Skin microbiota protects their host from oxidative stress through secreted antioxidant RoxP

Many skin diseases, including psoriasis and basal cell carcinoma, are associated with microbial dysbiosis characterized by reduced C. acnes prevalence. C. acnes is a facultative anaerobic bacterium that is frequently found on the human skin. This bacterium is both an opportunistic pathogen and a commensal organism. Indeed, most individuals are Read more…

Développement d’un modèle cérébral in vitro en 3 dimensions (présentation au congrès de la SCMC)

Véronique De Conto, doctorante chez HCS Pharma, présentera ce jeudi 28 mars à Lille, au congrès annuel de la Société Cerveau et Maladies Cérébrovasculaires, le développement d’un modèle cérébral en 3 dimensions incluant le microenvironnement matriciel pour la recherche de nouveaux médicaments contre la maladie de Parkinson. Introduction : 90% Read more…

The human skin microbiota could promote wound healing

Skin commensals are crucial in the maintenance of the epithelial barrier function, regulation of the host immune system, and prevent invasion of other pathogenic microbes.        In this article, published in September 2018, Burmeister et al show that Staphlylococcus, Streptococcus, Pseudomonas, Corynebacterium, and anaerobes have both beneficial and harmful effects depending Read more…

Influence of the extracellular matrix on cancer cell proliferation and migration

Extracellular matrix (ECM) is known to have an influence on physiological processes and on tumour progression: ECM properties (composition, stiffness) modulate cell proliferation, migration, invasion and epithelial-to-mesenchymal transition (EMT). For example, EMT is inhibited by laminin-rich environment whereas it is promoted in fibronectin-rich ECM (Chen et al 2013. Differentiation 86, Read more…

Breakdown of the extracellular matrix (ECM) promotes increased cell migration via upregulation of glycolysis

Cells have diverse circuitry to sense and respond to extrinsic metabolic signals. Extracellular matrix (ECM) reorganization which is central to both tissue expansion and regeneration. ECM remodeling is also a signature of pathological processes, such as tumorigenesis. In this study from Sullivan et al., they show that increased migration in Read more…
