Target

  • Function

    Enhances all basic T-cell responses to a foreign antigen, namely proliferation, secretion of lymphokines, up-regulation of molecules that mediate cell-cell interaction, and effective help for antibody secretion by B-cells. Essential both for efficient interaction between T and B-cells and for normal antibody responses to T-cell dependent antigens. Does not up-regulate the production of interleukin-2, but superinduces the synthesis of interleukin-10. Prevents the apoptosis of pre-activated T-cells. Plays a critical role in CD40-mediated class switching of immunoglobin isotypes.

  • Tissue specificity

    Activated T-cells. Highly expressed on tonsillar T-cells, which are closely associated with B-cells in the apical light zone of germinal centers, the site of terminal B-cell maturation. Expressed at lower levels in thymus, lung, lymph node and peripheral blood leukocytes. Expressed in the medulla of fetal and newborn thymus.

  • Involvement in disease

    Immunodeficiency, common variable, 1

  • Sequence similarities

    Contains 1 Ig-like V-type (immunoglobulin-like) domain.

  • Post-translational
    modifications

    N-glycosylated.

  • Cellular localization

    Secreted and Cell membrane.

Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution 2) for 30 mins. Rabbit specific IHC polymer detection kit HRP/DAB (ab209101) was used as the secondary antibody. Hematoxylin was used as a counterstain. Sporadically positive staining in the germinal center of human tonsil, performed on a Leica Biosystems BOND™ RX instrument.
      The section was incubated with ab105227 for 30 mins at room temperature.
