TNF-alpha

Tumor Necrosis Factor-alpha (TNF-α) is a pro-inflammatory cytokine involved in systemic inflammation and is part of the cytokine family that stimulates the acute phase reaction. It is primarily produced by activated macrophages, but also by a variety of other cells including lymphocytes, mast cells, and certain tumor cells. TNF-α plays a crucial role in the immune response to infection and is involved in the regulation of immune cells, apoptosis, and inflammation. Clinically, elevated TNF-α levels are associated with a range of inflammatory and autoimmune diseases such as rheumatoid arthritis, psoriasis, and inflammatory bowel disease. It is also implicated in the pathogenesis of certain cancers and metabolic disorders like obesity. TNF-α inhibitors are used therapeutically to manage these conditions, highlighting its significance as a biomarker for disease activity and treatment response. For athletes and biohackers, TNF-α is of interest due to its role in inflammation and recovery. Chronic low-grade inflammation, as indicated by elevated TNF-α, can impair recovery and performance. Monitoring TNF-α levels may help optimize training and recovery strategies. However, TNF-α levels can be influenced by various factors including infections, stress, and circadian rhythms. It is important to consider these confounders when interpreting TNF-α levels. Fasting and time of day may also affect results, as cytokine levels can fluctuate throughout the day.
