Homework Answers
Answer
A person who failed to make MHC receptor molecule would not be able to activate the T cell-based immunity because of T-cell ( Th or Tc) require antigen presented over MHC molecule by antigen presenting cells to get activated and formed memory and effector cells. So, If MHC is not present then there will be no T- cell activation and adaptive immunity will be badly hampered.
Intracellular and extracellular antigen presentation will be affected which activates the cytotoxic T-cells and helper T-cell respectively. So change in the MHC I will impact the Tc activation and response whereas MHC II will impact the Th cell response.

Adaptive Immunity: Second Line of Defense—Cellular Defenses The T-cell receptors and CD4 and CD8 molecules interact with major histocompatibility complex (MHC) proteins. MHC proteins are found on most cells of the body. There are two variations, or classes, of MHC proteins. MHC class I is expressed on the surface of most cells of the body such as skin cells, liver cells, and others. Should a cell become infected with a virus, viral antigens are processed in the cells and expressed...

Upregulation of MHC class Il molecules on the surface of antigen-presenting cells occurs during infection. What is this aided by? Select one: a. Destablization of the interaction between the invariant chain and MHCl in the ER O b. Accumulation of HLA-DO in response to inflammatory cytokines c. Deacidification of endocytic vesicles d.
