WebApr 4, 2024 · Vitiligo is mediated by T cells and antibodies against melanoma-expressed antigens that cross-react with normal melanocytes 2. In this context, it was presumed that other irAEs might similarly be due to antigen cross-reactivity. However, the majority of irAEs are tumor-type agnostic, raising doubt about this hypothesis. WebCross-reactivity is the ability of an antigen to bind with an antibody that was raised to a different antigen. It may arise by one of two mechanisms: shared epitopes on multivalent antigens, or conformational similarity of epitopes.
