Basophil granulocytes
Histamine and heparin
Mast cells are the cell types that contain both histamine and heparin. Histamine is stored in their granules and plays a role in the immune response, while heparin is an anticoagulant that helps prevent blood clotting.
Basophil
mast cells
The Basophil is the leukocyte that releases histamine and other mediators of inflammation; contain heparin, an anticoagulant.
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.
yes along with Heparin (anticoagulant), Histamine (vasodilator) and bradykinin (pain mediator
mast cells
These granulocytes are mast cells, not the typically recognized granulocytes like neutrophils, eosinophils, and basophils. Mast cells are tissue-resident immune cells that play a key role in allergic reactions and inflammation. They release histamine and heparin upon activation, contributing to immune responses and the regulation of vascular permeability.
Histamine and heparin
Histamine is released by basophils and mast cells in near by connective tissue which is an immune response to foreign pathogens.
