ArticleMyelin-associated glycoprotein inhibits axonal regeneration from a variety of neurons via interaction with a sialoglycoproteinFilbin, Marie T.Myelin-associated glycoprotein (MAG) is a potent inhibitor of axonal regeneration from both cerebellar neurons and adult dorsal root ganglion (DRG) neurons. In contrast, MAG promotes axonal growth from newborn DRG neurons. Here, we show that the switc . . .
