A protein fragment called NEP1-40, or similar molecules, could allow damaged nerves to grow back after spinal injuries, stroke, multiple sclerosis or brain trauma.
The peptide blocks another, called Nogo-66, which stops that recovery. So, in rats at least, NEP1-40 promotes significant regrowth in cells of injured spine and cortex, report Stephen M. Strittmatter and colleagues of the Yale University School of Medicine in New Haven, Connecticut, in this week’s Nature (Vol. 417, No. 6888, 30 May 02, pp. 547-551).
