Summary The objective of Manifestations of Solitude: Withdrawal and Engagement in the long seventeenth-century is to demonstrate how the creation of zones of unworldliness within the world structures re-ligious practice. We will examine withdrawal in its historical settings and uncover the facetted na-ture of this phenomenon in the seventeenth-century religious culture, thus offering insights and tools for a better understanding of the representation of religious experience in European culture.
Working across cultural and confessional boundaries, the project explores appropriations of the appeal that the Christian be in the world but not of the world: in texts, architecture, images and mu-sic, and it examines the ways in which these media are employed to prompt and sustain with¬drawal from the world. The project focuses on ten institutional social units (e.g. the abbey, the Konventikel, the household), which manifest solitude in different ways. It examines such units through ten exem-plary places (e.g. Herrnhut, Saint-Cyr) and their cultural and reli¬gious life, drawing on materials such as architectural plans, interior decoration, treatises on theology and aesthetics, letters, diaries, epitaphs, emblems, portraits, devotional images, sermons and musical pieces.
The backbone of the project is an innovative strategy for interdisciplinary analysis which traces the generation of a symbolically charged space around religious withdrawals. With this analytical tool we will examine how symbols of ‘world’, ‘solitude’ and the demarcation between them are materialized in forms ranging from material culture (architecture, furnishing), via artistic, perfor-mative expressions (devotional images, musical pieces) to literary topoi and metaphors and the in-fluence on such forms of contemporary aesthetic sensibilities. The project examines the cultivation of the religious self: shaping a sym¬bolically charged space – and shaped in turn by this space.

Project Synaptic Tagging and Capture: From Synapses to Behavior

Summary It is shown that long-term potentiation (LTP) is the cellular basis of memory formation. However, since all but small fraction of memories are forgotten, LTP has been further divided into early LTP (e-LTP), the mechanism by which short-term memories are formed, and a more stable late LTP (L-LTP), by which long-term memories are formed. Remarkably, it has been shown that an e-LTP can be stabilized if it is preceded or followed by heterosynaptic L-LTP.
According to Synaptic Tagging and Capture (STC) hypothesis, e-LTP is stabilized by capturing proteins that are made by L-LTP induction. The model proposes that this mechanism underlies the formation of late associative memory, where the stability of a memory is not only defined by the stimuli that induce the change but also by events happening before and after these stimuli. As such, the model explicitly predicts that a short-term memory can be stabilized by inducing heterosynaptic L-LTP.
In this grant, I will put this hypothesis into test. Specifically, I will test two explicit predictions of STC model: 1) A naturally formed short-term memory can be stabilized by induction of heterosynaptic L-LTP. 2) This stabilization is caused by the protein synthesis feature of L-LTP. To do this, using optogenetics, I will engineer a short-term memory in auditory fear circuit, in which an animal transiently associates a foot shock to a tone. Subsequently, I will examine if optogenetic delivery of L-LTP to the visual inputs converging on the same population of neurons in the amygdala will stabilize the short-term tone fear memory.
To be able to engineer natural memory by manipulating synaptic plasticity I will develop two systems: 1) A two-color optical activation system which permits selective manipulation of distinct neuronal populations with precise temporal and spatial resolution; 2) An inducible and activity-dependent expression system by which those neurons that are activated by a natural stimulus will be optically tagged.

Summary Glycans are ubiquitous biomolecules found throughout all kingdoms of life. Early studies contributed considerably to our appreciation of glycan functions by showing that abnormalities in the glycosylation can develop into pathogenesis and severe dysfunctions. Despite the crucial role of sugars in many biological events we still do not have adequate tools to decipher their complexity. To unveil the mysteries in the rapidly emerging field of glycobiology we aim in this proposal to develop new tools that will help us to study and understand these important biomolecules. To realize this, we plan to combine the unique targeting capability of biologics with the inhibitory effect of small molecules into robust constructs with advanced properties. The biological part of the construct will be evolved using synthetic peptide libraries ensuring high selectivity toward particular sugar processing enzymes. The second part of the construct will consist of small molecular inhibitor warhead that will be designed and synthesized based on crystal structure-aided analyses. To merge these two moieties we aim to develop a new target enzyme–templated fluorogenic in situ click chemistry methodology that will enable us to easily monitor and screen whole peptide–small molecule bioconjugate libraries as highly selective inhibitors and manipulators of sugar processing enzymes. In addition, we aim to create new multivalent heteroglycosystems by using bioorthogonal reactions on peptide library scaffold. These structures will enable us to study polyvalent carbohydrate–protein interactions and to generate novel therapeutics such as influenza virus entry blockers. Our goal is to develop a new class of smart bioconjugate probes that will help us to answer fundamental questions in glycobiology. The outcomes of this project will significantly deepen our knowledge of glycoconjugates and in the long term, will allow for the design of efficient vaccines and for the development of selective therapeutics.
