  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]

  3. Kidd antigen system - Wikipedia

    en.wikipedia.org/wiki/Kidd_antigen_system

    The Kidd antigen system (also known as Jk antigen) are proteins found in the Kidd's blood group, which act as antigens, i.e., they have the ability to produce antibodies under certain circumstances. The Jk antigen is found on a protein responsible for urea transport in the red blood cells and the kidney. [ 1 ]

  5. Human blood group systems - Wikipedia

    en.wikipedia.org/wiki/Human_blood_group_systems

    The term human blood group systems is defined by the International Society of Blood Transfusion (ISBT) as systems in the human species where cell-surface antigens—in particular, those on blood cells—are "controlled at a single gene locus or by two or more very closely linked homologous genes with little or no observable recombination between them", [1] and include the common ABO and Rh ...

  6. Diego antigen system - Wikipedia

    en.wikipedia.org/wiki/Diego_antigen_system

    The Diego antigen (or blood group) system is composed of 21 blood factors or antigens carried on the Band 3 glycoprotein, also known as Anion Exchanger 1 (AE1). The antigens are inherited through various alleles of the gene SLC4A1 ( Solute carrier family 4), located on human chromosome 17 .

  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 ...

  8. Kell antigen system - Wikipedia

    en.wikipedia.org/wiki/Kell_antigen_system

    The Kell antigen system (also known as the Kell–Cellano system) is a human blood group system, that is, a group of antigens on the human red blood cell surface which are important determinants of blood type and are targets for autoimmune or alloimmune diseases which destroy red blood cells. The Kell antigens are K, k, Kp a, Kp b, Js a and Js ...

  9. Tolerogenic therapy - Wikipedia

    en.wikipedia.org/wiki/Tolerogenic_therapy

    Tolerogenic therapy aims to induce immune tolerance where there is pathological or undesirable activation of the normal immune response.This can occur, for example, when an allogeneic transplantation patient develops an immune reaction to donor antigens, or when the body responds inappropriately to self antigens implicated in autoimmune diseases.
