neutrophil differentiation
Definition
Target type: biologicalprocess
The process in which a myeloid precursor cell acquires the specialized features of a neutrophil. [GOC:mah]
Neutrophil differentiation is a complex process that begins in the bone marrow with the commitment of hematopoietic stem cells (HSCs) to the myeloid lineage. This commitment is driven by a cascade of transcription factors, including PU.1, GATA-1, and C/EBPα, which regulate the expression of genes specific to the myeloid lineage.
Once committed to the myeloid lineage, HSCs undergo several stages of differentiation, progressing from a multipotent progenitor cell (MPP) to a common myeloid progenitor (CMP) to a granulocyte-monocyte progenitor (GMP) and finally to a myeloblast. During these stages, the cells acquire the ability to produce specific myeloid lineage-specific markers, such as CD34 and CD117, and begin to express genes involved in the production of granules and other neutrophil-specific components.
The myeloblast is the first identifiable committed neutrophil progenitor. These cells are characterized by their large size, high nuclear:cytoplasmic ratio, and the presence of primary granules, which contain enzymes such as myeloperoxidase, elastase, and cathepsin G. Myeloblasts undergo several rounds of mitosis and differentiation to become promyelocytes.
Promyelocytes are slightly smaller than myeloblasts and contain both primary and secondary granules. Secondary granules contain a variety of proteins, including lactoferrin, lysozyme, and collagenase. Promyelocytes further differentiate into myelocytes, which are smaller than promyelocytes and have a less prominent nucleus. Myelocytes are characterized by the presence of tertiary granules, which contain gelatinase and other enzymes involved in extracellular matrix degradation.
Myelocytes differentiate into metamyelocytes, which are smaller than myelocytes and have a kidney-shaped nucleus. Metamyelocytes are the last stage of neutrophil differentiation that can undergo mitosis. They continue to differentiate into band cells, which have a horseshoe-shaped nucleus. Finally, band cells differentiate into mature neutrophils, which have a segmented nucleus with two to five lobes.
Mature neutrophils are released from the bone marrow into the bloodstream where they circulate for a few hours before migrating to tissues. Neutrophils are highly specialized cells that play a critical role in the innate immune system. They are the first responders to infection and inflammation, and they are responsible for engulfing and destroying invading pathogens.
Neutrophil differentiation is a tightly regulated process that is influenced by a variety of factors, including cytokines, growth factors, and chemokines. Dysregulation of neutrophil differentiation can lead to a variety of diseases, including leukemia, neutropenia, and chronic inflammatory diseases. '
