Full textNow that diabetes reaches pandemic proportions, this thesis focuses on the effect of T2DM on bone. Very few studies document the effect of T2DM on maxillo-facial bone and their endomembraneous repair.After a short review on bone, diabetes and animal study models, we will showcase our results of the impact of T2DM on, (i) vascular and bone repair of calvarial defects in ZDF rats; (ii) the vascular and bone microarchitechture of ZDF rat’s femur; (iii) the secretome and angiogenic properties of zdf rat’s bone marrow stromal cells (BMSC). These studies showed an alteration of bone repair in critical size defects, and an impaired vascular repair in critical and subcritical T2DM defects. We also found evidences of bone and vascular microarchitechture impairement in ZDF femur. At a cellular level, T2DM BMSCs have an unique angiogenic profile. These findings may contribute to the better understanding of the adverse vascular healing in T2DM and provide successful bone healing therapies for patients with T2DM

Full textGalectins composed a family of soluble lectins implicated in multiple processes. They are characterized by the presence of a carbohydrate recognition domain evolutionary conserved and an affinity for β-galactosides containing sugars. During this thesis, we focused on a protein called galectine-7 whose expression is restricted to stratified epithelia such as the epidermis. Using mouse models with altered expression of galectin-7, our team previously showed that this protein participates in intercellular adhesion and collective cell migration, two key processes in tumour progression and epidermal wound healing. However, the underlying mechanisms remain to be elucidated. Combining different approaches, we discovered that the migration delay observed in the absence of galectin-7 during wound healing could be explained, at least in part, by a reduction of cell coordination and collective cell behaviour of migrating keratinocytes. Moreover, our data showed that galectin-7 directly interact with E-cadherin, a key component of adherent junctions and a major player in collective migration. Surprisingly, this binding did not involve carbohydrate groups. Aiming to precise the role of galectin-7 at adherent junctions, we identified a new function of galectin-7 in the stabilisation of E-cadherin at the plasma membrane. Interestingly, the increased of E-cadherin turnover caused by galectin-7 extinction is also associated to a decreased of the strength of adherent junctions-based intercellular adhesion. Eventually, our experiments indicated that this previously unknown function of galectin-7 required a functional lectin activity, suggesting the involvement of an additional glycosylated actor in this regulation mechanism of E-cadherin dynamics by galectin-7.In conclusion, this thesis allowed to precise the role of galectin-7 in collective cell migration and revealed a novel function of galectin-7 in the regulation of the E-cadherin stability at the plasma membrane. This modulatory effect of galectin-7 on E-cadherin could provide the cell a possible adaptive response to environmental perturbations, as during collective cell migration. Indeed, galectins, because they exhibit rapid redistribution capacities, are good candidates to create adaptive responses

Full textThe skin is an organ densely innervated and vascularized. The establishment of the cutaneous nervous system depends on the secretion of neurotrophic factors by the skin. Meanwhile, the establishment of the vascular network also depends on soluble instructive cues. The work presented in this thesis describes new paracrine interactions. While interactions from skin to sensory neurons for the development of innervation and interactions from sensory neurons to blood vessel for vasodilation of the vasculature are described elsewhere, we demonstrate here the influence of neurotrophic factors on the vascular network and the influence of sensory neurons on the reepithelialization of wounds. Our overall goal was to clarify the influence of the neurotrophic and nervous contexts on the homeostasis of the skin. First, we hypothesized that in addition to their neuronal contribution, neurotrophic factors also influence the vascular network. We show that NGF, BDNF, NT-3 and GDNF are expressed in the epidermis, while NGF and NT-3 are expressed by fibroblasts and BDNF by endothelial cells. Finally, Schwann cells produce NGF, BDNF and GDNF. We show that these peptides are very potent angiogenic factors using a model of human endothelialized reconstructed dermis by tissue engineering. An increase of 40 to 80% of the number of capillary-like tubes was observed after the addition of 10 ng/ml NGF, 0.1 ng/ml of BDNF, 15 ng/ml of NT-3, and 50 ng/ml of GDNF. This angiogenic effect depends on the neurotrophic factor receptor TrkA, TrkB, GFRa-1 and c-ret that are all expressed by human endothelial cells. This effect was blocked by adding the Trk inhibitor K252a for NGF, BDNF and NT-3. Second, we hypothesized that sensory neurons directly influence reepithelialization by secreting the neuropeptide substance P. To verify this, we developed a new model of reepithelialization. It consists of a perforated epidermal equivalent expressing a green fluorescent protein stacked on a dermal equivalent that is used as a bed for reepithelialization. The reconstructed skin is endothelialized and innervated or not with sensory neurons of mouse. Sensory neurons produce substance P in the model and keratinocytes express the NK1 cell receptor for substance P. Keratinocyte migration was quantified by fluorescence. Reepithelialization was faster in presence of sensory neurons and we show that substance P contributes to this effect with agonist and antagonist of the NK1 cell receptor. The overall results provide a better understanding of the importance of the neurotrophic and sensory contexts in the skin. Thus, cutaneous innervation does not only contribute to the sensory detection. Our findings may suggest that improving nerve regeneration would improve skin long term tissue homeostasis.
