About My Guest

My guest for this episode is Dr. Theo Theoharides.  Dr. Theo Theoharides, PhD, MD has studied the regulation of mast cell activation and its role in neuroinflammatory disease for over 30 years. He holds a Masters in Neuroimmunology, a PhD in Pharmacology, and an MD from Yale University.  He was the first to report that mast cells can secrete specific mediators selectively without degranulation, regulate blood-brain-barrier permeability, stimulate microglia, be activated by corticotropin-releasing hormone (CRH) secreted under stress to release VEGF selectively, be activated by synergistic action of CRH and neurotensin, be activated by IL-33 and substance P synergistically to secrete the pro-inflammatory cytokine TNF, secrete mitochondrial DNA extracellularly that is mistaken by the body as a pathogen resulting in inflammatory reactions, and communicate with microglia and are involved in inflammation of the brain.  He discovered that mast cells are inhibited by certain natural flavonoids, especially luteolin and tetramethoxyluteolin.  He has published over 400 peer-reviewed papers and is in the top 5% of authors cited in pharmacological and immunological journals.  He is the developer of the well-known liposomal mast cell blocking nutritional supplement known as NeuroProtek and several other products.
