PG - F1231-42 LID - 10.1152/ajprenal.00557.2012 [doi] AB - Tumor necrosis factor-alpha (TNF-alpha) is a pleiotropic cytokine that becomes elevated in chronic inflammatory states such as hypertension and diabetes and has been found to mediate both increases and decreases in blood pressure. High levels of TNF-alpha decrease blood pressure, whereas moderate increases in TNF-alpha have been associated with increased NaCl retention and hypertension. The explanation for these disparate effects is not clear but could simply be due to different concentrations of TNF-alpha within the kidney, the physiological status of the subject, or the type of stimulus initiating the inflammatory response. TNF-alpha alters renal hemodynamics and nephron transport, affecting both activity and expression of transporters. It also mediates organ damage by stimulating immune cell infiltration and cell death. Here we will summarize the available findings and attempt to provide plausible explanations for such discrepancies.
