Figure Lengend Snippet: JHU083 inhibited T cells activation in vivo . Mice of Vehicle-AIH and JHU083-AIH group were intravenously injected with 8ml/kg ConA, and Vehicle-WT group was injected with normal saline of equal volume. JHU083-AIH group was gavaged with 0.3mg/kg JHU083 24h and 1h before ConA injection, and mice of Vehicle-WT and Vehicle-AIH group were treated with equal vehicle at the same time points. (A, B) Flow cytometry was applied to analyze the expression of CD25 and CD69 of CD4(+) (A) and CD8(+) (B) T cells. Data were expressed as means ± SEM. * P < 0.05 and ** P <0.01.

Article Snippet: The antibodies used in the flow cytometry were as follows: CD4 (FITC, E-AB-F1097C), CD8a (PE, E-AB-F1104D), CD25 (PE-Cy5, E-AB-F1102G), CD69 (PE-Cy7, E-AB-F1187H), IL4 (PE, E-AB-F1204UD), IL17A (APC, E-AB-F1272E) were purchased from Elabscience Biotechnology (Wuhan, China), antibodies IFNγ (APC-Cy7, cat# 561479) was purchased from BD Biosciences (UK), and Granzyme B (PE-Cy7, cat# 372213) was purchased from Biolegend (San Diego, CA, USA).

Figure Lengend Snippet: DON treatment suppressed T cells activation in vitro . Freshly separated spleen cells were stimulated with 1.5mg/ml ConA with or without treating 2.5μM DON, and cells were analyzed 24h after ConA stimulation. (A, B) The expressions of activation markers CD25 and CD69 in CD4(+) (A) and CD8(+) (B) T cells were examined by flow cytometry. Data were expressed as means ± SEM. ** P <0.01, and *** P <0.001.

Figure Lengend Snippet: The function of DON to mTOR signaling may be mediated by amino transporter amino transporter SLC7A5. (A) qRT-PCR was applied to analyze amino acid transporters SLC7A5 and SLC1A5 mRNA levels. (B, C) Flow cytometry was applied to analyze the degree of activation (expression of CD25 and CD69) of CD4(+) (B) and CD8(+) (C) T cells with or without treating LAT1-IN1. The levels of phosphorylated mTOR (D) as well as phosphorylated P70S6K (E) were examined by western blotting. Data were expressed as means ± SEM. *P < 0.05, **P <0.01, and ***P <0.001. ns, not significant.
