Web20 nov. 2001 · Injections of NT3 inhibited myelin formation, and the removal of the endogenous NT3 enhanced myelination. These results demonstrate that BDNF and NT3 possess different modulatory roles in the myelination program of the peripheral nervous system and that their mechanisms of action are specific and highly regulated. WebMyelin-associated glycoprotein (MAG) is a glycoprotein that is specific to Schwann cells, which create myelin for nerve cells in the peripheral nervous system. Research through cloning of the rat MAG gene has shown that it is a type I transmembrane protein meaning that it contains domains both inside the cell membrane and outside the cell membrane. tere dham ka pani mere lagya balaji
