In a new study, researchers administered a single injection to tissues surrounding the spinal cords of paralyzed mice. Just four weeks later, the animals regained the ability to walk.

Shp2 is a phosphotyrosine phosphatase; its job is to remove phosphates from protein tyrosine residues, aiding and abetting signal communications within cells.
