- Explain weather discuss the effects of ageing on the functionality of T cell Discuss weather if there certain pathways or mechanicms that inudce aging of the fuctionalty of t cell. Provide a diagram to back answer.At first glance, it would seem a dangerous strategyfor the thymus to actively promote the survival, matura-tion, and emigration of developing T cells that bind weaklyto self peptides bound to self MHC molecules. Would itnot be safer to get rid of these T cells, along with those thatbind strongly to such self-peptide–MHC complexes, as thiswould seem a more secure way to avoid autoimmune reac-tions?Explain weather discuss the effects of ageing on the functionality of T cells Explain the process of the e3ffect of agiing on the fuctionalty of t cells Provde clincial data to back answer.
- Some primitive organisms, such as invertebrates, have no lymphocytes and thus lack an adaptive immune system, but they have somecomponents of an innate immune system, including phagocytes andcertain protective proteins. What are some general features of innateimmunity that make it very valuable to organisms lacking more specific antibody- and cell-mediated responses? What are some disadvantages to having only an innate immune system?Some Type-II immunopathology mediated autoimmune diseases have manifestations inmultiple different organs. Discuss how antibodies to one single antigen can cause damage inmultiple sites throughout the body. Things you might discuss include, but are not limited towhere the antigen could be expressed, how antibodies are made, how they bind antigen,where they circulate, the ratios of antigen to antibody, mechanisms of the immune systemthat result in cellular/tissue damage, or how immune system components can affect otherorgans. You might also comment on what makes one antigen an attractive target rather thananother. Please do NOT comment on all the things listed above, they are just to get youthinking. If you are having trouble getting started, it might help to think about a specificdisease which affects multiple organs.Visit this website (http://openstaxcollege.org/l/chemotaxis) to learn about phagocyte chemotaxis. Phagocyte chemotaxis is the movement of phagocytes according to the secretion of chemical messengers in the form of interleukins and other chemokines. By what means does a phagocyte destroy a bacterium that it has ingested?
- The Adaptive Immune Response Is a Specific Defense Against Infection Identify the components of cellular immunity, and define their roles in the immune response.Which of the following is not a part of innate immunity? a. phagocytic cells e. inflammation b. fever f. complement activation c. histamines g. presenting antigen d. cytokines h. all take partDescribe humoral immunity and cell-mediated immunity.Include in your answer the types of immune cells involvedin each, the location of antibodies and receptors that bindforeign antigens, the mechanisms by which invading cellsare destroyed, and the role of helper T cells in facilitatingboth responses.
