About

Lorenzo Cingolani graduated in Molecular Biology at the University of Pisa. For his PhD, he joined the department of Prof. Walter Stuehmer at the Max-Planck Institute for Experimental Medicine, Goettingen, where he investigated the developmental regulation of calcium-activated potassium channels in the rodent brain. For these studies, he received a Ph.D. in Neurobiology from the Humboldt University of Berlin in 2002. As postdoctoral fellow, he joined the laboratory of Dr. Yukiko Goda  at the MRC Laboratory for Molecular Cell Biology (University College London), where he studied the relationship between synaptic structure and function, uncovering the role of cell adhesion molecules in homeostatic synaptic plasticity. Since 2012, he is an independent investigator at the Italian Institute of Technology (IIT).

Molecular mechanisms of synapse specificity and function in the central nervous system

 

Our goal is to identify the key molecular mechanisms controlling assembly and remodeling of synaptic connections in the mammalian brain. Knowledge of the general principles governing development and function of neuronal connections is fundamental for the understanding of neurological and psychiatric disorders.

 

Quite possibly the most complex organ in our body, the brain determines how we behave and think, and who we are. Activity-dependent changes in the structure and function of the brain make it possible to form new memories and learn new skills. Alterations in its connectivity and excitability can lead to diseases such as epilepsy and autism, which are amongst the most common and disabling mental disorders.

 

Brain function: focus on cell adhesion molecules and calcium channels

FigWebSiteTextRedBrain function critically depends on how neurons interact and communicate with each others at specialized contact sites, the synapses. Our aim is to identify the key molecular mechanisms governing formation, specialization and remodeling of synaptic connections in the central nervous system. Synapses can be viewed as learning and memory storage devices. They are highly ‘plastic’, changing the way they transmit information between neurons in response to specific patterns of neuronal activity. At the same time, they are also highly ‘tenacious’, with many synapses retaining their structural and functional properties over many years. Our overarching interest is in the questions of how synapses find the right balance between plasticity and stability, and how alterations in this delicate equilibrium contribute to neurological disorders.

We address these questions at a cellular and molecular level.

First, we investigate how a class of synaptic cell adhesion molecules (CAMs), the integrins, contribute to synaptic specificity and to coordinating pre- and postsynaptic activity under physiological and pathological conditions. During synapse formation, CAMs are critically involved in determining synapse specificity by mediating the initial target recognition between pre- and post-synaptic neurons. In mature synapses, they regulate structural and functional synaptic plasticity by signaling between the two sides of the synapse.

Second, we study how alternative splicing of pre-mRNAs makes it possible to produce different versions of synaptic proteins to suit diverse types of synapses. Alternative splicing is a process during the maturation of mRNAs that enables a single gene to produce multiple variants of a protein; it is especially prominent in the mammalian brain, where it is thought to expand proteome diversity. For example, alternative splicing of calcium channels can potentially generate thousands of different versions of these synaptic proteins. However, the impact of this molecular diversity on brain function, especially on synaptic transmission, starts only now to be uncovered.

 

Current projects

Synaptic functions of integrin-mediated cell adhesion in physiological conditions and autism-related abnormalities in mice, project supported by the European Research Council (SynAMPAdhesion, FP7-PEOPLE-2012-CIG) and the Italian Institute of Technology.

Autism has a complex genetic architecture, with up to hundreds of genes involved in its etiology. A major question in the neurobiology of autism is how alterations in these many genes translate into similar behavioral phenotypes. The goal of this project is to provide mechanistic insights on how the interplay between cell adhesion molecules (integrins) and glutamate receptors alters key neuronal circuits in autism. To this end, we employ bioinformatics, brain slice electrophysiology coupled with optogenetics and behavioral analysis in mice.

 

Elucidation of causality between αV integrin deficiency and epilepsy, project part of the European Training Network on Extracellular Matrix in Epileptogenesis (ECMED, H2020-MSCA-ITN-2014).

Extracellular matrix proteins and their receptors are readily accessible to pharmacological and molecular interventions, and they play a fundamental role in neural development and network excitability, crucial events in the pathogenesis of epilepsy. This project aims to understanding the molecular mechanisms of epileptogenesis mediated by activity-dependent remodeling of extracellular matrix receptors, and to develop treatments for 'opening a window' of persistent structural normalization of neural circuitries in epileptogenesis, as well as in established epilepsy. To this end, we employ electrophysiological recordings from brain slices and primary neuronal cultures, Ca2+ imaging and viral-mediated rescue strategies.

 

Activity-dependent alternative splicing of presynaptic calcium channels, project supported by the Italian Institute of Technology

The majority of neuronal genes are subject to alternative splicing, which is thought to increase proteome complexity and optimize protein function to specific cellular tasks. In support of a dedicated function of individual splice variants, some mutations that cause brain diseases impair only one of the splice isoforms of a neuronal gene. By combining optogenetic stimulation with isoform-specific knock-down, along with imaging of presynaptic calcium and vesicle turnover, we have recently demonstrated that alternative splicing of P/Q-type calcium channels is regulated in an activity-dependent manner to control vesicle release and presynaptic plasticity at hippocampal synapses.  Paper here.

 

Genome-editing approaches for personalized medicine in inherited diseases, project supported by the Compagnia San Paolo and the Italian Institute of Technology.

This project aims to developing novel strategies for personalized medicine in inherited brain diseases with a complex and multifactorial genetic architecture. To this end, we employ CRISPR/Cas9-based genome-editing technology to correct the genetic defects at the base of inherited forms of autism.
