  • tissue
  • Because the HLA is a chemical tag that distinguishes "self" from "nonself," the antigen is important in the rejection of transplanted tissue and in the development of certain diseases (e.g., insulin-dependent diabetes). (encyclopedia.com)
  • The database is searchable by the official CD designation of the antigen as well as by synonyms and other keywords including associated diseases and tissue/organ names. (apple.com)
  • The uptake and processing of antigens by macrophages in the tissue is an initial, critical step in most immune responses. (cliffsnotes.com)
  • receptors
  • Also, an antigen is a molecule that binds to Ag-specific receptors, but cannot necessarily induce an immune response in the body by itself. (wikipedia.org)
  • It was expanded to refer to any molecule or a linear molecular fragment that can be recognized by highly variable antigen receptors ( B-cell receptor or T-cell receptor ) of the adaptive immune system. (wikipedia.org)
  • Whether one T-cell receptor jointly recognizes a virus product in association with a class I antigen or whether separate T-cell receptors independently recognize the virus product and the class I antigen, respectively, is not yet resolved (for a recent review see ref. 2). (springer.com)
