STAT3 controls myeloid progenitor growth during emergency granulopoiesis.
Granulocyte colony-stimulating factor (G-CSF) mediates "emergency" granulopoiesis during infection, a process that is mimicked by clinical G-CSF use, yet we understand little about the intracellular signaling cascades that control demand-driven neutrophil production. Using a murine model with conditional deletion of signal transducer and activator of transcription 3 (STAT3) in bone marrow, we i...

متن کاملSTAT3 governs distinct pathways in emergency granulopoiesis and mature neutrophils.
Granulocyte colony-stimulating factor (G-CSF) is essential for the host response to bacterial infection by controlling neutrophil production in the bone marrow. The G-CSF receptor (G-CSFR) activates the Jak/STAT pathway, although little is understood about how these signals regulate basal and stress-induced granulopoiesis. We examined STAT3 function in granulocytes using a bone marrow condition...
متن کاملBAFF-secreting neutrophils drive plasma cell responses during emergency granulopoiesis
Prolonged infections or adjuvant usage can trigger emergency granulopoiesis (EG), leading to dysregulation in neutrophil blood counts. However, the impact of EG on T and B cell function remains largely unknown. In this study, to address this question, we used a mouse model of neutropenia and studied immune activation after adjuvant administration. The initial neutropenic state fostered an envir...
متن کاملStat3 and CCAAT enhancer–binding protein β (C/ebpβ) activate Fanconi C gene transcription during emergency granulopoiesis
Interferon consensus sequence-binding protein (Icsbp) is required for terminating emergency granulopoiesis, an episodic event responsible for granulocyte production in response to infections and a key component of the innate immune response. Icsbp inhibits expression of Stat3 and C/ebpβ, transcription factors essential for initiating and sustaining granulopoiesis, and activates transcription of...
