1. Effects of Listeria monocytogenes on IFN-γ Responses by CD4⁺ and CD8⁺ Cells

NOTE: This procedure describes how to measure IFN-γ production by splenic CD4⁺ and CD8⁺ T effector cells harvested at the time of the peak of the adaptive immune response (~ 7 d post-infection) using two methods: (1) flow cytometry to measure IFN-γ (Interferon-gamma) by CD4⁺ and CD8⁺ cells by intracellular cytokine staini....
