Antigen Processing and Presentation of Exogenous Peptide Antigen via MHC Class I

Antigen Presentation, Exogenous Antigen via Major Histocompatibility Complex 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.
