Uty HY Peptide (246-254) Mouse – Immunology – Antigens/Epitotes/Pools/Librairies

Graft versus host (GVH) rejection has been linked to the mismatch of minor histocompatibility (H) antigens even when matched for the major antigens of the major histocompatibility complex (MHC). The minor H antigens are encoded by autosomal and Y chromosome genes, they function as supports to MHC during synthesis. The prevention of GVH disease induced by minor H antigens is currently managed with immunosuppression. Using models and H antigen epitopes can provide research in to how GVH disease could be better managed by inducing tolerance. Mice are the preferred model for H antigen research due to their homogeneity apart from the Y chromosomal genes of the males. The peptide provided here is the T-cell epitope for the male-specific transplantation antigen (H-Y). It was derived from the mouse ubiquitously transcribed tetratricopeptide repeat gene on the Y chromosome (Uty) protein. Uty HY Peptide has been used to investigate transplantation tolerance of male to female grafts by inhibiting the effector CD4+ and CD8+ T-cell responses.
