Gene | Role(s) in neutrophil homeostasis |
---|---|
CD177 | NB1 is a glycosylphosphatidylinositol (GPI)-anchored glycoprotein expressed exclusively by neutrophils, metamyelocytes and myelocytes |
SOD1 | The SOD1 gene encodes superoxide dismutase-1, a major cytoplasmic antioxidant enzyme that metabolizes superoxide radicals to molecular oxygen and hydrogen peroxide. CD177Â is upregulated in various inflammatory settings, including bacterial infections. Heterophilic PECAM1/CD177Â interactions affect the phosphorylation state of PECAM1, as well as endothelial junction integrity and neutrophil transmigration |
CD64 | CD64 is the gene encoding human FcγRI (FCGR1), a glycoprotein that is constitutively expressed on human monocytes and macrophages and that plays a pivotal role in the immune response |
FCGR3B | The Fc receptor with low affinity for IgG (CD16b) encodes a glycosylphosphatidylinositol (GPI)-anchored protein that is expressed constitutively by neutrophils |
ELANE | Neutrophil elastase is a serine protease of neutrophil and monocyte granules, with key physiologic roles in innate host defense |
MPO | Myeloperoxidase is a lysosomal protein located in the azurophilic granules of polymorphonuclear leukocytes and monocytes. MPO is responsible for microbicidal activity against a wide range of organisms |
LYZ | Lysozyme catalyzes the hydrolysis of certain mucopolysaccharides of bacterial cell walls |
CEACAM8 (CD67) | Neutrophil surface protein that is attached to the membrane via a glycosylphosphatidylinositol anchor. In neutrophils, the CEACAM8 gene is primarily detected in the secondary cytoplasmic granules, but it can also be found in lower amounts on the plasma membrane. The amount of surface CD67 is upregulated upon granulocyte activation |
CD62L | Homing receptor for lymphocytes to enter secondary lymphoid tissues via high endothelial venules |
