Interferon-gamma / IFN-γ

Understand the connection

Interferon-gamma, or IFN-γ, is a type II interferon produced by immune cells including T cells and natural killer cells. It helps activate macrophages and organize defense against infection.

Dr. Purser connects the Th1 immune response with macrophage activation, antigen presentation, and inflammation. He discusses the interaction of IFN-γ with TNF-alpha, barrier tissues, and oxidative stress rather than treating any one cytokine as the whole explanation.
