Immune cells called macrophages help heal nerve injury
Bundles of nerve cells, or neurons, carry messages around our bodies – but injury can cut off this communication, taking away control and sensation. In these mouse neurons, though, a severed nerve is healing – artificially-coloured Schwann cells (green) surround neurons as they extend across the wound. This bridge-building is encouraged by a surprising ally – white blood cells called macrophages. Usually found chomping pathogens during an infection, here macrophages pump out a protein called
