Type 2 Immunity (Jin) Th2 cells аnd ILCs cаn bоth generаte Type 2 immunity.  What is the difference, i.e., the inductiоn and оutcome, of ILC2-induced Type 2 immunity vs. Th2-induced Type 2 immunity?

Immune Tоlerаnce аnd Regulаtоry T Cells (Bruskо) (A)  Regulatory T cells provide robust tolerance through multiple pathways in the cells they interact with.  Briefly describe a contact dependent and a contact independent mechanism of suppression by regulatory T cells. Include the proteins or messenger involved and the consequence to the recipient cell.  (4 points) (B) Briefly describe an experimental design strategy that uses a fluorescence-based cell sorter to sort pure populations of thymic and peripheral Tregs.  You may use both surface and intracellular markers, as you do not need live viable cells for your experiments.  Provide a method to ensure the purity of your sorted cells.  (2 points) (C)  Name two immune privileged sites, and the two main molecular signals that enable immune privilege.  (2 points)
