Human neutrophils (polymorphonuclear leukocytes) are key to innate immunity, fighting infection via phagocytosis and releasing antimicrobial compounds. Their regulated removal through apoptosis aids in resolving inflammation.
Area of Science:
- Immunology
- Cell Biology
Background:
- Polymorphonuclear leukocytes (PMNs), or neutrophils, are crucial innate immune cells.
- They are rapidly recruited to infection sites and primed for enhanced microbicidal activity.
Purpose of the Study:
- To provide an overview of human neutrophils' role in innate immunity.
- To summarize recent advances in neutrophil biology.
Main Methods:
- Review of existing literature on neutrophil function and regulation.
Main Results:
- Neutrophils utilize phagocytosis, reactive oxygen species, and granule components to kill pathogens.
- Neutrophil homeostasis is tightly regulated by apoptosis, which is accelerated post-bacterial phagocytosis.
Conclusions:
- Neutrophil apoptosis is vital for infection resolution and inflammation control.
- Understanding neutrophil biology is essential for innate immunity research.

Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

Introduction to Innate and Adaptive Immunity
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
