Summary Dysregulation of capillary permeability is a severe problem in critically ill patients, but the mechanisms involved are poorly understood. Further, there are no targeted therapies to stabilize leaky vessels in various common, potentially fatal diseases, such as systemic inflammation and sepsis, which affect millions of people annually. Although a multitude of signals that stimulate opening of endothelial cell-cell junctions leading to permeability have been characterized using cellular and in vivo models, approaches to reverse the harmful process of capillary leakage in disease conditions are yet to be identified. I propose to explore a novel autocrine endothelial permeability regulatory system as a potentially universal mechanism that antagonizes vascular stabilizing ques and sustains vascular leakage in inflammation. My group has identified inflammation-induced mechanisms that switch vascular stabilizing factors into molecules that destabilize vascular barriers, and identified tools to prevent the barrier disruption. Building on these discoveries, my group will use mouse genetics, structural biology and innovative, systematic antibody development coupled with gene editing and gene silencing technology, in order to elucidate mechanisms of vascular barrier breakdown and repair in systemic inflammation. The expected outcomes include insights into endothelial cell signaling and permeability regulation, and preclinical proof-of-concept antibodies to control endothelial activation and vascular leakage in systemic inflammation and sepsis models. Ultimately, the new knowledge and preclinical tools developed in this project may facilitate future development of targeted approaches against vascular leakage.

Call Details Consolidator Grant (CoG), PE1, ERC-2015-CoG
Summary The aim of AROMA-CFD is to create a team of scientists at SISSA for the development of Advanced Reduced Order Modelling techniques with a focus in Computational Fluid Dynamics (CFD), in order to face and overcome many current limitations of the state of the art and improve the capabilities of reduced order methodologies for more demanding applications in industrial, medical and applied sciences contexts. AROMA-CFD deals with strong methodological developments in numerical analysis, with a special emphasis on mathematical modelling and extensive exploitation of computational science and engineering. Several tasks have been identified to tackle important problems and open questions in reduced order modelling: study of bifurcations and instabilities in flows, increasing Reynolds number and guaranteeing stability, moving towards turbulent flows, considering complex geometrical parametrizations of shapes as computational domains into extended networks. A reduced computational and geometrical framework will be developed for nonlinear inverse problems, focusing on optimal flow control, shape optimization and uncertainty quantification. Further, all the advanced developments in reduced order modelling for CFD will be delivered for applications in multiphysics, such as fluid-structure interaction problems and general coupled phenomena involving inviscid, viscous and thermal flows, solids and porous media. The advanced developed framework within AROMA-CFD will provide attractive capabilities for several industrial and medical applications (e.g. aeronautical, mechanical, naval, off-shore, wind, sport, biomedical engineering, and cardiovascular surgery as well), combining high performance computing (in dedicated supercomputing centers) and advanced reduced order modelling (in common devices) to guarantee real time computing and visualization. A new open source software library for AROMA-CFD will be created: ITHACA, In real Time Highly Advanced Computational Applications.

Summary Recent advances in systems-level study of cells and organisms have revealed the enormous potential to live more sustainably through better use of biological processes. Plants sustainably synthesize the most abundant and diverse materials on Earth. By applying recent advances in life science technology, we can better harness renewable plant resources and bioconversion processes, to develop environmentally and politically sustainable human enterprise and lifestyles. At the same time, the global market for high-value biochemicals and bioplastics from forest and agricultural sources is rapidly increasing, which presents new opportunities for forest and agricultural sectors.
The overall aim of BHIVE is to illuminate uncharted regions of genome and metagenome sequences to discover entirely new protein families that can be used to sustainably synthesize novel, high-value biomaterials from renewable plant resources. The approach will include three parallel research thrusts: 1) strategic analysis of transcriptome and metagenome sequences to identify proteins with entirely unknown function relevant to biomass (lignocellulose) transformation, 2) mapping of uncharted regions within phylogenetic trees of poorly characterized enzyme families with recognized potential to modify the chemistry and biophysical properties of plant polysaccharides, and 3) the design and development of novel enzyme screens to directly address the increasing limitations of existing assays to uncover entirely new protein functions. BHIVE will be unique in its undivided focus on characterizing lignocellulose-active proteins encoded by the 30-40% of un-annotated sequence, or genomic “dark matter”, typical of nearly all genome sequences. In this way, BHIVE tackles a key constraint to fully realizing the societal and environmental benefits of the genomics era.

