Introduction:

Lymphoid tissues can be defined as organized structures that are a vital part of the immune system. It protects the body from infections and potential pathogens. Some of the important lymphoid tissues are spleen, bone marrow and thymus.

Expert Solution

Explanation of Solution

The lymphoid tissues are divided into two types according to their functions. They are primary and secondary lymphoid tissues. Primary lymphoid tissues include bone marrow and thymus. Apart from them, every other type of lymphoid tissue is known as secondary lymphoid tissue. The main secondary lymphoid tissues include the spleen, mucosa-associated lymphoid tissues (MALT) and lymph nodes. These also include gut-associated lymphoid tissue (GALT), such as the adenoids, tonsils, Peyer's patches, appendix and bronchial-associated lymphoid tissues (BALT).

Conclusion

Therefore, primary lymphoid tissues are bone marrow and thymus and the main secondary lymphoid tissues include the spleen, mucosa-associated lymphoid tissues (MALT) and lymph nodes.

Lymphoid tissues can be defined as organized structures that are a vital part of the immune system. It protects the body from infections and potential pathogens. Some of the important lymphoid tissues are spleen, bone marrow and thymus.

Expert Solution

Explanation of Solution

Central or primary lymphoid tissues are the anatomical locations where lymphocytes get developed and reach the state of maturation required where they can respond to a potential pathogen. B cells are matured in the bone marrow and fetal liver before entering the circulation, whereas T cells mature leave the bone marrow at the immature stage and mature in the thymus. Both lymphocyte lineages are derived from a common hematopoietic stem cell.

Secondary lymphoid tissues are the anatomical locations where lymphocytes encounter antigen and immune responses get induced. Antigen is delivered to the secondary lymphoid tissues through an afferent lymphatic vessel. It is reserved in the lymphoid tissue to encounter with lymphocytes having antigen specific receptors.

Conclusion

Therefore, primary lymphoid tissues are the anatomical locations where lymphocytes get developed and reach the state of maturation required where they can respond to a potential pathogen. Whereas, secondary lymphoid tissues are the anatomical locations where lymphocytes encounter antigen and immune responses get induced.

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
