Brief description of the research:

We work on the basic mechanisms underlying oxygen sensing by cells. We pay special attention to unravel the molecular mechanisms of acute oxygen sensing by specialized chemoreceptor cells in the carotid body, arterial smooth muscle and other locations. In addition, we study the role of oxygen, mitochondria, and metabolism on neurogenesis and the protective action of neurotrophic factors in neuronal pathways.
