Advanced Immune Mechanisms and Cellular Interactions Quiz

Questions: 18 | Attempts: 12 | Last updated: Nov 13, 2025

Sample Question
Naive T-cells are activated by strong signaling from APCs; weak signaling or interactions with immature APCs induces T cell anergy.

-CD4+ and CD8+ cells are stimulated by IL-2 acting as an autocrine or paracrine factor to induce proliferation and/or maturation. -expose to IL-4 drives CD4+ Th cells towards Th2 function while continues exposure to IL-2 in the absence of IL-4 drives CD4+ Th cells towards Th1 function. Th2 cells support humoral immunity by producing IL-4, 5, 10.-Th1 cells support cellular immunity by producing IL-2 and IFN-gamma. -IFNgamma produced by activated Th1 cells inhibits the activation of Th2 cells-TGFbeta produced by activated B cells inhibits the activation of Th1 cells (cross inhibition between the humoral and cellular arms)

-T-cell activation is solely dependent on the interaction with mature APCs.

-Naive T-cells can only be activated by weak signaling from APCs.

-IL-4 drives CD4+ Th cells towards Th1 function while IL-2 exposure leads to Th2 function.
