NK cells express several receptors that have intracellular domains of either ITAMs or ITIMs. Based on these domains with differing purposes, when do NK cells become activated to kill a target cell? What could be different about a cancer cell that causes it to be targeted by an NK cell? What could be different about virally-infected cells that causes it to be a target?

1. Use graph to represent difference between NK cells vs B, T cells and NK cells vs Macrophage/ Neutrophils. 2. Use a drawing to show positive feedback regulation NK cells contribute during infection, the drawing needs to meet the following requirements: 1) Identify cytokines NK cells respond to and produce 2) Identify immune cells that responds to cytokines produced by NK cells 3) Show ligand/receptor interaction of these cytokines 3. Identify the mechanism of how NK cells eliminate harmful cells...

Imagine a patient unable to express MHC II, at least in their B cells. Answer the following. A). What is required to induce MHC II expression? Short answer - briefly, list steps. B) What is the role of MHC II (what does it present and to what receptor and cell type)? C) What effects would you expect B cell deficiencies in MHC II expression to have?
