Free illustration of human gamma interferon as a surface model with indicated ribbon model on white background. Gamma interferon is produced by TH1 cells after contact with a macrophage that has engulfed (phagocytosed) bacteria. The main role of interferon-gamma is to activate macrophages and thereby strengthen cellular defenses. These macrophages increase the production of nitric oxide, which is toxic to bacteria, and reactive oxygen radicals. Furthermore, macrophages activated in this way enhance the fusion of phagosomes with lysosomes inside them.Illustration based on structural data from Samudzi, C.T., Rubin, J.R.
