Different topics, focusing on the extracellular matrix, will be discussed: Each session will be completed by short oral communications and poster presentations. Through the topics addressed during this congress, the SFBMEc wants to enrich the interactions between basic research, the medical world and the industrial world.
Below is a taste of the sorts of project that students might become involved with:. There are also opportunities to patent, publish and commercialise significant new findings. We are able to struvturale fellowships and subsidised university accommodation for outstanding students, and normal tuition fees and living costs are still very reasonable for those who are not eligible for assistance. Taiwan is a modern, convenient and safe place to live.
Taipei has outstanding and affordable public transport, great local and international food, lots to see ckurs do, and serves as a great hub for visiting the rest of Asia.
There is a very active and passionate scientific research community, a keen collaborative spirit, and high professional standards. Alternatively, students may contact with any questions: Identification of extracellular matrix-derived therapeutic targets and biomarkers in dystrophic epidermolysis bullosa.
The most severe forms are characterized by soft tissue fibrosis, which significantly contributes to disease morbidity and drives the ed cause of death in severe DEB, that is cutaneous squamous cell carcinoma cSCC. Some efforts to develop causal therapies have been successful but larger implementation is hampered by concerns surrounding efficacy, delivery, safety and costs. An alternative, which has shown preclinical success is to target changes occurring subsequent to skin fragility.
The innovative nature of this proposal is to comprehensively analyze the main breeding ground of disease complications linked to fibrotic dermal ECM, to better understand how it is established and to derive much-needed biomarkers of disease progression.
These studies will also pave the way towards the identification of novel relevant therapeutic targets, which could help to control aberrant skin remodeling and turn a severe disease into a milder disease. The PhD student will be in charge of the analyses of skin cultures and biopsies using electron microscopy, immuno-detection and proteomics. Both shotgun and targeted MRM proteomic approaches will be used and one major objective will be to adapt specific protocols allowing the enrichment of extracellular matrix proteins in tissue samples.
Applicants should submit their bioxhimie application file CV, motivation letter and references by email to one of the two labs before January 8, All the relevant information can be found on the website of the conference immunology-conference.

With an ageing population, the thematics Ageing and improvement of the quality of life is a primary challenge of the society, both at the biochimiw and european level.
Edentulism is prevalent in ederly patients and the current treatment is the use of removable protheses based on structurald jaw regions. Nevertheless, the close and extended contact of prosthetic intrados with fibromucosa and the transmission of occlusal strengths trough the prosthesis leads to a weakening of supporting tissues in the medium to long term.
This embrittlement may be accompanied by pain, compromising the proper integration of prostheses.
In geriatics, the peculiar weakness of bearing surfaces, connected to physio-pathological conditions as well as the decrease of adaptability and resistance further complicate the biomechanical integration of this kind of prosthesis. It has been shown that chronical ageing induces a decrease of resiliency and hydration of oral mucosa, associated with a decrease of epithelium thickness; nevertheless few studies have been performed at the molecular and supramolecular level to characterize this mucosa, and even fewer on the structural and mechanical evolution with ageing.
FTIR  and Raman  analyses on animal mucosa are promising techniques of characterization on such tissues, as well as dielectric analysis used to discriminate between safe and pathological mucosa . The objective of this work is to adapt these techniques to scan the physical structure and dynamics of mucosa in order to extract vibrational, thermal, mechanical and dielectric markers and to follow vlucides evolution with ageing.
Thornhill, Use of electrical impedance spectroscopy to detect malignant and potentially malignant oral lesions, Int. Biochemistry — Structural Biology Laboratory: Sylvie Ricard-Blum Doctoral school: Description Scientific background and rationale: Lysyl oxidase structuralw an amine oxidase, which is secreted as a proenzyme and catalyzes the first step of collagen and elastin cross-linking in the extracellular matrix ECM.
Its proteolytic activation releases the N-terminal propeptide, which is involved in ECM assembly, acts as a tumor suppressor, inhibits cell signaling, and stimulates adipogenesis. The propeptide is intrinsically disordered and may fold upon binding to its partners.
Preliminary interaction data have been obtained by the team for the propeptide. The aims of the project is i to identify extracellular and membrane partners of the propeptide in order to determine if it has further functions, ii to study if and how it interferes with ECM enzymatic cross-linking, iii to characterize the 3D structure of the complexes formed by the propeptide and its partners, and iv to determine the impact of the RQ gluciees, which inhibits the pro-adipogenic and anti-tumoral activities of the propeptide, on the above processes.
Description of the project methodology: The propeptide and its potential partners will be expressed under a recombinant form in prokaryotic and eukaryotic cells. The interactions glucids the purified proteins will be identified and characterized kinetics and affinity by Bio-Layer Interferometry. The structure of supramolecular complexes will be studied by small-angle X-ray scattering, small-angle neutron scattering and cryo-electron microscopy.
Expected results and perspectives: This project will allow to determine if the propeptide interacts via different molecular recognition processes to its different partners and to decipher the molecular mechanism s underlying its role in ECM assembly and cross-linking, adipogenesis and cell signaling. It will also give molecular insights on the effect of the RQ mutation, which is associated with an increased risk of breast cancer.

