WebbIn the HHR thymus, the medulla was underdeveloped and nTreg number was decreased. Array comparative genome hybridization revealed the deletion of an NK cell lectin-like receptor gene, Ly49s3, detecting MHC class I molecules on target cells, in the chromosome 4q42 region in HHRs. WebbThe thymic development of this Treg population required antigen presentation and co-stimulatory signals provided by DCs, implying that Aire-dependent antigen must be transferred from medullary thymic epithelial cells to DCs.
