Mast cells release histamines which will dilate small blood vessels during inflammation.
When mast cells degranulate, the release histamines
The cells that are most involved with allergic reactions are eosinophils, mast cells and basophils. An allergic reaction can be caused by anything and can produce itching, hives, nausea, sneezing and vomiting.
Mast cells degranulate to release histamine.
Basophils Mast cells contain histamine. When they encounter a foreign body, they splay themselves and release histamines which then cause swelling and surround the foreign body so other parts of the immune system can rid the body of the foreign invader. Antihistamines offer much comfort.
Mast cells release histamines which will dilate small blood vessels during inflammation.
An allergic reaction is triggered by later encounters with the same allergen, which promptly binds and cross-links the IgE antibodies on the surface of the mast cells and basophils. This event includes an enzymatic cascade that causes the mast cells and basophils to degranulate, releasing a flood of histamine and other inflammatory chemicals that together induce the inflammatory response typical of allergy. page 798 anatomy and phisiology eighth edition
Mast cells are involved in allergic reaction.
Both Heparin and Histamine are released by basophils and mast cells. These cells are very similar, but mast cells are found on mucous membranes (connective tissue) and basophils are white blood cells that travel in the blood in the circulatory system.
