AM (-35%) of Mecp2-/y mice and to a lesser extent in the PG (-11%) and AM (-18%) in Mecp2+/- mice. We evaluated in vivo the chemoreflex sensitivity of Mecp2-/y mice using whole-body plethysmography to record the breathing of Mecp2-/y mice in normoxia and in response to acute hypoxia (10% O(2)). Our results show that the hypoxic ventilatory response is significantly increased in Mecp2-/y mice (+50%) demonstrating in vivo disturbances of the chemoafferent pathway. In conclusion, . et al. 0 our results offer new insights to better understand the mechanisms leading to autonomic dysfunction in RS.;05/12/2008;07/03/2016 15:17;23/06/2020 08:44;;82-86;;1;447;;Neurosci.
