HSC 4504 Final Exam PH Immunology 2024 Actual 50 Questions and Answers Solved/Verified 100% Which of the following is TRUE about innate immunity? Innate immunity improves with successive exposures to the same pathogen or antigen. Innate immunity employs B and T lymphocytes to generate a response.

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...

Harr - ISBBFrom the following, identify a specific component of the adaptive immune system that is formed in response to antigenic stimulation: A. Lysozyme B. Complement C. Commensal organisms D. Immunoglobulin D. Immunoglobulin is a specific part of the adaptive immune system and is formed only in response to a specific antigenic stimulation. Complement, lysozyme, and commensal organisms all act nonspecifically as a part of the adaptive immune system. These three components do not require ...
