Research areas

The scientific work undertaken by our group is related to three fundamental areas:

  • Cellular mechanisms of oxygen sensing.

    Within this area we investigate the nature of the sensors that mediate acute responses to hypoxia, especially in the carotid body and the adrenal medulla. We also investigate the regulation of genes (particularly those that code for ion channels) for chronic hypoxemia (maintained or intermittent). Within the general subject of oxygen homeostasis, we collaborate with other IBIS groups with a view to determining the possible role of aquaporins as oxygen channels. This area of research is related to pathologies derived from cerebral ischaemia or to those that appear in patients with chronic obstructive pulmonary disease or other respiratory alterations.
  • Neurodegeneration and neuroprotection in Parkinson's disease.

    We study the mechanisms of cell death in models of Parkinson's disease by means of the generation of genetically modified animals (transgenic and "knock out" animals). In parallel, the way in which the intrastriatal transplants of cells producing dopamine and neurotrophic factors (for example, cells of the carotid body) slow down the progression of Parkinson's disease is investigated. Within this field, the expansion of the adult carotid body from stem cells described in this organ, and the relation between the growth of cells of the carotid body and its tumour-like transformation, are the subject of on-going research. The clinical objective of this research area is to identify new therapeutic targets for Parkinson's disease and to improve cell therapy techniques applicable to this disease. In collaboration with other IBIS groups in this area, we also aim to better understand the mechanism underlying the genesis of paragangliomas.
  • Pathophysiological mechanisms of hypertension and vascular spasm.

    In collaboration with other IBIS groups we are investigating the role of calcium channels as metabotropic mediators in vascular contractility. Within this area, we also study the regulation of the expression of ion channels by oxygen, especially the T-type calcium channel and the beta1 subunit of the maxi-K channel. The association between intermittent hypoxia, the expression of ion channels in vascular smooth muscle, and vascular risk in patients with sleep apnoea also forms part of our research endeavours.
