  • Chronic restraint stress (RS) induces anxiety-like behavior in mice, linked to γδT17/γδTreg cell imbalance.
  • γδT17 cells increase while γδTreg cells decrease in RS mice, affecting anxiety behavior.
  • Depletion of γδT17 cells with αIL-17 antibody reduces anxiety-like behavior, whereas γδTreg depletion worsens it.
  • Metabolomic changes in RS mice highlight alterations in purine and nucleotide metabolism, notably increased xanthine and hypoxanthine.
  • Exogenous xanthine exacerbates neuronal damage in RS mice, crossing the blood-brain barrier and accumulating in the brain.
  • The study identifies a γδT17/γδTreg-xanthine axis as a novel link between immune dysregulation, metabolic changes, and anxiety-like behavior.
