Neutrophil Activation (Engager) (N/A)

Neutrophil activation refers to the process by which neutrophils are stimulated to perform their effector functions such as phagocytosis, degranulation, production of reactive oxygen species (ROS), and formation of neutrophil extracellular traps (NETs). The term "engager" in this context typically refers to molecules or receptors that trigger or mediate this activation upon engagement with specific ligands. Key receptors include Fcγ receptors, GPCRs, complement receptors like CRIg, and TLRs. Activation leads to downstream effects such as increased phagocytosis, ROS generation, and degranulation, mediated by signaling pathways involving Src kinases, PI3K/Akt, PLCβ/Ca²⁺/PKC, and MAP kinases. Regulation of neutrophil activation is critical to prevent excessive inflammation and tissue damage.
