WebImmunostaining of tissue sections indicates that neurons, oligodendrocytes, and nonmyelinating Schwann cells contain neurofibromin while astrocytes and myelinating Schwann cells do not. These results suggest a function for neurofibromin in the normal nervous system. WebOligodendrocytes select axons with diameters above 0.2 lm[171]. The molecular cues for this recognition remain unknown. In the peripheral nervous system, the critical axonal signal for myelination by Schwann cells is provided by neuronal neuregulin-1 (NRG1) type III, interacting with glial ErbB receptors, and it was thought for
