histamin release

1 answer

Histamine release is the process by which histamine, a compound produced by cells in the immune system, is released into the bloodstream in response to allergens or other triggers. Histamine release can lead to a variety of allergic reactions, including itching, hives, nasal congestion, and more severe symptoms such as anaphylaxis. This process is a key component of the body's immune response, but excessive or misdirected histamine release can cause harmful effects. Antihistamine medications are often used to block the effects of histamine and reduce allergic symptoms.
