Polymorphonuclear leukocytes (PMNs) are a type of white blood cell (WBC) that include neutrophils, eosinophils, basophils, and mast cells. PMNs are a subtype of leukocytes, which protect the body against infectious organisms. PMNs are also known as granulocytes. They play a central role in the innate … See more The term "polymorphonuclear" describes the varied shapes and sizes of the cells' nucleus (the part of the cell that contains chromosomes). PMNs' nuclei have two or three lobes with deep divisions. This dynamic is unlike … See more PMNs, other types of white blood cells, red blood cells, and platelets develop from hematopoietic stem cellsin the bone marrow. Hematopoietic stem cell precursors are those cells committed to forming a new kind of … See more Each PMN has a slightly different role in health, although there is some overlap. For example, while a healthy PMN response can fight infection, an … See more PMNs are part of the non-specific innate immune system.4That means that they similarly treat all intruders.

WebLeukotriene B 4, formed in inflammatory cells such as PMNs and monocytes, is a potent stimulator of PMN activity. It induces margination at endothelial cells, degranulation, diapedesis, and superoxide generation and acts synergistically with prostaglandin E 2 to enhance vascular permeability.
