This presentation process places antigens into a context in which the cell presenting the antigen can be recognized by the effector cell as “self-derived,” and the antigen can be seen as foreign. This process is called antigen presentation and it is essential to antigen specific development ...
Antigen presentation is the process by which protein antigen is presented to lymphocytes in the form of short peptide fragments. These are associated with antigen-presenting molecules such as MHC class I or MHC class II on the surface of antigen-presenting cells (APCs). Latest Research and Review...
This process of antigen presentation allows T cells to “see” what proteins are present in the body and to form an adaptive immune response against them. In this article, we shall discuss antigen processing, presentation, and recognition by T cells. Antigen Presentation Antigens are delivered to...
Similarly, endogenous and viral proteins can generate peptide–MHC class II complexes that are recognized by CD4 + T cells in a process involving autophagy. Understanding the processes and mechanisms by which antigens are captured, processed and loaded onto MHC molecules for presentation to T cells...
To review the recent literature on the process of antigen sampling, processing, presentation, and initiation of immune recognition that take place on mucosal surfaces and their draining lymph nodes, especially the intestinal mucosa. We have also included recent observations from our own laboratory to ...
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,...

ERp57. Peptide loading proceeds in a two-step process. In step one, peptide-receptive molecules load with peptide cargo that is not refined in terms of its affinity (off-rate). A subsequent step involving tapasin (TPN), calreticulin (CRT) and ERp57 results in the 'editing' of this...
? Peptide binding to class II molecules involves replacing a fragment of invariant chain (CLIP) by a process catalyzed by non-classical MHC molecule HLA-DM. ? Presentation of nonpeptide antigens (lipid and glycolipid) derived from bacteria involves the class I-like CD1 molecule. ...
