karedapinnalises ER-s ja esitletakse membraanil CD8+ Tc rakkudele. Eksogeenne rada Eksogeensed antigeenid võetakse sisse ja degradeeritakse endotsüütilises kompartmendis happeliste, pH-sõltuvate endosomaalsete ja lüsosomaalsete ensüümide poolt ja need kombineeruvad MHC klass II molekulidega CD4+ Th rakkudele esitlemiseks. Professional APCs specialize in presenting antigen to T cells. They are very efficient at internalizing antigens, either by phagocytosis (macrophages and dendritic cells) or by receptor-mediated endocytosis (B cells), processing the antigen into peptide fragments and then displaying those peptides, bound to a class II MHC molecule, on their membrane. Non-professional antigen presenting cells include all nucleated cell types in the body. They use an MHC class I molecule coupled to beta-2 microglobulin to display endogenous peptides on the cell membrane. 18. T rakkude areng. Positiivne ja negatiivne selektsioon tüümuses. AIRE.
