Beyond SCFAs, arginine reinforces CD8 + T cell activity and inhibits Tregs via mTOR signaling (77), whereas Trp metabolites exhibit divergent effects: Kyn induces CD8 + T cell exhaustion through AhR-dependent programmed death-1 (PD-1) upregulation (78), contrasting with DATs enhancement of IFN-I-primed T cell expansion (79), and LPS exhibits dose-dependent immunomodulation, acutely activating T cells before promoting exhaustion during chronic exposure (80)
