NKG2D Is an Activating Receptor Expressed on NK Cells $\gamma$ $\delta$

question 14

Multiple Choice

NKG2D is an activating receptor expressed on NK cells, $\gamma$ : $\delta$ T cells, and some cytotoxic $\alpha$ : $\beta$ 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-E molecules that bind leader peptides of other HLA class I molecules
• E) HLA-G molecules just like those expressed on the fetal-derived cells in the placenta
