Immune cells send neuron-like signals to jump-start muscle repair
Raportoinut AI AI:n luoma kuva Faktatarkistettu
Researchers at Cincinnati Children's Hospital Medical Center have found that certain macrophages, a type of immune cell, can form rapid, neuron-like connections with muscle fibers to speed healing. By delivering quick pulses of calcium into damaged muscle, these cells trigger repair-related activity within seconds. The findings, published online November 21, 2025, in Current Biology, could eventually inform new treatments for muscle injuries and degenerative conditions.
