Duаrte - Mаnipulаtiоn оf the Immune Respоnse (A) Several therapies for unwanted immune responses target the interaction between CD80/86 (B7) on the antigen presenting cell (APC) and CD28 on the T cell. From a mechanistic standpoint, briefly define why blocking this specific interaction is considered a “tolerance-inducing” strategy. (2 points) (B) Name the metabolic or cellular fate of a T cell that recognizes its specific antigen (Signal 1) while the co-stimulatory pathway (Signal 2) is being blocked. (1 point) (C) Abel is studying the immunosuppressive effects of corticosteroids for allogeneic skin transplantation in mice. Treatment Outcomes Corticosteroids only Prolonged skin graft survival Corticosteroids + exogenous IL-2 + constitutively active anti-CD28 antibody Skin grafts infiltrated by T cells Skin grafts rejected Based on your knowledge of the 3-signal model of T-cell activation and the mechanisms of action of corticosteroids on APCs and T-cells, briefly define why the addition of IL-2 and anti-CD28 was able to override the immunosuppressive effect of steroids.

Bаyer - Mucоsаl Immunity Mucоsаl immune systems must balance rapid, prоactive defense with strict control of inflammation. (A) List three examples about how specialized components of the innate and adaptive immune compartments contribute to immune exclusion and homeostasis. (3 points) (B) For each example, briefly define how that mechanism prevents unnecessary inflammatory responses to commensal microbes while still enabling effective protection against pathogens. (6 points) (C) A patient ingests a novel oral vaccine designed to elicit strong mucosal immunity without triggering gut inflammation. Briefly define how the inductive and effector compartments of GALT coordinate to generate this targeted immune response. (2 points) (D) For the oral vaccine described in part C, briefly define the roles of (1) antigen sampling, (2) lymphocyte activation and homing, and (3) IgA production. (3 points)
