• In this way, Dr. Rodolfo Madrid, from the Faculty of Chemistry and Biology, refers to the Conicyt  funds granted for implementing a research ring that will join top scientists. The challenge is to study the physiological role of the TRP ion channels involved in detecting thermal and pain stimuli, among many other physiological processes. Knowing how these channels work may allow the development of treatments for attacking diseases related to the their malfunction.

Three research groups and a common commitment -understanding the role of TRP channels in heat sensitivity, pain and synaptic plasticity-  define the project led by Dr. Rodolfo Madrid researcher at the Faculty of Chemistry and Biology. His initiative has recently received funds from the "2011 Fourth Contest of Research Rings in Science and Technology" organized by the National Commission for Scientific and Technological Research, CONICYT. (See related article).

"Study of the Physiological role of TRP Channels in Thermotransduction and Synaptic Plasticity" is an associative research project that joins three research groups: two correspond to the University’s laboratory of neurosciences at the Faculty of Chemistry and Biology -one led by Dr. Rodolfo Madrid and the other by Dr. Bernardo Morales-  the third is the Interdisciplinary Center for Neuroscience from Valparaiso, led by Dr. Patricio Orio. The joint challenge is to study the physiological role of various members of a group of membrane proteins: polymodal ion channels of the TRP (Transient Receptor Potential) superfamily in diverse physiological processes. For this purpose, they will have the annual funds of 150 million pesos, for three years.

"We want to study the role of various TRP channels in the electrical response of thermoreceptors of cold and nociceptors against various physiological and pathophysiological situations, in order to develop a mathematical model that could serve as a tool for predicting the electrical behavior of these neurons against modifications -that could be the result, for example, of an inflammatory process or an injury-  and  determining  the role of ion channels in regulating neuronal communication in particular regions of the central nervous system," Dr. Rodolfo Madrid explains.

"TRP channels are part of a large group of proteins involved in the detection of thermal stimuli and nociception, among many other physiological processes, and have recently been associated with learning and memory processes," the specialist says.
 

Advanced human capital

This associative research, will attract and train new high-level human capital. It will also  incorporate doctoral and postdoctoral students and, in this way, the group of neuroscientists at the University’s Faculty of Chemistry and Biology will become stronger.

"Besides, we will work with the collaboration of laboratories that belong to some of the world's best centers in the field, such as the Institute of Neuroscience in Alicante, Cambridge University and John Hopkins University, worldwide reference points in the study of neuroscience. This will not only help the growth and consolidation of  our group, but it will also allow our students go directly to stay in those centers,” the researcher says.

Besides, Dr. Madrid values ​​the grant of this ring project "as a recognition that should extend not only to the members of our group, but to all the neuroscientists at the University. From our point of view, this is the most important project of neuroscience that our institution has received and it means that our work has not been the result of improvisation, " he finally  points out.
