Can you please explain why the natural killer cell in innate immunity don't attack our red blood cells?
Natural killer also called as NK cells are a kind of lymphocyte which plays a key role in innate immune response by recognizing and eliminating the virus infected cells and tumor cells.
Step by step
Solved in 2 steps
- 1) According to the video, what is another name for the innate immune sys and what does this system do? 2) According to the video, what causes inflammation and what cells cause it? 3) According to the video, what happens to neutrophils after they consume a pathogen? 4) According to the video, natural killer cells; what do they do? 5) The adaptive/acquired immune system can tell the difference between types of pathogens: true or false? 6) According to the video, helper t- function: 7) According to the video, cytotoxic t cells function: 8) According to the video, memory cells function:Use the following choices for the next set of questions. A choice may be used zero or more times: a)MHC class I b) MHC class Il C) both MHC class I and II d) neither MHC class | or II e) cannot be determined 21) expressed on T cells 22) captures antigens present in endosomes 23) strongly affected by proteasomal inhibition 24) downregulated by many viruses 25) the genes responsible for expression are monomorphic, meaning that identical alleles are shared throughout the populationFigure 42.11 Which of the following statements about T cells is false? Helper T cells release cytokines while cytotoxic T cells kill the infected cell. Helper T cells are CD4+, while cytotoxic T cells are CD8+. MHC II is a receptor found on most body cells, while MHC I is a receptor found on immune cells only. The T cell receptor is found on both CD4+ and CD8+ T cells.
- What is the difference between innate immunity and adaptive immunity?Herd immunity means that the entire population (not just those who are vaccinated) are protected from a disease. What is one way that herd immunity protects an unvaccinated person (such as an infant who is too young to be vaccinated or a person who is immunocompromised)?What do you mean by innate immunity? Give and explain the components of innate immunity.
- Use the following choices for the next set of questions. A choice may be used zero or more times: a)Complement b) B cells c) T cells d) more than one of these 6)Part of the innate immune response 7)Often found concentrated in the lymph nodes 8)Expresses MHC Class I 9)Can be a plasma cell 10) Capable of inducing cytotoxicity of self cells 11) Directly participates in ADCC 12) Forms membrane attack complex 13) Undergoes affinity maturation 14) Produces molecules capable of neutralizing soluble toxins in serum 15) Undergoes somatic hypermutation 16) Produces molecules which serve as opsonins 17) Relies on immunologic signal transduction for proper operation 18) Undergoes clonal expansion 19) Considered part of the endothelium 20) Capable of producing granzymeJohnny has just been infected and needs your help in letting him know how his body is fighting the infection. To do so, describe how the innate and adaptive immune systems work together. You should address the following: 1. define adaptive and innate immunity; 2. Describe the role of natural killer cells (how do they work); 3. what are antigen presenting cells and what is their function, what are MHCs?; 4. describe the role of the complement system; 5. what is the role of interferons?; 6. How do helper T cells, cytotoxic T cells and B lymphocytes work make sure you address adaptive immunity memory?; 7. Define HIV, which cells do they attack and why do some individuals develop persistent lymphadenopathy (swollen or enlarged lymph nodes)?The correct order of words to describe how innate immune response responds to a pathogen that has gotten by the physical and chemical barriers is: À) Skin, Saliva, Cytokines, Macrophage B)Macrophage, Cytokines, Neutrophil, Natural Killer Cell C) Neutrophil, Cytokines, Killer T Cell, Antibodies D) Antigen, Macrophage, B Cell, Killer T Cell
- Can you create fill-in-blank questions for me about the Immune System.

Question 14 options: A) neutrophils, macrophages, T cells B) neutrophils, macrophages, NK cells C) B cells, T cells, and NK cells D) basophils, T cells, mast cells
