Directional Mast Cell Degranulation of TNF into Blood Vessels Primes Neutrophil Extravasation

Published: Jan 1, 2020
Abstract
Tissue resident mast cells (MCs) rapidly initiate neutrophil infiltration upon inflammatory insult, yet the molecular mechanism is still unknown. Here, we demonstrate that MC-derived TNF is crucial for neutrophil extravasation to sites of sterile skin inflammation by promoting intraluminal adhesion and crawling. Strikingly, MC-TNF directly primes circulating neutrophils via TNFR1, while being dispensable for chemokine production and endothelial...
