Step by step
Solved in 2 steps
- The Complement System Kills Microorganisms The complement system supplements the inflammatory response by directly killing microorganisms. Describe the life cycle of complement proteins, from their synthesis in the liver to their activity at the site of an infection.The Adaptive Immune Response Is a Specific Defense Against Infection Compare the general inflammatory response, the complement system, and the specific immune response.Complement proteins function in defense by _______. a. neutralizing toxins b. enhancing resident bacteria c. promoting inflammation d. forming pores that cause pathogens to disintegrate e. both a and b f. both c and d
- The Adaptive Immune Response Is a Specific Defense Against Infection Name the class of molecules that includes antibodies, and name the five groups that make up this class.The Adaptive Immune Response Is a Specific Defense Against Infection Identify the components of cellular immunity, and define their roles in the immune response.Individuals infected with herpes simplex virus (HSV) mount protective antibody responses directed against surface glycoproteins of the virus. 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. And then formulate a robust testable hypothesis for your…

You perform an ELISA to measure the antibody response of the C3-deficient and normal mice (referred to as wild-type – WT)…Which of the following complement components are generated during the classical pathway and bind independently to the membrane surface promoting immune adherence and opsonizing effects? C3b O C3d O C1q O C2In your own personal understanding, why are complements important in cellular and humoral mediated immunity? also, cite basic example.
- Some bacterial cells avoid the killing effects of activated complement proteins. How might they do this?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 pathogensEach is an effect of complement activation EXCEPT interference with viral replication. bacterial cell lysis. increased blood vessel permeability opsonization. increased phagocytic activity.
