T Helper Cells аnd Their Rоles (Bruskо) (A) Nаïve T cells fоllow а highly predictable program in response to TCR stimulus and costimulation provided in vitro. Identify a molecular and/or cellular feature at three key points along this activation program – within hours, at 1-day post activation, and at several days post activation – that you would use to identify the T cell response to stimulus. (4 points) (B) Name the 4 major T helper subsets and an effector cytokine they produce. (4 points) (C) Briefly describe an example of T cell plasticity and explain why this phenomenon provides an advantage. (2 points)
