histamine can be released into the body as a result of a bite or an allergy. You may see signs of histamine being released in the body as a result of a bite. you will see the area become red and inflamed (erythema and oedema). If you have a bite or a sting and you are severly allergic to it (ie, a bee sting) you may suffer from an anaphalactic shock. in this instance the person should be immediatly treated with adrenalin.
They are released by basophils and mast cells in nearby connective tissue.
Histamine is produced by the body in response to allergens, and antihistamine drugs work by blocking the action of histamine in the body.
There are a number of chemicals, I assume you are interested in the main one, which is Histamine. Histamine triggers the inflammatory response and increases the permeability (the ability to pass through the wall) of the capillaries to white blood cells to fight foreign bodies (the allergen) in the body. When you get hay fever you go to the chemist to get an anti-histamine so as to stop the body's normal response to the allergen like running nose or watery eyes.
Histamine is the primary effector substance released by the mast cell in response to an allergy. When you have an allergy to something, you exhibit certain common symptoms. Sneezing, itchy and watery eyes, an itchy throat, a runny nose, and itchy rashes are all possible symptoms of an allergy. and the best way to combat these symptoms is to use an antihistamine that, as the name suggests, blocks the amount of histamine that is produced by the body
Histamine is released by basophils and mast cells in near by connective tissue which is an immune response to foreign pathogens.
Mast cells and basophils release histamine. When histamine is released, it causes blood vessels to dilate, which can lead to symptoms such as redness and swelling (inflammation), increased mucus production, and smooth muscle contraction, resulting in symptoms like itching and bronchoconstriction.
Mast cells are the connective tissue cells that produce histamine in response to various stimuli, such as allergens or injury. Histamine is a key mediator of inflammation and allergic responses in the body.
Purpose of histamine is to trigger immune response for foreign bodies
Mast cells produce histamine in response to allergies. Histamine is a key inflammatory substance that contributes to allergy symptoms such as itching, swelling, and redness. When allergens are detected, mast cells release histamine, leading to an inflammatory response that helps the body fight off perceived threats.
Mast cells are the primary cells that produce and release histamine. Histamine is stored in granules within mast cells and is released in response to allergens and other triggers, leading to symptoms of allergy such as itching, sneezing, and swelling.
It's general biochemical name is an Antigen - anti = against and gen = genesis.
Basophils are the granulocytes that produce and release histamine. Histamine is involved in the inflammatory response and allergic reactions.
