Question 9 of 14 Which of the following acts as a signal for the dendritic cell to begin cross-presentation? Presence of self-reactive CD4 T cells O Expression of endoplasmic reticulum (ER) chaperones calnexin and calreticulin O Phagocytosis and processing of extracellular antigens O Cytokine release following the activation of engaged CD4 T cells Question 10 of 14 Which of the following are true about MHC class I and MHC class II peptide loading? 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 Il molecules are loaded before they are part of a vesicle capable of fusing with a phagolysosome. Peptide loading of class Il molecules occurs later in the secretory pathway than that of MHC class I molecules.
