Table II. Learning outcomes of challenges 6–8 of Mission: Immunity!

Challenges	Learning Outcomes
6	To describe the Ag presentation pathways involved in the presentation of viral Ags on MHC-I and MHC-II
7	To describe the signals for CD8 or CD4 T cell activation; binding of TCR to specific MHC-I or MHC-II receptors respectively and the presence of CD80/86 To state the cytokines for the polarization of Th cells to Th1, Th2, or regulatory T cells
8	To describe the signals for B cell activation (MHC-II binding to TCR; CD40L binding to CD40) and the process of affinity maturation To state the cytokine (IFN-γ) for the class-switching to produce IgG
