histamine
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
Basophils and mast cells are white blood cells that release histamine and promote inflammation. Histamine is an important mediator of the inflammatory response, causing vasodilation and increased vascular permeability to allow immune cells to reach the site of infection or injury.
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.
Basophils.
Basophils release histamine in response to the presence of microorganisms.
Basophils are circulating white blood cells that release histamine, but mast cells also do so.
Basophils release histamine and other chemicals that can help to attract other immune cells to the site of infection. Additionally, basophils can phagocytize pathogens and help initiate the inflammatory response in the body. However, basophils are not as efficient at directly killing germs as other immune cells like neutrophils or macrophages.
Both basophils and eosinophils are types of white blood cells involved in the immune response. Basophils release histamine and heparin to promote inflammation and help fight parasitic infections. Eosinophils primarily target parasites and allergens by releasing toxins and enzymes to kill them.
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.
permeability
Three types of granulocytic white blood cells are neutrophils, eosinophils, and basophils. Neutrophils are the most common type and play a key role in fighting bacterial infections. Eosinophils are involved in allergic reactions and parasitic infections, while basophils release histamine and are involved in inflammatory responses.