Summary Heterogeneous biomolecular mechanisms at the surface of cellular membranes are often fundamental to generate function and dysfunction in living systems. These processes are governed by transient and dynamical macromolecular interactions that pose tremendous challenges to current analytical tools, as the majority of these methods perform best in the study of well-defined and poorly dynamical systems. This proposal aims at a radical innovation in the characterisation of complex processes that are dominated by structural order and disorder, including those occurring at the surface of biological membranes such as cellular signalling, the assembly of molecular machinery, or the regulation vesicular trafficking.
I outline a programme to realise a vision where the combination of experiments and theory can delineate a new analytical platform to study complex biochemical mechanisms at a multiscale level, and to elucidate their role in physiological and pathological contexts. To achieve this ambitious goal, my research team will develop tools based on the combination of nuclear magnetic resonance (NMR) spectroscopy and molecular simulations, which will enable probing the structure, dynamics, thermodynamics and kinetics of complex protein-protein and protein-membrane interactions occurring at the surface of cellular membranes. The ability to advance both the experimental and theoretical sides, and their combination, is fundamental to define the next generation of methods to achieve our transformative aims. We will provide evidence of the innovative nature of the proposed multiscale approach by addressing some of the great questions in neuroscience and elucidate the details of how functional and aberrant biological complexity is achieved via the fine tuning between structural order and disorder at the neuronal synapse.

Summary In BIORECAR I will develop a new breakthrough multifunctional biomaterial-based platform for myocardial regeneration after myocardial infarction, provided with biochemical cues able to enhance the direct reprogramming of human cardiac fibroblasts into functional cardiomyocytes.
My expertise in bioartificial materials and biomimetic scaffolds and the versatile chemistry of polyurethanes will be the key elements to achieve a significant knowledge and technological advancement in cell reprogramming therapy, opening the way to the future translation of the therapy into the clinics.
I will implement this advanced approach through the design of a novel 3D in vitro tissue-engineered model of human cardiac fibrotic tissue, as a tool for testing and validation, to maximise research efforts and reduce animal tests.
I will adapt novel nanomedicine approaches I have recently developed for drug release to design innovative cell-friendly and efficient polyurethane nanoparticles for targeted reprogramming of cardiac fibroblasts.
I will design an injectable bioartificial hydrogel based on a blend of a thermosensitive polyurethane and a natural component selected among a novel cell-secreted natural polymer mixture (“biomatrix”) recapitulating the complexity of cardiac extracellular matrix or one of its main protein constituents. Such multifunctional hydrogel will deliver in situ agents stimulating recruitment of cardiac fibroblasts together with the nanoparticles loaded with reprogramming therapeutics, and will provide biochemical signalling to stimulate efficient conversion of fibroblasts into mature cardiomyocytes.
First-in-field biomaterials-based innovations introduced by BIORECAR will enable more effective regeneration of functional myocardial tissue respect to state-of-the art approaches. BIORECAR innovation is multidisciplinary in nature and will be accelerated towards future clinical translation through my clinical, scientific and industrial collaborations.

Summary We aim to understand host cell entry of enveloped viruses at molecular level. A crucial step in this process is when the viral membrane fuses with the cell membrane. Similarly to cell–cell fusion, this step is mediated by fusion proteins (classes I–III). Several medically important viruses, notably dengue and many bunyaviruses, harbour a class II fusion protein. Class II fusion protein structures have been solved in pre- and post-fusion conformation and in some cases different factors promoting fusion have been determined. However, questions about the most important steps of this key process remain unanswered. I will focus on the entry mechanism of bunyaviruses by using cutting-edge, high spatial and temporal resolution bio-imaging techniques. These viruses have been chosen as a model system to maximise the significance of the project: they form an emerging viral threat to humans and animals, no approved vaccines or antivirals exist for human use and they are less studied than other class II fusion protein systems. Cryo-electron microscopy and tomography will be used to solve high-resolution structures (up to ~3 Å) of viruses, in addition to virus–receptor and virus–membrane complexes. Advanced fluorescence microscopy techniques will be used to probe the dynamics of virus entry and fusion in vivo and in vitro. Deciphering key steps in virus entry is expected to contribute to rational vaccine and drug design. During this project I aim to establish a world-class laboratory in structural and cellular biology of emerging viruses. The project greatly benefits from our unique biosafety level 3 laboratory offering advanced bio-imaging techniques. Furthermore it will also pave way for similar projects on other infectious viruses. Finally the novel computational image processing methods developed in this project will be broadly applicable for the analysis of flexible biological structures, which often pose the most challenging yet interesting questions in structural biology.

Summary One out of 5 people in their fifties will experience a bone fracture due to osteoporosis (OP)-induced fragility in their lifetime. The OP socio-economic burden is dramatic and involves tens of millions of people in the EU, with a steadily increasing number due to population ageing. Current treatments entail drug-therapy coupled with a healthy lifestyle but OP fractures need mechanical fixation to rapidly achieve union: the contribution of biomaterial scientists in this field is still far from taking its expected leading role in cutting-edge research. Bone remodelling is a well-coordinated process of bone resorption by osteoclasts followed by the production of new bone by osteoblasts. This process occurs continuously throughout life in a coupling with a positive balance during growth and negative with ageing, which can result in OP. We believe that an architecture driven stimulation of the osteoclast/osteoblast coupling, with an avant-garde focus on osteoclasts activity, is the key to success in treating unbalanced bone remodelling. We aim to manufacture a scaffold that mimics healthy bone features which will establish a new microenvironment favoring a properly stimulated and active population of osteoclasts and osteoblasts, i.e. a well-balanced bone cooperation. After 5 years we will be able to prove the efficacy of this approach. A benchmark will be set up for OP fracture treatment and for the realization of smart bone substitutes that will be able to locally “trick” aged bone cells stimulating them to act as healthy ones. BOOST results will have an unprecedented impact on the scientific research community, opening a new approach to set up smart, biomimetic strategies to treat aged, unbalanced bone tissues and to reduce OP-associated disabilities and financial burdens.

