Polymorphonuclear Overview
Polymorphonuclear leukocytes, commonly known as PMNs, are a type of white blood cell that plays a crucial role in the body's immune response. PMNs are part of the innate immune system and are among the first responders to infection or injury. These cells are characterized by their multilobed nuclei, giving them their distinctive appearance under a microscope.
One of the key functions of polymorphonuclear leukocytes is to engulf and destroy pathogens through a process called phagocytosis. When a PMN encounters a foreign invader such as bacteria or fungi, it will engulf the microbe and release potent antimicrobial substances to neutralize the threat. This action helps to prevent the spread of infection and promote healing.
Types of Polymorphonuclear Cells
There are three main types of polymorphonuclear leukocytes: neutrophils, eosinophils, and basophils. Neutrophils are the most abundant type of PMN and are highly effective at combating bacterial infections. Eosinophils are involved in the immune response to parasites and allergic reactions. Basophils release histamine and other inflammatory mediators in response to allergens.
These polymorphonuclear cells are produced in the bone marrow and released into the bloodstream, where they circulate until they are needed at the site of infection or inflammation. The presence of an elevated number of PMNs in the blood, known as a "left shift," can indicate an active infection.
Overall, polymorphonuclear leukocytes play a critical role in the body's defense against pathogens and are essential for maintaining immune health. Understanding the function and significance of these white blood cells can provide valuable insights into the body's immune response and how it protects itself from harm.
