We have mast cells in the stomach wall. Somastatain-which is produced from d cells in the stomach wall is a known mast cell activator. We also know stress-in particular substance p and CRH also cause mast cells to spill contents. Histamine which we know is a chemical constantly released.
The mast cells create this reaction by releasing chemicals, called chemotactic factors, that then attract many other inflammatory cells to the site. These cells include: eosinophils, neutrophils, and lymphocytes. Once theyâve arrived, each one of these cells contributes to the late phase of the allergic response. Eosinophils generate chemicals similar to those made by mast cells, as well as release more generally toxic substances that irritate the body.
