Overview

Neuropsychiatric diseases are highly heterogeneous and complex disorders, resulting from the interplay between environmental factors and multiple risk factors. In most cases, many genes contribute to the disease pathophysiology due to functional variants undermining key brain-related molecular pathways and circuits. Large scale genomic approaches are showing their potential to identify the key genetic determinants of neuropsychiatric disorders and highlight putative functional mechanisms underlying disease susceptibility. By combining genomic and proteomic approaches in diseased tissues, it is possible to search for biomarker fingerprints that may help disentangling the biological complexity of brain diseases and identifying patient subgroups that are homogeneous in terms of prognosis and drug response.

Research directions

Genetic biomarkers: one of our main interests is the understanding of the contribution of common and rare variants to the risk of neuropsychiatric disorders as well as to intermediate phenotypes. Large scale collaborative efforts such as the Psychiatry Genomics Consortium (PGC) are helping unraveling the complexity of disorders such as schizophrenia, with more than hundred loci contributing to disease susceptibility. Thanks to consortium membership, and in collaboration with PCG members, we are investigating the association between risk variants and molecular or clinical phenotypes.

Functional genomics: we are investigating the genetic control of gene expression in the brain as a way to elucidate the genetic basis of CNS disorders at molecular level. By intersecting transcriptomics and data derived from large scale genetic association studies, it is possible to identify causal candidates among the regulatory variants that modulate gene expression (eQTLs). We are collaborating with the CommonMind Consortium (www.commonmind.org), a public-private effort aimed at generating and analyzing large-scale genomic data from human subjects with neuropsychiatric disorders.

Linking Peripheral and Central Biomarkers: given the evidence of cross-talk between the brain and peripheral systems, we are engaged in the search for non-invasive biomarkers that may help reducing the phenotypic complexity of neuropsychiatric disorders such as depression, schizophrenia and autism, and help stratifying patients into more biologically homogeneous subtypes. In this context, proteomic and genomic tools are expanding by orders of magnitude the number of testable hypothesis and allowing for the identification of molecular signatures rather than single markers. In order to establish correlations between peripheral and central markers, as well as between preclinical and clinical biomarkers, we are pursuing research efforts both in disease collections and in translational models of disease.
