Mechanism of action

IFN-γ-1b is a recombinant cytokine that binds to interferon-gamma receptors on immune cells, particularly macrophages, enhancing their antimicrobial and antitumor activity. It increases expression of MHC molecules and activates natural killer cells and T cells, strengthening both innate and adaptive immune responses. This mechanism makes it useful in conditions characterized by impaired immune function or chronic infections.
