What is causing the allergy? Different allergies have different triggers. Recently scientists from Virginia Commonwealth University have found a possible cause.
Mast cells are specialized cells that react to allergy-causing agents by releasing substances that trigger the body's allergic response, leading to conditions like asthma and hives. Among the molecules released by mast cells that participate in the allergic response is sphingosine-1-phosphate. This molecule is also implicated in cancer.
