Immune features of graft‐derived mucosal‐associated invariant T cells predict gastrointestinal graft‐versus‐host disease
Gastrointestinal acute graft‐versus‐host disease (GI aGVHD) remains a major complication after allogeneic haematopoietic stem cell transplantation (allo‐HSCT), and early risk identification and intervention are essential for improving outcomes. Mucosal‐associated invariant T (MAIT) cells are mucosa‐enriched unconventio...
