WebbAn antigen-presenting cell ( APC) or accessory cell is a cell that displays antigen bound by major histocompatibility complex (MHC) proteins on its surface; this process is known as antigen presentation. T cells may recognize these complexes using their T cell receptors (TCRs). APCs process antigens and present them to T-cells.

Webb15 dec. 2024 · Major histocompatibility complex (MHC) molecules are well-known for their role in antigen (cross-) presentation, thereby functioning as key players in the communication between immune cells, for example dendritic cells (DCs) and T cells, or immune cells and their targets, such as T cells and virus-infected or tumor cells. … WebbThe nascent MHC class II protein in the rough endoplasmic reticulum (RER) binds a segment of the invariant chain (Ii; a trimer) in order to shape the peptide-binding groove and prevent the formation of a closed conformation.
