Restoration of SMN in Schwann cells reverses myelination defects and improves neuromuscular function in spinal muscular atrophy [PDF]
, 2016 Spinal muscular atrophy (SMA) is a neuromuscular disease caused by low levels of SMN protein, primarily affecting lower motor neurons. Recent evidence from SMA and related conditions suggests that glial cells can influence disease severity.
