Abstract

Excessive inflammation is considered as a critical factor in many human diseases, including cancer, obesity, type II diabetes, cardiovascular diseases, neurodegenerative diseases and aging. Compounds derived from botanic sources, such as phenolic compounds, have shown anti-inflammatory activity in vitro and in vivo. Recent data suggest that polyphenols can work as modifiers of signal transduction pathways to elicit their beneficial effects. These natural compounds express anti-inflammatory activity by modulation of pro-inflammatory gene expression such as cyclooxygenase, lipoxygenase, nitric oxide synthases and several pivotal cytokines, mainly by acting through nuclear factor-kappa B and mitogen-activated protein kinase signalling. This review will discuss recent data on the control of inflammatory signalling exerted by some dietary polyphenols contained in Mediterranean diet. A clear understanding of the molecular mechanisms of action of phenolic compounds is crucial in the valuation of these potent molecules as potential prophylactic and therapeutic agents.

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here

Cardiovascular Inflammation

Inflammation plays a significant role in the development of cardiovascular diseases, an understanding of these endogenous processes is critical for evaluating the risks and potential treatment strategies. Discover the latest research on cardiovascular inflammation here.
