Cancer And Psoriasis can be aggravated by "Allergy Cells"

|

The body's mast cells are mainly associated with allergic reaction in the way they release histamine and other inflammatory substances. However, researchers at Karolinska Institutet have now demonstrated how the mast cells can also contribute to diseases like psoriasis and cancer.

Mast cells are most known for their association with allergic reactions, as they act like microscopic "bombs" to trigger the release of a number of substances that give rise to the classic allergic symptoms, such as swelling, congestion and itching. The explosive reactions are activated when an allergen (such as pollen particles) binds to receptors on the surface of the mast cell, which then opens and secretes part of its contents.
