Experimental Charcot-Marie-Tooth type 1A: A cDNA microarrays analysis

These results are relevant to reveal the molecular function of PMP22 and the pathogenic mechanism of CMT1A. In particular, finding a specific reduction of cntf expression in CMT1A Schwann cells suggests that overexpression of pmp22 significantly affects the ability of Schwann cells to offer a trophic support to the axon, which could be a factor, among other, responsible for the development of axonal atrophy in human and experimental CMT1A.
