell proliferation
and tested under different concentration of glutamine and DON. After five days
of incubation, the cells were harvested and analysed for the differentiation of
the targeted immune phenotypes. The histogram A shows the frequencies of Th1
(CD4+IFN-γ+) cells with media containing 0, 1,
and 2 mM concentrations of glutamine. Histogram B shows the frequencies of cells
expressing IFN-γ at varying concentrations of DON. The histograms C and D
and E and F show the same data for Th17 and Treg, respectively. The data
represent mean results ± SEM. Dunnett's multiple comparisons test
were performed as post-hoc test following the one-way ANOVA (experiments
repeated three times with n=3).
