- 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.Which of the following substances is not produced by phagocytes todestroy engulfed microorganisms?a. hydroxyl radical b. superoxide anion c. hydrogen peroxide d. bradykininHigh numbers of “good” bacteria are foundin the intestine and on the skin. The immune system needs to protect these areasfrom invading microbes, but cannot respond as strongly to the normal microflorawithout causing problems. What are somepossible ways that immune cells coulddistinguish “good” from “bad” bacteria?
- As it relates to infectious diseases, discuss the types of immune responses ( i.e., innate) and immune functions ( i.e., antibody production)Enhanced phagocytosis of a cell by the binding of aspecific protein is called ________.a. endocytosisb. opsonizationc. anaphylaxisd. complement activationA signaling molecule from microbes recognized by phagocytes isa. pyrogen b. PAMP c. complement d. lectin
- Describe the potential problems that would arise if a personhad an acquired inability to phagocytose pathogensPatients with a history of tuberculosis often show scars and other lesions in the lungs and sometimes experience recurrent infection. Account for these effects on the basis of the inflammatory responseMr. Samara Austin, a twenty-four-year footballer sustained a bruise on his right knee during training on the field and reported 3 days later with redness and oedema on the site. Explain the inflammatory process leading to the manifestations.
- During inflammaion, host tissue may be damaged owing to the release of toxic oxygen derivatives produced by activated phagocytes. List some of hese toxic species and explain what cellular/biochemical mechanisms limit these damaging off-target effects.Microbial recognition and tissue damage initiate an inflammatory response. True/False: The inflammatory response is characterized by four classic symptoms: heat, redness, pain, and swelling. In some instances, this response can be triggered by stimuli that are non-infectious such as asbestos, a process known as ‘sterile inflammation.’ When exposure to the stimulating trigger is persistent, a state of chronic inflammation can result. This process is likely to be detrimental to the health of the host.Compare and contrast the immunodeficiency observed in SCIDpatients to that of AIDS patients. What cell types are affectedby each condition?
