WebbAs synthetic mimics of natural antigen-presenting cells, aAPCs encompass three basic signals required for T-cell activation: MHC–antigen complexes, costimulatory molecules and soluble immune modulating compounds. Both spatial and temporal organization of these signals during aAPC/T-cell contact is important for efficient T-cell activation. Webb12 jan. 2001 · On class I MHC molecules the peptide, usually derived from proteins in the cytoplasm of any cell, is generated by the proteasome, transported into the endoplasmic reticulum, loaded onto MHC …
Webb14 apr. 2024 · The main objective of antigen processing is to orchestrate the selection of immunodominant epitopes for recognition by CD4 T cells. To achieve this, MHC class II … Webb13 apr. 2024 · The two major classes of glycoproteins entrusted with antigen presentation are the MHC class I and class II molecules, which present antigenic peptides to CD8+ T cells and CD4+ T cells, respectively.
WebbToday, we know that the function of MHC class II molecules on antigen-presenting cells (APCs) is not limited to their role as antigen-presenting structures; they are flexible receptors that, by triggering a variety of signaling pathways, can regulate APC activities from proliferation and maturation to apoptosis.
WebbThe T cell recognizes and interacts with the antigen-class II MHC molecule complex on the membrane of the antigen presenting cell. An additional co-stimulatory signal is then produced by the antigen presenting cell, leading to activation of the T cell.
