Neutrophil homeostasis and periodontal health in children and adults.

ABSTRACT: This review summarizes the current state of knowledge on neutrophil basic biology and discusses how the breakdown of neutrophil homeostasis affects periodontal health. The homeostasis of neutrophils is tightly regulated through coordinated bone marrow production, release into the circulation, transmigration to and activation in peripheral tissues, and clearance of senescent neutrophils. Dysregulation of any of these homeostatic mechanisms at any age can cause severe periodontitis in humans and animal models. Accordingly, both impaired and excessive neutrophil activity (in terms of numbers or immune function) can precipitate periodontitis. Neutrophil defects of congenital origin (e.g., congenital neutropenia, leukocyte adhesion deficiency, and Chediak-Higashi syndrome) are associated with c
