Textbook Question
Chapter 26.5, Problem 1CR
Pathogens may colonize host tissues when appropriate nutrients and growth conditions are present, such as on mucosal surfaces, especially where the composition of the normal microbiota has been altered. Innate responses to microbial invasion and tissue damage are initiated by the release of chemokines, which recruit phagocytes and other immune cells to sites of infection.
Describe a scenario in which microorganisms invade body tissues. What factors allow for the migration of phagocytes to sites of infection?

Which of the following statements are TRUE about the process of inflammation? (Select all that apply)
Inflammation can occur with only the innate immune response involved.
Leukocytes or white blood cells are found everywhere in the body to carry out inflammation as needed
Growth factor from non-skin cells is responsible for the formation of scar tissue in place of the damaged skin cells
The increase of warmed blood to a site of injury comes from the hypothalamus
Phagocytes engulf invading microbes and dead white blood cells
Phagocytosis is used during inflammation to make sure there is no debris
Although the complement cascade can be initiated by antibodies bound to the surface of a pathogen, complement activation is generally considered to be an innate immune response. This is because:
Two of the three pathways for complement activation are initiated by constitutively produced recognition molecules that directly interact with microbial surfaces.
When the complement cascade leads to the formation of a membrane-attack complex, the pathogen is killed.
Several of the soluble products generated by complement activation lead promote the inflammatory response.
Complement proteins bound to the pathogen promote uptake and destruction by phagocytic cells.
The C3 convertase is only produced when complement activation is initiated by antibody binding to a pathogen.
Macrophages and neutrophils both contribute to extracellular pathogen protection. Describe their common characteristics, differences in structure and function, and if one were eliminated from the innate immune response, explain which one would be more detrimental to the body and why.

- 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.arrow_forwardMicrobial 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.arrow_forwardList the sequence of events in an inflammatory response and describe each step.arrow_forward
- What major events take place during an inflammatory reaction, and how do they contribute to pathogen destruction?arrow_forwardDescribe Two Features of phagocytes that are essential in their response to microbial invasion.arrow_forwardThe effector mechanisms that are recruited to clear an infection depend on the infectious agent. In addition to producing distinct innate responses locally at the site of infection, the different cytokines produced during type I, type 2, or type 3 immune responses also induce distinct adaptive immune responses that are tailored to the eradication of the three different classes of pathogens. One example is the production of different classes of antibodies during type I, type 2, or type 3 responses. Which step during the induction of the adaptive immune response is the key to generating and coordinating the three different immune modules?arrow_forward
