Question
Chapter 22, Problem 10DYKB
Summary Introduction
Introduction:
The defense mechanisms of the body are exhibited by the immune system of the body. These immunological agents fight against foreign pathogens. Some of these responses are generalized, some are specific.

- Pathogens produce several types of proteins that can inhibit complement activation. The importance of complement activation as an innate immune defense against infections is illustrated by: The evolution of complement avoidance strategies by many pathogens The large number of proteins involved in the complement pathway The large number of complement regulatory pathways expressed by the host The existence of three different mechanisms for initiating complement activation The ability of the membrane attack complex to lyse some pathogensarrow_forwardIngestion of complement-tagged pathogens by phagocytes is mediated by receptors for the bound complement proteins. Even when the complement cascade fails to proceed beyond generating the C3 convertase, complement activation is effective at inducing pathogen uptake and destruction. This process of immune protection is mediated by: Activation of complement inhibitory receptors on phagocytes that promote pathogen uptake Activation of soluble proteases in the serum that disrupt pathogen membranes Engagement of complement receptors on phagocytes by C3b and its cleavage products which promotes phagocytosis Engagement of complement receptors on B cells that promotes antibody production Stimulation of antimicrobial peptide secretion by phagocytesarrow_forwardTrue or False: FHL patients show increased susceptibility to infection because secretion of IFN-γ in cytotoxic granules is impaired.

These antibodies are critical to viral clearance. The act to neutralise any virus trying to infect a person’s cells as well as activating the classical pathway of complement and cytotoxic cell-mediated killing of infected target cells. Having a deficiency in the complement component C3 greatly impairs a person’s ability to control HSV infections. To understand this further, you will investigate this in the lab. Using C3-deficient mice, you infect them with HSV at day 0 and then a second time 4 weeks later. A hypothesis is a tentative answer to a scientific question and is an important part of practical experiments. A testable hypothesis is statement that can be proved or disproved as a result of experimentation. Q1. State the problem that you are trying to solve.
