Key Points
-Mast cell activation syndrome exhibits diverse clinical presentations, often overlapping with symptoms of other illnesses while being underrecognized for its role in hyperinflammation, including viral infections.
-Mast cells store and release potent pro-inflammatory cytokines implicated in various physiological and pathological processes that are associated with chronic illnesses and autoimmune conditions, while its inhibitors have shown efficacy in treating autoimmune and inflammatory disorders.
Abstract
Increasing evidence underscores the vital significance of diverse mast cell mediators in inflammatory illness, yet diagnostic criteria for mast cell activation syndrome still focus predominantly on a solitary mediator, tryptase. Therapeutic interventions, conversely, tend to prioritize histamine, prostaglandins, and leukotrienes. This article, via a review of both experimental and clinical findings, spotlights the mechanisms of action of an important mast cell mediator - tumor necrosis factor (TNF), and elucidates the intricate linkages between mast cell dysfunction, chronic illness, and autoimmunity.
After providing an overview of the role of mast cell-derived TNF in inflammatory illnesses and viral infections, we hypothesize the interplay between mast cell-derived TNF and mitochondrial dysfunction, microglial activation, and the hypothalamic-pituitary-adrenal axis and the pathways of action on mast cells of treatments such as high-dose melatonin and low-dose naltrexone.
