Why are oncofetal proteins good targets for immune surveillance against tumors? A. NK cells recognize these antigens. B. Negative selection in the thymus has not taken place for these antigens. C. Positive selection has eliminated T cells that recognize these antigens. D. Because these antigens are ubiquitously expressed at all stages of an organism’s life. Any help would be wonderful,...
1) Heavy chain antibodies have major implications for therapeutic purposes because _________. A) they have smaller variable domains and can be purified more easily B) they only have heavy chains and no light chains and are more easily engineered C) nanobodies are easily constructed from the constant regions of these antibodies D) they are derived from camels and related animals,...
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...
1. The specific immune response art 1 of 3 is the second line of defense after anatomical and chemical barriers involves memory of antigens from previous exposure. is the first line of defense in the immune system. involves millions of B and T cells - each individual cell can recognize many different antigens. eBook 2. T cells arise and finish...

What is the mechanism of action for monoclonal antibodies? Target tumor-specific antigens on the surface of some cancer cells Introduce the immune system to fragments of weakened or dead bacteria Accelerate and fully engage immune cells to create a robust immune response Remove immune cells from the body, and retrain them to identify and kill specific antigens Question 24 A patient scheduled to receive a fourth...

QUESTION 11 How is the immune system able to recognize a limitless number of different antigens and epitopes? While each lymphocyte carries receptors that recognize only one type of epitope, the immune system produces a wide variety of lymphocytes each of which carries unique receptors A genetic "memory" of the pathogens your parents encountered (and their parents and so on)...
