Select all that apply. MHC class I peptide loading occurs in four steps. Peptide loading of class I molecules generated from intracellular proteins occurs in the endoplasmic reticulum. ⒸMHC class II molecules are loaded before they are part of a vesicle capable of fusing with a phagolysosome. Peptide loading of class II molecules occurs later in the secretory pathway than that of MHC class I molecules.
