Physiological and pathological ageing of nervous control of respiration: study in wild and transgenic mice

Abstract

New issues are emerging in the field of Health care due to ageing of the population and the alarming development of Alzheimer’s Disease (AD). In healthy or pathological living being, very few studies are dealing with the ageing of the respiratory nervous control, in spite of the crucial role of respiration for brain oxygenation. This thesis presents translational research performed in mice to examine the physiological and pathological ageing of the respiratory nervous control. In mice from two transgenic strains, recognized models for AD and Rett syndrome, we describe the development of drastic respiratory neuropathologies leading to premature death. In the AD mouse model, we show for the first time that brainstem tauopathy triggers dysfunctions of the upper airways, impairs vocalization and alters respiration and respiratory control. In addition, our work suggests a deleterious effect of anaesthesia for AD and identifies new therapeutic strategies. This mouse research could well contribute to significant improvements in AD care.
