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...

Describe the hierarchy of the immune system in terms of white blood cells Immune System-> White Blood Cells-> Agranulocytes-> Lymphocytes-> B & T Lymphocytes Lymphocytes -Type of white blood cell in the immune system, made by bone marrow -Includes: T-Cells, B Cells, and Natural Killer (NK) cells (Cytotoxic T Cells) --All of these help to fight cancer, Viruses, and Bacteria B Cell Lymphocytes -Have receptors where antigens attach -They learn to recognize different antigens -...

Question 1 5 / 5 pts Short answer Explain how the skin’s physical barrier makes it inhospitable to microorganisms. Your Answer: The skin contains keratin which makes it salty, and it also contains antimicrobials that makes it inhosptable to microorganisims. It has closely packed cells in multiple layers that are continuously being shed. Keratin covers the skin, which creates a salty, acidic environment inhospitable to microbes. It also contains antimicrobial proteins and lysozymes t...

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 ...
