Immunology Exam 2 - Questions and Answers NKG2D is an activating receptor expressed on NK cells, : T cells, and some cytotoxic : T cells. When stressed or infected cells up-regulate receptors that bind to and activate NKG2D molecules, the stressed or infected cells will be killed. This pathway relies on the fact that stressed or infected cells up-regulate: A. All classical MHC class I molecules B. HLA-C molecules that bind KIRs C. MHC class Ib genes such as MICA, MICB, and RAET1 D. Qa-1 and HLA...

((Given image)) A stem cell is fate determined once it has received the Self Renewal signal. As result, which genes are newly expressed? (Check all that apply) - -ID genes -DIV genes -DET genes ((Given)) Shown here are four ligands (M, H, K, and L) and their corresponding receptors along with three genes (U, V, and W) whose activity the receptor controls through signal transduction. The arrows indicate gene activation, the T-bars indicate gene repression. If either U or V is required to ...
