Basophils are the granulocytes that produce and release histamine. Histamine is involved in the inflammatory response and allergic reactions.
Histamine
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.
Actualy white blood cells release histamine.
Histamine is released by basophils and mast cells in near by connective tissue which is an immune response to foreign pathogens.
Basophils primarily release histamine and other pro-inflammatory molecules in response to allergens. They do not secrete hormones like the endocrine glands, such as the pituitary gland, which releases hormones like growth hormone or thyroid-stimulating hormone.
They are released by basophils and mast cells in nearby connective tissue.
Histamine release can be stimulated by various triggers such as allergens, physical injury, stress, and certain types of drugs. When the immune system detects these triggers, it releases histamine as part of the inflammatory response.
Histamine is the non-hormonal chemical messenger secreted by mast cells that contributes to the inflammatory response. It causes vasodilation, increased vascular permeability, and smooth muscle contraction, leading to symptoms like redness, swelling, and itching.
Macrophages are the primary cells responsible for initiating the inflammatory response. They recognize and engulf pathogens or debris, releasing cytokines that signal other immune cells to join the response. Additionally, mast cells are also involved in the early stages of inflammation by releasing histamine and other inflammatory mediators.
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.
The release of inflammatory mediators such as histamine, prostaglandins, and nitric oxide causes arterioles in the damaged area to dilate. This dilation increases blood flow to the damaged tissues, bringing in immune cells and nutrients to aid in the healing process.
