CCR6 and type 1 diabetes mellitus: Children with recent-onset T1D expressed less chemokine receptor 6 (CCR6), a T cell homing receptor, and less B-cell lymphoma-2 (BCL-2), an anti-apoptotic molecule, than control children, suggesting the reduction in circulating MAIT cells early in T1D onset could result from directed recruitment to inflamed tissues (the pancreas)?, or death by apoptosis (6).
