Beschreibung

General description

Interferon gamma (IFNγ) is a dimerized soluble cytokine that is the only member of the type II class of interferons. IFNγ is secreted by T helper cells (specifically, Th1 cells), cytotoxic T cells (TC cells) and Natural killer (NK) cells. When combined with other inflammatory cytokines, evaluating the levels of IFNγ can be used as a diagnostic tool in patients with breast cancer or benign prostatic hyperplasia. A recent study evaluated the effect of a cancer vaccine given to patients with colorectal cancer, on the levels of plasma pro-inflammatory cytokines (including IFN-γ). The study concluded that patients achieving stable disease showed increasing levels of plasma inflammatory cytokines.
