Time (weeks) O IgE IgG O IgA IgD O IgM Antibody concentration In plasma
- QUESTION 6 Which of the following is a response of our innate defense system? adaptive immunity inflammation cytotoxic T cell response helper T cell response O adaptive immunity inflammation O cytotoxic T cell response O helper T cell responseQuestion 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.
