New Paper! How zebrafish control the production of newborn neurons after injury

A fluorescence micrograph showing macrophages (cyan) surrounding the spinal cord (magenta) during spinal cord regeneration in a larval zebrafish.

Alberto’s paper examining how the rate of production of newborn neurons is controlled by microglia after spinal cord injury was accepted at PLOS Biology! Microglia use sema4ab to signal to both neural stem cells and fibroblasts to rate-limit the number of new neurons which are born to replace those lost after injury. Check out the paper here!
