  2. Ii antigen system - Wikipedia

    en.wikipedia.org/wiki/Ii_antigen_system

    The Ii antigen system is a human blood group system based upon a gene on chromosome 6 and consisting of the I antigen and the i antigen. [1] The I antigen is normally present on the cell membrane of red blood cells in all adults, while the i antigen is present in fetuses and newborns. [2]

  5. Antigen presentation - Wikipedia

    en.wikipedia.org/wiki/Antigen_presentation

    Antigen presentation is a vital immune process that is essential for T cell immune response triggering. Because T cells recognize only fragmented antigens displayed on cell surfaces, antigen processing must occur before the antigen fragment can be recognized by a T-cell receptor.

  6. Immunogenicity - Wikipedia

    en.wikipedia.org/wiki/Immunogenicity

    However, strictly speaking, immunogenicity refers to the ability of an antigen to induce an adaptive immune response. Thus an antigen might bind specifically to a T or B cell receptor, but not induce an adaptive immune response. If the antigen does induce a response, it is an 'immunogenic antigen', which is referred to as an immunogen.

  7. MHC class II - Wikipedia

    en.wikipedia.org/wiki/MHC_Class_II

    In some cells, antigens bind to recycled MHC class II molecules while they are in the early endosomes, while other cells such as dendritic cells internalize antigens via receptor-mediated endocytosis and create MHC class II molecules plus peptide in the endosomal-lysosomal antigen processing compartment which is independent of the synthesis of ...

    en.wikipedia.org/wiki/CD74

    HLA class II histocompatibility antigen gamma chain also known as HLA-DR antigens-associated invariant chain or CD74 (Cluster of Differentiation 74), is a protein that in humans is encoded by the CD74 gene. [5] [6] The invariant chain (Abbreviated Ii) is a polypeptide which plays a critical role in antigen presentation.
