 EN COURS 
During S-phase newly synthesized “sister” DNA molecules become physically connected. This sister chromatid cohesion resists the pulling forces of the mitotic spindle and thereby enables the bi-orientation and subsequent symmetrical segregation of chromosomes. Cohesion is mediated by ring-shaped cohesin complexes, which are thought to entrap sister DNA molecules topologically. In mammalian cells, c ...

Cellular proteins are prone to misfolding and aggregation, particularly under harsh environmental conditions. To counteract this danger, all organisms from bacteria to humans evolved sophisticated protein quality control networks. The mechanisms employed in them tend to represent some of the most exciting biochemistry occurring in living cells.In Gram-positive bacteria, the key factors combating p ...

A major goal in biology is to understand how gene regulatory information is encoded by the human genome and how it defines different gene expression programs and cell types. Enhancers are genomic elements that control transcription, yet despite their importance, only a minority of enhancers are known and functionally characterized. In particular, their activity changes during cellular signalling o ...

Elucidating the molecular mechanism of cohesin-loading (Cohesin loading)

Date du début: 1 avr. 2017, Date de fin: 31 mars 2019,

The cohesin-complex mediates sister chromatid cohesion from S-phase until mitosis and is involved in the formation of higher-order chromatin structure. To fulfill these vital functions, cohesin is loaded and positioned in the genome by mechanisms that are only poorly understood. In vitro, loading of cohesin on DNA only requires ATP and a loading-complex formed by Scc2-Scc4, while loading in vivo o ...

The Cellular and Molecular Basis of Magnetoreception (CeMoMagneto)

Date du début: 1 avr. 2014, Date de fin: 31 mars 2019,

Each year millions of animals undertake remarkable migratory journeys, across oceans and through hemispheres, guided by the Earth’s magnetic field. The cellular and molecular basis of this enigmatic sense, known as magnetoreception, remains an unsolved scientific mystery. One hypothesis that attempts to explain the basis of this sensory faculty is known as the magnetite theory of magnetoreception. ...

Spatio-temporal specificity of miRNA function (mirspecificity)

Date du début: 1 févr. 2014, Date de fin: 31 janv. 2019,

MicroRNAs are versatile regulators of gene expression and as such, they are essential parts of the gene regulatory networks controlling development and physiology of animals and plants. In particular, a number of miRNAs have been implicated in cell-type differentiation. Adding miRNAs to existing networks in particular subsets of cells can increase the complexity of developmental programs, and thus ...

The dynamic of neural computation is often studied in individual cells using inserted electrodes, or using low-resolution methods such as EEG. Functional fluorescent imaging has recently emerged as a powerful complementary tool that allows single-cell resolution of relatively large networks, opening a new regime to neuroscience. However, complex brains are generally opaque and can only be studied ...

Circuit mechanics of emotions in the limbic system (EmotionCircuits)

Date du début: 1 janv. 2013, Date de fin: 31 déc. 2017,

Numerous studies established the role of the limbic system in fear and reward: it integrates sensory information, encodes emotional states and instructs other brain centers to regulate physiology and behavior. The limbic system, however, consists of many distinct and highly interconnected neuronal populations. Resolving how emotions are processed in this network at the level of single neural circu ...

Linking neural circuits to visual guidance in flying flies (FLYVISUALCIRCUITS)

Date du début: 1 janv. 2012, Date de fin: 31 déc. 2017,

The brain of a fly is capable of steering the animal through a complex environment at high relative speeds, avoiding stationary obstacles and moving predators. Because it is relatively easy to study how flies do this at several levels, from the behavioral to the cellular, fly vision has long been recognized as an ideal system to address a fundamental question in neuroscience- how does the distribu ...

An animal’s decision on how to respond to the environment is based not only on the sensory information available, but further depends on internal factors such as stress, sleep / wakefulness, hunger / satiety and experience. Neurotransmitters and neuropeptides in the brain modulate neural circuits accordingly so that appropriate behaviors are generated. Aberrant neuromodulation is implicated in dis ...

Emotions are a central part of our mental self and health, playing a crucial role in guiding behaviors essential for survival. For instance, threats evoke fear and avoidance behaviors; conversely, rewards induce reward-states and approach behaviors. Resolving how the variety of emotions emerges in the brain remains a major challenge for modern neuroscience. The main objective of the proposed resea ...

Neural basis of Drosophila mating behaviours (Fru circuit)

Date du début: 1 juil. 2009, Date de fin: 30 sept. 2013,

How does information processing in neural circuits generate behaviour? Answering this question requires identifying each of the distinct neuronal types that contributes to a behaviour, defining their anatomy and connectivity, and establishing causal relationships between their activity, the activity of other neurons in the circuit, and the behaviour. Here, I propose such an analysis of the neural ...
