Expert Solution & Answer

Summary Introduction

To review:

The phagocytic cells found in blood and lymph and the organs containing fixed phagocytes.

Introduction:

The immune system of the body includes various organs which are involved in protecting the body from foreign agents or pathogens (disease causing organisms). The immunity in the body can be innate or adapted (specific). These two act as a protective barrier to eliminate the pathogens from the body, hence, protecting it from infections.

Explanation of Solution

The innate or inherited immunity is nonspecific in nature. It provides the primary defense mechanism to the body against all type of pathogens. There are different forms of innate immunity with respect to their functions such as phagocytic cells provide protection by destroying the pathogen by ingesting the harmful foreign bodies, debris, proteins and so on. The list below shows phagocytic cells found in blood and lymph:

Neutrophils

Monocytes

Kupffer cells

Alveolar macrophages

Histocytes (tissue macrophages)

The Kupffer cells are found in the liver and alveolar macrophages in lungs. The neutrophils are present in blood stream and all tissues. The phagocytes destroy the pathogens coming to their ways by digestion with toxins or other ways to protect the body.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?  3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
