Pinpointing brainstem mechanisms responsible for autonomic dysfunction in Rett syndrome:therapeutic perspectives for 5-HT1A agonists [PDF]

, 2014
Rett syndrome is a neurological disorder caused by loss of function of methyl-CpG-binding protein 2 (MeCP2). Reduced function of this ubiquitous transcriptional regulator has a devastating effect on the central nervous system.
