Mast Cells: Important Role in the Immune System

A mast cell is a blood cell belonging to the leukocytes.

Mast cells play an important role in the human body's immune system, for example, in wound healing and in the defense against pathogens.

They also come into play in the development of allergies and allergic reactions. The mast cell contains, among other things, histamine as a messenger substance, which is released when irritated, e.g., by an allergen. In people with neurodermatitis, this could trigger a new flare-up with redness and itching, for example.
