The Ii antigen system is a human blood group system based upon a gene on chromosome 6 and consisting of the I antigen and the i antigen. [1] The I antigen is normally present on the cell membrane of red blood cells in all adults, while the i antigen is present in fetuses and newborns. [2]
In some cells, antigens bind to recycled MHC class II molecules while they are in the early endosomes, while other cells such as dendritic cells internalize antigens via receptor-mediated endocytosis and create MHC class II molecules plus peptide in the endosomal-lysosomal antigen processing compartment which is independent of the synthesis of ...
Similarly, there is SLA (Swine leukocyte antigens), BoLA (Bovine leukocyte antigens), DLA for dogs, etc. However, historically, the MHC in mice is called the Histocompatibility system 2 or just the H-2, whereas it has been referred to as the RT1 complex in rats, and the B locus in chickens.

This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
CLIP or Class II-associated invariant chain peptide is the part of the invariant chain (Ii) that binds to the peptide binding groove of MHC class II and remains there until the MHC receptor is fully assembled. CLIP is one of the most prevalent self peptides found in the thymic cortex [broken anchor] of most antigen-presenting cells.
It takes a lot to shock the internet at this point. After all, we're living in a world where people drain their ground beef with tampons and pancakes can be scrambled. However, one TikToker ...
Trump granted Wade clemency near the end of 2020, with less than a month left in his first presidential term. While Wade's case was sealed, the pardon effectively made it public. But Wade's crimes ...
Antigens generated endogenously within these cells are bound to MHC-I molecules and presented on the cell surface. This antigen presentation pathway enables the immune system to detect transformed or infected cells displaying peptides from modified-self (mutated) or foreign proteins. [5] [6]
