- (RSS) (BioRxiv All) Aging changes the underlying mechanism of JAK2 modulation in neutrophil function: Janus Kinase 2 (JAK2) has been linked to various neutrophil functions, but the intracellular mechanisms underlying its modulation are unknown. Neutrophils are essential cells for host defense. Neutrophil effector functions include migration, reactive oxygen species (ROS) production, degranulation, and neutrophil extracellular trap (NET) formation.… https://www.biorxiv.org/content/10.1101/2025.04.21.649782v1?rss=1&utm_source=dlvr.it&utm_medium=mastodon #BioRxiv #MassSpecRSS
