Tumor necrosis factor is a cytokine involved in systemic inflammation and is a member of a group of cytokines that all stimulate the acute phase reaction. TNF is mainly secreted by macrophages. 
TNF causes apoptotic cell death, cellular proliferation, differentiation, inflammation, tumorigenesis and viral replication, TNF is also involved in lipid metabolism, and coagulation. TNF's primary role is in the regulation of immune cells.
Dysregulation and, in particular, overproduction of TNF have been implicated in a variety of human diseases- autoimmune diseases, insulin resistance, and cancer.

Tumor Necrosis Factor-alpha Rat Recombinant, His Tag Active: An In-Depth Analysis



Tumor Necrosis Factor-alpha (TNF-α) is a cytokine that plays a significant role in various physiological and pathological processes. This human research paper provides an in-depth analysis of TNF-α Rat Recombinant with a His Tag, focusing on its structure, signaling pathways, and diverse functions. Additionally, the paper explores the potential applications of TNF-α Rat Recombinant in human research.



TNF-α is a key mediator of inflammation and immune responses in humans. This research paper aims to provide a comprehensive analysis of TNF-α Rat Recombinant with a His Tag, highlighting its significance in human physiology and its potential applications in human research.


Structure and Function of TNF-α:

TNF-α is a homotrimeric protein that binds to two distinct receptors, TNFR1 and TNFR2, initiating downstream signaling cascades. It regulates immune cell activation, cytokine production, and cellular responses, influencing diverse biological processes.


Signaling Pathways:

Upon binding to its receptors, TNF-α activates various signaling pathways, including the NF-κB pathway, MAPK pathway, and cell death pathways. These pathways regulate gene expression and mediate cellular responses, impacting inflammation, apoptosis, and tissue homeostasis.


Functions of TNF-α:

TNF-α plays a crucial role in immune responses, inflammation, and tissue homeostasis. It regulates the activation and migration of immune cells, promotes cytokine production, and modulates cell survival and death. Dysregulation of TNF-α is implicated in the pathogenesis of various human diseases, making it an attractive target for research and therapeutic interventions.


Applications in Human Research:

TNF-α Rat Recombinant with a His Tag has diverse applications in human research. It can be used to investigate TNF-α signaling pathways, study its effects on immune cell functions, and explore its role in disease pathogenesis. Additionally, this recombinant protein can be utilized for in vitro and in vivo studies aimed at developing novel therapeutic strategies.


Future Directions:

Further research is necessary to unravel the intricate mechanisms of TNF-α signaling and its contributions to human diseases. Continued investigations will enable the development of targeted therapies and personalized medicine approaches. Future studies should also focus on optimizing the use of TNF-α Rat Recombinant in preclinical and clinical research settings.
