In your justification, be sure to provide: How the complement control protein normally functions, At least two negative impacts it would have on the body, and List any other complement control proteins or aspects of the immune response that would be impacted.
this is for hypersensitivities topic Please select one example of surface molecules that inhibit complement protein activation and describe the mechanism of action ( please include one image and reference page)
Describe the complement system. Is the order ofprotein interactions important? Why or why not?Identify the components of the mannose-binding lectinpathway for complement activation.
Explain the "antigen recognition by cells of adaptive immunity" in a simple way. Thank you, I will use this for infographics. NOTE: BULLET FORM
Name and describe a laboratory test which detects inflammation in the body (no abbreviations please). Is this test diagnostic? Very briefly explain your answer
Write TRUE is the statement is True, otherwise write FALSE and explain why the statement is False. The complement system involves a set of genes that distinguish foreign cells from body cells. The alternative complement activation pathway involves the cleavage of C5 to form C9. The type of interferon present late in an infection is gamma interferon. Interferons cause muscle aches, chills, and fever. Toll-like receptors act to cause phagocytic chemotaxis. Lymphocytes are large agranulocytes. Opsonization occurs when a phagocyte’s pseudopods surround a microbe and fuse to form a sac. Defensins are antimicrobial peptides of the first line of defense.
Which one of these does not pertain to Complement Select one: A. Is a series of proteins present in the plasma. B. Is a specific defense mechanism. C. Plays a role in destroying bacteria. D. Is involved in the inflammatory response.
Macrophages perform the final job of removingtissue debris and other products of infection.Indicate some of the possible effects when thesescavengers cannot successfully complete thework of phagocytosis.
Three effects of complement activation: (1) inflammation (2) opsonization (3) cytolysis of pathogens. Describe the three effects in at least one complete sentence for each. You should clearly explain *how* complement activation results in the three different effects.
