Summary The global performing arts community is requiring innovative systems to: a) document, transmit and preserve the knowledge contained in choreographic-dramaturgic practices; b) assist artists with tools to facilitate their compositional processes, preferably on a collaborative basis. The existing digital archives of performing arts mostly function as conventional e-libraries, not allowing higher degrees of interactivity or active user intervention. They rarely contemplate accessible video annotation tools or provide relational querying functionalities based on artist-driven conceptual principles or idiosyncratic ontologies.
This proposal endeavours to fill that gap and create a new paradigm for the documentation of performance composition. It aims at the analysis of artists’ unique conceptual structures, by combining the empirical insights of contemporary creators with research theories from Multimodal Communication and Digital Media studies. The challenge is to design a model for a web-based collaborative platform enabling both a robust representation of performance composition methods and novel visualization technologies to support it. This can be done by analysing recurring body movement patterns and by fostering online contributions of users (a.o. performers and researchers) to the multimodal annotations stored in the platform. To accomplish this goal, two subjacent components must be developed: 1. the production of a video annotation-tool to allow artists in rehearsal periods to take notes over video in real-time and share them via the collaborative platform; 2. the linguistic analysis of a corpus of invited artists’ multimodal materials as source for the extraction of indicative conceptual structures, which will guide the architectural logics and interface design of the collaborative platform software.The outputs of these two components will generate critical case-studies to help understanding the human mind when engaged in cultural production processes.

Summary A great deal is known about the neural basis of associative fear learning. However, many animal species are able to use social cues to recognize threats, a defence mechanism that may be less costly than learning from self-experience. We have previously shown that rats perceive the cessation of movement-evoked sound as a signal of danger and its resumption as a signal of safety. To study transmission of fear between rats we assessed the behavior of an observer while witnessing a demonstrator rat display fear responses. With this paradigm we will take advantage of the accumulated knowledge on learned fear to investigate the neural mechanisms by which the social environment regulates defense behaviors. We will unravel the neural circuits involved in detecting the transition from movement-evoked sound to silence. Moreover, since observer rats previously exposed to shock display observational freezing, but naive observer rats do not, we will determine the mechanism by which prior experience contribute to observational freezing. To this end, we will focus on the amygdala, crucial for fear learning and expression, and its auditory inputs, combining immunohistochemistry, pharmacology and optogenetics. Finally, as the detection of and responses to threat are often inherently social, we will study these behaviors in the context of large groups of individuals. To circumvent the serious limitations in using large populations of rats, we will resort to a different model system. The fruit fly is the ideal model system, as it is both amenable to the search for the neural mechanism of behavior, while at the same time allowing the study of the behavior of large groups of individuals. We will develop behavioral tasks, where conditioned demonstrator flies signal danger to other naïve ones. These experiments unravel how the brain uses defense behaviors as signals of danger and how it contributes to defense mechanisms at the population level.

Summary "The megadalton cytoplasmic dynein complex, whose motor subunit is encoded by a single gene, provides the major microtubule minus end-directed motility in cells and is essential for a wide range of processes, ranging from the transport of proteins, RNA, and membrane vesicles to nuclear migration and cell division. To achieve this stunning functional diversity, cytoplasmic dynein is subject to tight regulation by co-factors that modulate localization, interaction with cargo, and motor activity. At present, our knowledge of the underlying mechanisms remains limited. An overarching goal of this proposal is to gain an understanding of how interactions with diverse adaptor proteins regulate dynein function in space and time. We choose the nematode C. elegans as our model system, because it will enable us to study the biology of dynein regulation in the broad context of a metazoan organism. The nematode’s versatile genetic tools, its biochemical tractability, and the powerful molecular replacement technologies available, this makes for a uniquely attractive experimental system to address the mechanisms employed by dynein regulators through a combination of biochemical, proteomic, and cell biological assays. Specifically, we propose to use a biochemical reconstitution approach to obtain a detailed molecular picture of how dynein is targeted to the mitotic kinetochore; we will perform a forward genetic and proteomic screen to expand the so-far limited inventory of metazoan dynein interactors, whose functional characterization will shed light on known dynein-dependent processes and lead to novel unanticipated lines of research into dynein regulation; we will dissect the function and regulation of the most important dynein co-factor, the multi-subunit dynactin complex; and finally we will strive to establish a novel C. elegans model for human neurodegenerative disease, based on pathogenic point mutations in a dynactin subunit."

Project acronym PICOSTRUCTURE
Project Structural studies of human picornaviruses

Host Institution (HI) Masarykova univerzita
Call Details Starting Grant (StG), LS1, ERC-2013-StG
Summary Many picornaviruses are human pathogens that cause diseases varying in symptoms from common cold to life-threatening encephalitis. Currently there are no anti-picornavirus drugs approved for human use. We propose to study molecular structures of picornaviruses and their life cycle intermediates in order to identify new targets for anti-viral inhibitors and to lay the foundations for structure-based development of drugs against previously structurally uncharacterized picornaviruses.
We will use X-ray crystallography to determine virion structures of representative viruses from Parechovirus, Kobuvirus, Cardiovirus, and Cosavirus genera and Human Rhinovirus-C species. We will use cryo-electron microscopy to study picornavirus replication complexes in order to explain the mechanism of copy-choice recombination of picornavirus RNA genomes that leads to creation of new picornavirus species. We will determine whether picornavirus virions assemble from capsid protein protomers around the condensed genome or if the genome is packaged into a pre-formed empty capsid. Furthermore, we will investigate how picornaviruses initiate infection by analyzing genome release from virions and its translocation across lipid membrane.
A major innovation in our approach will be the use of focused ion beam micromachining for sample preparation that will allow us to study macromolecular complexes within infected mammalian cells by cryo-electron tomography. Our analysis of virion structure, cell entry, genome replication, and particle assembly will identify molecular details and mechanism of function of critical picornavirus life-cycle intermediates.
