Research Interest

Cellular and molecular mechanisms of neuron-oligodendrocyte communication. Brain functions are the result of multiple intercellular communication processes. Myelination of axons is one of the fundamental phenomena that allow communication in the nervous system. Through myelination, the axons of the central nervous system are wrapped by myelin-producing oligodendrocytes. This envelope protects and promotes the survival of neurons. Its structure also allows the generation of specialized membrane domains, which modify the biophysical characteristics of the axon, in such a way that it allows the rapid propagation of the nervous impulse. Failure in the formation of myelin has serious consequences on brain functions, this is what happens in several pathologies that together are called demyelinating diseases. Recently, in addition, the role of myelination in different cognitive processes has begun to be recognized, as well as in the etiology of various mental disorders. Due to its importance, it is necessary to increase basic knowledge to achieve its control, and to be able to promote myelination in cases of interest. In the Cellular Neurophysiology laboratory of the Institute of Neurobiology, we study aspects of the dialogue that neurons establish with oligodendrocytes, and we are interested in knowing the signaling systems that initiate, promote, and maintain their intercommunication. For this, we use the most advanced techniques and concepts of electrophysiology, molecular and cellular biology, and morphological sciences. We think that the moment when an oligodendrocyte establishes contact with the axon, and the myelination program is turned on, is a critical event in the establishment of their relationship. Due to this, we have focused on the study of its properties in this particular time window, promoting its encounter under controlled experimental conditions (both in vitro and in situ). Knowledge about the communication processes that occur during this vital encounter will be useful in understanding and controlling the subsequent phenomenon of myelination. We believe that it will provide useful information in the design of new treatments against demyelinating diseases, and will expand our understanding of its role in brain functions.
