Antigen processing and presentation is the process by which protein antigen is ingested by an antigen-presenting cell (APC), partially digested into peptide fragments and then displayed on the surface of the APC associated with an antigen-presenting molecule such as MHC class I or MHC class II,...
Antigen processing and presentation Self-MHC Restriction: T cells can only recognize Ag when it is presented with a self-MHC molecule on the membrane of an antigen presenting cell (APC). Self-MHC restriction of TH cells A. Rosenthal & E. Shevach APC T Cell Self-MHC restriction of TC ...
Antigen processing provides the host with a means of scanning samples of the proteins constantly being produced and turned over in the body. If a nonself protein is detected in the course of this sampling, the immune response kicks into action to counter the threat. Each antigen-presenting ...
Are you studying antigen processing and presentation? STEMCELL has partnered with Nature Reviews Immunology to bring you this valuable reference. Provides an updated overview of intracellular pathways and mechanisms by which antigens are captured, processed and loaded onto MHC class I, class II and ...
Antigen processing and presentation are the cornerstones of adaptive immunity. B cells cannot generate high-affinity antibodies without T cell help. CD4+T cells, which provide such help, use antigen-specific receptors that recognize major histocompatibility complex (MHC) molecules in complex with peptide...

Adaptive, cell-mediated immunity involves the presentation of antigenic peptides on class I MHC molecules at the cell surface. This requires an ABC transporter associated with antigen processing (TAP) to transport antigenic peptides generated in the cytosol into the endoplasmic reticulum (ER) for loa...
