Mast cell activation syndrome (MCAS) is a condition that occurs when the mast cells in your body release too much of a substance that causes allergy-like symptoms. Mast cells are part of your ...

Mast cells are essential to the immune system and release histamine in response to allergens. However, mastocytosis can occur when mast cells accumulate in excess. Mastocytosis can increase a ...

Urticaria pigmentosa happens when the body's mast cells release histamines in response to a perceived threat to the immune ...

Allergy cells' hidden secret Mast cells trap and use living neutrophils during allergic reactions Date: August 2, 2024 Source: Max Planck Institute of Immunobiology and Epigenetics Summary: Known ...

Known for their role in allergic reactions, mast cells have long been recognized as key players in our immune system. When they encounter allergens, they release chemicals that trigger typical ...

Antigen-specific IgE released by B cells binds the receptor, initiating a cascade of events that leads to mast cell degranulation and release of inflammatory modulators, the most important in this ...

When triggered, mast cells release chemicals like histamine and heparin, which can cause signs and symptoms similar to an allergic reaction. In systemic mastocytosis, mast cells multiply ...

Mast cells in the dura mater, which release proinflammatory cytokines and are linked to the MrgprB2 receptor, are implicated in withdrawal headaches. Considering alcohol's effect on mast cells ...

Mast cell activation syndrome is a condition that causes mast cells to release an inappropriate amount of chemicals into your body. This causes allergy symptoms and a wide range of other symptoms.

The researchers found that mast cells release leukotriene B4, a substance commonly used by neutrophils to initiate their own swarming behavior. By secreting this substance, mast cells attract ...

Mast cell activation syndrome, or disease (MCAS), is a condition that causes mast cells to release these substances too frequently, resulting in severe allergic reactions. After detecting an ...
