🧬 Rethinking Neutrophils: From Lone Cells to Living Systems 🧠⚔️   For over a century, neutrophils were seen as short-lived foot soldiers of immunity. This new Cell review reframes them as something far more interesting: a coordinated, adaptive collective .   ✨ Key ideas: • Short-lived cells, long-term memory • Two compartments: granulopoietic + mature • Plastic, circadian, tissue-adaptive behav...

⏰🫀 Does the heart care about the time of day? Yes—profoundly.   A new study in the Journal of Experimental Medicine reveals a circadian checkpoint in neutrophils that determines how much damage occurs after myocardial infarction. Morning ischemia triggers more injury, while nighttime CXCL12–CXCR4 signaling reprograms neutrophils , relocating them into the infarct core and sparing healthy myocard...
