This article outlines a study on mice that tests the effects of the SSRI fluoxetine on IgE-induced activation of mast cells. It discusses how fluoxetine suppresses mast cell activation and ATP secretion, which amplifies IgE responses. The article concludes by suggesting that fluoxetine is a promising candidate for repurposing allergy treatment.
