Role of Interferon-Gamma (IFN-γ) in Pathophysiology and Management of Deep Vein Thrombosis

Immune cells like neutrophils, monocytes/macrophages, and lymphocytes play key roles in the development, progression, and resolution of deep vein thrombosis (DVT) by contributing to inflammation, coagulation, and fibrinolysis. IFN-γ, a cytokine mainly secreted by natural killer (NK) and T cells, is a critical factor in DVT pathogenesis. It links immune responses to coagulation activation by promoting endothelial activation, leukocyte recruitment, cytokine release, and coagulation imbalance. Its strong pro-inflammatory and prothrombotic effects make IFN-γ a promising target for DVT treatment beyond standard anticoagulants. Exploring ways to block IFN-γ signaling or its downstream effects could open doors to novel therapies for DVT, aiding in resolution and preventing post-thrombotic complications. This review delves into DVT pathophysiology, diagnostics, and management, emphasizing the importance of targeting immune cells and IFN-γ to advance treatment options.
