TNF-a, which first emerges during the inflammatory response of biological organisms, plays a crucial role as an immune inflammatory mediator in the body. It possesses the ability to stimulate the acute phase reaction of cells, enabling a response to stimuli such as infection factors or tissue damage. Upon activation, TNF-a circulates throughout the biological organism, influencing the characteristics of vascular endothelial cells, regulating metabolic activity in various tissues, and inducing local coagulation. Furthermore, it displays cytotoxic activity and promotes activation of neutrophils and lymphocytes [Reference]
