antigen processing and presentation of exogenous peptide antigen via MHC class I
antigen processing and presentation of exogenous peptide antigen via mhc class i
The process in which an antigen-presenting cell expresses a peptide antigen of exogenous origin on its cell surface in association with an MHC class I protein complex. The peptide antigen is typically, but not always, processed from a whole protein. Class I here refers to classical class I molecules.