Summary The possibility of having a unique device that converts thermal and photonics energy into electrical energy and simultaneously stores it, is something dreamed by the PI since the beginning of her research career. To achieve that goal, this project aims to gather, in a single substrate, solar cells with up-conversion nanoparticles, thermoelectrics and graphene super-capacitor, all made of thin films. These three main components will be developed separately and integrated sequentially. The innovation proposed is not limited to the integration of components, but rely in ground-breaking concepts: 1) thermoelectric elements based on thin film (TE-TF) oxides; 2) plasmonic nanoparticles for up conversion of near infrared radiation to visible emission in solar cells; 3) graphene super-capacitors; 4) integration and optimization of all components in a single CapTherPV device. This ambitious project will bring new insights at large area, low cost and flexible energy harvesting and comes from an old idea of combining energy conversion and storage that has been pursued by the PI. She started her career in amorphous silicon thin film solar cells, later she started the development of thin film batteries and more recently started a research line in thermoelectric films. If approved, this project will give financial support to consolidate the research being carried out and will give independence to the PI in terms of resources and creative think. More importantly, will facilitate the concretization of the dream that has been pursued with hard work.

Summary Which physical principles govern life regulation at the level of subcellular, membrane-enclosed nanosystems, such as transport vesicles and organelles? How do they achieve controlled movements across the crowded intracellular world? Which is the structural and functional organization of their surface and their lumen? This is only a small subset of key open questions that the biophysical approach envisaged here will allow to answer directly within living matter, for the first time.
Thus far, state-of-the-art optical microscopy tools for delivering quantitative information in living matter failed to subtract the natural 3D movement of subcellular nanosystems while preserving the spatial and temporal resolution required to probe their structure and function at the molecular level.
CAPTUR3D will tackle this bottleneck. An excitation light-beam will be focused in a periodic orbit around the nanosystem of interest and used to localize its position with unprecedented spatial (~10 nm) and temporal (~1000 Hz frequency response) resolution. Such privileged observation point will push biophysical investigations to a new level. For the first time, state-of-the-art imaging technologies and analytical tools (e.g. fluorescence correlation spectroscopy), will be used to perform molecular investigations on a moving, nanoscopic reference system.
The insulin secretory granule (ISG) is selected as a paradigmatic case study. Key open issues at the ISG level are selected, namely: (i) ISG-environment interactions and their role in directing ISG trafficking, (ii) ISG-membrane spatiotemporal organization, (iii) ISG-lumen structural and functional organization, (iv) ISG alterations in type-2 diabetes (T2D). These issues will be tackled directly within human-derived Langherans islets.
CAPTUR3D is envisioned not only to foster our knowledge on T2D physiopathology but also to concomitantly drive an unprecedented revolution in the way we address living matter at the subcellular scale.

Summary Spacetime defines existence and evolution of materials. A key path to human’s sustainability through materials innovation can hardly circumvent materials dimensionalities. Despite numerous studies in electrically distinct 2D semiconductors, the route to engage them in high-performance photocatalysts remains elusive. Herein, CATCH proposes a cross-dimensional activation strategy of 2D semiconductors to implement practical photocatalysis. It operates electronic structures of dimensionally paradoxical 2D semiconductors and spatially limited nD (n=0-2) guests, directs charge migration processes, mass-produces advanced catalysts and elucidates time-evolved catalysis. Synergic impacts crossing 2D-nD will lead to > 95%/hour rates for pollutant removal and >20% quantum efficiencies for H2 evolution under visible light. CATCH enumerates chemical coordination and writes reaction equations with sub-nanosecond precision.
CATCH employs density functional theory optimization and data mining prediction to select most probable heterojunctional peers from hetero/homo- dimensions. Through facile but efficient wet and dry synthesis, nanostructures will be bonded to basal planes or brinks of 2D slabs. CATCH benefits in-house techniques for product characterizations and refinements and emphasizes on cutting-edge in situ studies to unveil photocatalysis at advanced photon sources. Assisted with theoretical modelling, ambient and time-evolved experiments will illustrate photocatalytic dynamics and kinetics in mixed spacetime.
CATCH unites low-dimensional materials designs by counting physical and electronic merits from spacetime confinements. It metrologically elaborates photocatalysis in an elevated 2D+nD+t, alters passages of materials combinations crossing dimensions, and directs future photocatalyst designs. Standing on cross-dimensional materials innovation and photocatalysis study, CATCH breaks the deadlock of practical photocatalysis that eventually leads to sustainability.

It metrologically elaborates photocatalysis in an elevated 2D+nD+t, alters passages of materials combinations crossing dimensions, and directs future photocatalyst designs. Standing on cross-dimensional materials innovation and photocatalysis study, CATCH breaks the deadlock of practical photocatalysis that eventually leads to sustainability.
