Laboratory of Molecular and Cellular Physiology. Coordinator: Ferroni

The laboratory deals with identification of the role ionic channels play in some physiological and pathophysiological processes. Some research activities aim to characterize ionic mechanisms controlling homeostatic functions of the astroglial and neuronal cells. The other part of studies is dedicated to identify the ionic channels involvement in pathogenetic mechanisms of genetic diseases such as Anderson-Fabry disease. These projects are being developed in animal models, rats and mice as well as in cell lines or cells procured by the biopsy of the human skin. All the studies mentioned come from the techniques used in molecular and cellular biology, cellular electrophysiology and microfluorimetry

Research themes

Cerebral homeostatic mechanism in physiology and physiopathology

These studies analyze cellular and molecular mechanisms that are essential for the homeostatic control of astroglial cells in physiological conditions and their regulation in pathophysiological situations.

Channelopathy in glial and neuronal cells

The principal aim of this part of the research is to determine the pathogenetic role of the altered protein channel expression in the glial and neuronal cells in some of the chronic diseases of the central nervous system.

Expressions and functions of the ionic channels included in the neuropathic pain of the Fabry disease.

The principal aim of this part of the research is to study the role of the diverse receptors/ionic channels included in the nociceptive processes participating on neuropathic pain of the lysosomal storage disease defined as the Fabry disease.
