Neurons communicate with each other at synapses, extremely specialized and plastic structures able to adjust both quantitatively and qualitatively to correctly respond to a changing environment. The majority of neuronal communication is mediated by the activation of glutamate receptors (GluRs), which triggers mechanisms able to induce changes at synaptic level that are thought to underlie higher cognitive functions. Accordingly, GluRs are extremely well regulated in a cell- and synapse-specific manner. Several mechanisms including the control of expression/degradation level, intracellular trafficking or channel properties work coordinately to regulate GluRs. Not surprisingly, an aberrant GluR trafficking and/or function is a shared hallmark for many neurological disorders, including Alzheimer’s disease, Huntington’s disease, schizophrenia and autism.

The Sanz-Clemente Lab is interested in the molecular mechanisms underlying GluR trafficking in normal and altered conditions. We use a multidisciplinary approach including biochemistry, cell and molecular biology, pharmacology as well as a variety of imaging techniques and the analysis of genetically-altered mouse lines for elucidating how GluRs are controlled during development, in response to experience or other stimuli and what is their impact on synaptic function. Similarly, we investigate how the dysregulation of these mechanisms leads to synaptic alterations and, eventually, to neurological disorders. Current research focuses on NMDA Receptor (NMDAR) regulation and its role in the pathogenesis of Alzheimer’s disease.

Current projects
• Investigating the molecular mechanisms controlling the balance between synaptic and extrasynaptic NMDARs and its role in the pathogenesis of Alzheimer’s disease
• Investigating the molecular mechanisms underlying synapse unsilencing during development
• Studying the differential reorganization of synaptic protein content by typical and atypical antipsychotic drugs