The open competitive recruitment process is in two steps: Understanding the mechanisms of dysregulated collagen turnover in skin wound healing pathologies. Biochemistry, cell biology, proteomics Laboratory: Group Metalloproteinases and Tissue Remodeling C.
Scientific background and rationale: Skin wound healing is a complex and tightly regulated process gluvides aims strucutrale restoring skin structural and mechanical integrity. Cojrs process can be defective in a number of pathological contexts linked to ageing, genetic or acquired diseases and lead to non-healing or fibrotic wounds1. Among the numerous pathways which contribute to wound healing pathologies, the imbalance between the synthesis and degradation of fibrillar collagens is known to play a crucial role.
The main objective of the PhD project is to analyze the molecular mechanisms controlling collagen assembly and degradation in normal and defective skin wound healing. Skin biopsies and skin cells originating from mouse models and patients material will be analyzed using a large variety of techniques biochemistry, shotgun and targeted proteomics, imaging techniques, molecular biology, western blots.
The rare genetic disease dystrophic epidermolysis bullosa DEB will be used as a model of defective skin wound healing involving clear signs of dysregulated collagen turnover2 in collaboration with A. The first step will be to characterize the main features of the collagen network in normal and disease samples. Then, the expression and activity of the main proteins involved in the regulation of collagen assembly and degradation3,4 will be analyzed to identify potential targets for therapeutic intervention.
The results from this study will provide important information on the mechanisms which are dysregulated in DEB and in the large number of diseases which also display alterations of collagen turnover. The main perspectives are to identify new biomarkers of DEB progression and to design novel evidence-based therapeutic approaches of DEB which could also be extended to other skin wound healing pathologies.

The extracellular matrix ECM has long been considered a structural element whose primary role was to define the three-dimensional architecture of tissues.
It is now apparent that the ECM is a dynamic structure that undergoes remodeling during tissue morphogenesis and disease to regulate diverse cellular processes, including cellular differentiation, migration and proliferation. As pointed out coyrs the editorial by Stephen Hewitt, the study of the ECM is demanding due to the complexity of the research. Until recently, the lack of the tools required to study the ECM added to the demanding nature of this research.
Through the enhancement of existing and development of new research tools dr animal models, recent studies show that the ECM contributes to the extracellular-control of numerous cellular processes, providing clear evidence of its critical role in regulating tissue morphogenesis and patterning, tissue homeostasis, and pathogenesis of acute and chronic diseases. Over the past 15 to 20 years, scientists studying innate immunity have focused on and learned a great deal about the genetic- signaling- and cellular-mechanisms regulating the innate immune response.
With increased recognition that extracellular-control of cell function is important, investigators are now providing evidence that specific components of the ECM regulate many of the key processes required for the proper function of ds immunity and tissue inflammation. This includes but is not limited to activation, differentiation, migration, proliferation, and death of immune cells. Due to the emerging evidence that extracellular-control of innate immunity is strucrurale, a goal of this special issue is to detail how specific dtructurale of the ECM — proteoglycans, glycosaminoglycans, and tenascin-C — regulate immune cell structrale.
To accomplish this goal, the editors and authors of this special issue have included reviews focused on specific glucieds. A second review focuses on the ability of proteoglycans and specifically their glycosaminoglycan GAG side chains to bind to and provide fine-control of chemokine function and leukocyte migration in tissues. To provide a broader view on the role of the ECM in regulating tissue inflammation, several reviews describe how proteoglycans and GAGs shape the innate immune response in lungs, kidney, brain and intestines.
It is our hope that the information included in this special issue of the Journal of Histochemistry and Cytochemistry provides scientists with a better understanding of the importance of the ECM in providing fine-control of innate immunity.
