Fig. 2. NMT1 controls proinflammatory T cell differentiation.
CD4+CD45RA+ T cells from patients with RA and age-matched healthy individuals were stimulated for 72 h. Lineage-determining transcription factors (T-bet, RORγt, GATA-3) were analyzed 4 days after stimulation. IFN-γ and IL-17 were measured by intracellular cytokine staining on day 6. Neutral lipid droplets were detected with BODIPY 493/503. (a-f) CD4+ T cells from RA patients were transfected with an NMT1 expression vector or a control vector. Data (mean ± SEM) from 6 RA patients compared by paired Mann-Whitney-Wilcoxon rank test. (g-l) CD4+ T cells from healthy individuals were transfected with NMT1 siRNA or control siRNA. Data (mean ± SEM) from 6 healthy donors. Paired Mann-Whitney-Wilcoxon rank test. *p < 0.05.
