T cells use the T cell antigen-receptor (TCR) to recognize their antigens, which are often in the form of peptides bound to major histocompatibility complex molecules (MHC), also called HLA (human ...
An intracellular sensor that tracks the quality of so-called MHC-I molecules which aid the immune system in identifying and eliminating dangerous cells, including tumor cells has been discovered ...
Countless molecular "radio masts" - the MHC-I molecules - are responsible for presenting these fragments. They are assembled inside the cell and then transported to the membrane, the lipid layer ...
