Research summary:

Our group, "Molecular mechanisms of Neurodegeneration and Regeneration ", is a line established in the CBM over several years. We are interested in the analysis of the molecular mechanisms fired by processes neurodegenerative, trying to understand the key points of these processes; for a second attempt to design new regenerative alternatives, or to propose new therapeutic targets.

First, our studies of molecular mechanisms of degeneration are focused on the role of Pi3K-Akt: GSK3 in neurodegeneration We have seen that some neuroprotective elements as estradiol modulates elements, such as GSK3 and β-catenin, proteins shared by other signaling pathways like Wnt. And we recently demonstrate that estradiol may trigger Akt-mTORC1 pathway. All these data represent a new signalling pathway, triggered by estradiol that would complement to IGF-1 and Wnt. These findings have led us to extend the analysis of signalling mediated by Estradiol in normal neuronal physiology and in some pathological conditions such as Ischemia model.

Second and complementary we are interested in the molecular mechanisms that regulate the generation and maintenance of the axonal polarity. This morphological polarity appears during development when the neuron differentiates and begins to extend an axon. Subsequently they "mature" and form their initial segment of the axon. Studies of several laboratories, including ours have shown that PI3K-kinase activity allows axonal growth and determining axonal polarity (in collaboration with JJ. Garrido´s group from Cajal Inst.). Our laboratory has helped identify some of the elements that control polarity, such that GSK3, control the polarity. Our work, in this field, will follow to identify upstream and downstream elements that would be essential for this "morphogenetic process".

In summary, we are focusing on track PI3K-Akt signalling and elements than those elements that control neuron morphogenesis and are modified in pathology.
