- Whether the statement "To guarantee that the antigen-presenting cells in the thymus will display a complete repertoire of self peptides to allow elimination of self-reactive T cells, the thymus recruits dendritic cells from all over the body" is true or false.In LeVay’s study, what evidence argues against the idea that INAH-3 volume depends on AIDS rather than sexual orientation?Where is the thymus located? Describe its structure andfunction
- When T cells are activated by recognizing peptide:MHC complexes on dendritic cells in the lymph node, they up-regulate the receptor CD69. For T cells expressing a given T-cell receptor, the initial strength of the T-cell receptor signal can be modulated by varying the number of peptide:MHC complexes on the dendritic cells, or by varying the affinity with which the T cell-receptor binds to the peptide:MHC complexes. As a result, T cells stimulated with stronger T-cell receptor signals will maintain high expression of CD69 for one or two days longer that if those same T cells were stimulated with weaker T-cell receptor signals. Therefore, T cells stimulated with weaker T-cell receptor signals are likely to: Die by apoptosis Undergo more rounds of proliferation that T cells stimulated with stronger T-cell receptor signals Migrate to the B-cell zones of the lymph node Have reduced effector functions, such as cytokine production Egress from the lymph node 1–2 days earlier than T cells…Explain why each choice (a-d) is correct or incorrect. All but one of the following occurs during the inflammatory response. Select the example below that does NOT describe the process of inflammation. a. Inflammation increases capillary permeability. b. Chemotaxis draws leucocytes to the site of injury. c. Vasoconstriction prevents excessive blood loss due to injury. d. Release of prostaglandins results in pain.is a group of plasma proteins thatwhen activated stimulate inflammation,attract phagocytes, and enhancephagocytosis.

Group of answer choices True FalseHow does PKC's signaling role change in response to growth factor signaling versus an immune responseState the action(s) of each of the following signal molecules:a. IGF-1b. PDGFc. epidermal growth factord. IRS-1e. tumor necrosis factor
- "To guarantee that the antigen-presenting cells in the thymus will display a complete repertoire of self peptides to allow elimination of self-reactive T cells, the thymus recruits dendritic cells from all over the body is true or false.TLRs activate NFkB, AP-1, and IRF transcription factors to induce the expression of inflammatory cytokines and type I interferons. A key feature of TLR signaling is the ability to induce inflammatory cytokine gene expression extremely rapidly following TLR stimulation. This is accomplished by signaling pathways using several mechanisms to activate transcription factors that are already present in the cell prior to TLR stimulation, but are kept in an inactive state. These signaling pathways use all of the following mechanisms EXCEPT: Induced ubiquitination leading to protein degradation Induced ubiquitination inducing protein–protein interactions Induced phosphorylation leading to nuclear translocation Induced phosphorylation leading to kinase activation Induced phosphorylation preventing protein degradationWhy are CD8+/αβT-cells important? Explain the function of the mature activated CD8+/αβT-cell and list 3 cytotoxic effector molecules they secrete and 3 cytokines they secrete.
