antigen processing and presentation of endogenous peptide antigen via MHC class I via ER pathway
antigen processing and presentation of endogenous peptide antigen via mhc class i via er pathway
The process in which an antigen-presenting cell expresses a peptide antigen of endogenous origin on its cell surface in association with an MHC class I protein complex following intracellular transport via an ER pathway. The peptide is typically a fragment of a larger endogenous protein which has been degraded within the cell and becomes associated with the MHC class I molecule in the ER. Class I here refers to classical class I molecules.
