Safe and effective adjuvant therapies for chemotherapy\u2010related immune injury remain limited.

AB probiotic intervention alleviated these injuries dose\u2010dependently: it restored thymus and spleen indexes, rebalanced serum cytokines, improved core immune functions, and repaired ileal mucosal pathological damage. Furthermore, probiotic treatment was accompanied by elevated fecal SCFA concentrations, upregulated tight junction gene expression, recovered aryl hydrocarbon receptor (AhR)\/ERK\/STAT3 transcription, enriched beneficial bacterial genera, and suppressed opportunistic pathogens.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION<\/jats:title>\n                    <jats:p>Compound AB probiotics alleviate CTX\u2010induced immunosuppression in mice, and this effect correlates with restored gut microecology, enhanced SCFA metabolism, repaired intestinal barrier, and activated AhR signaling.
