Granulocytes are a type of white blood cell that plays an important role in the body's immune system. They are part of the body's defense against infections and other diseases. Granulocytes are made up of granules, which are tiny particles that contain enzymes and other substances needed to fight off infections.
General Functions of Granulocytes
Granulocytes are the body's first line of defense against infection and disease. They recognize and attack foreign invaders, such as bacteria and viruses, and help activate other parts of the immune system. Granulocytes also play a role in the healing process after an injury.
Types of Granulocytes
There are three main types of granulocytes: neutrophils, eosinophils, and basophils. Neutrophils are the most common type of granulocyte and are responsible for destroying bacteria and other invading pathogens. Eosinophils help fight off parasites, allergens, and certain types of cancer cells. Basophils are involved in the body's response to allergens and help to release histamine, which causes inflammation.
Granulocyte Production
Granulocytes are produced in the bone marrow and are released into the bloodstream when needed. The production of granulocytes is regulated by the body's hormones and other signals. If the body detects an infection or other foreign invader, it will release more granulocytes into the bloodstream to fight off the infection.
The Role of Granulocytes in Disease
Granulocytes are important for fighting off infections and other diseases, but they can also be involved in the development of certain diseases. For example, too many granulocytes in the blood can lead to inflammation and other symptoms, such as fever, fatigue, and joint pain. Granulocytes can also be involved in the development of autoimmune diseases, such as lupus and rheumatoid arthritis.
