Der volle Inhalt der QuelleChronic inflammatory diseases require new therapeutic strategies. In this context, albumin-based biomaterials, loaded with dexamethasone and infliximab, have been developed in the form of membranes, micro-, and nanoparticles. These biocompatible materials have demonstrated a reduction in several inflammatory markers in various in vitro models. Additionally, different polymers have been examined for their anti-inflammatory or pro-apoptotic properties, revealing an interesting role for polyethyleneimine and polyarginine. These new strategies offer an innovative and biocompatible method for delivering anti-inflammatory molecules. They also explore the potential of well-known polymers in regulating inflammation. By combining various complementary anti-inflammatory mechanisms, these approaches show great therapeutic potential

Der volle Inhalt der QuelleSmoking is responsible for 8 million deaths a year worldwide. Currently, smoking cessation is the only solution to lower this mortality, but is made difficult by nicotine addiction. In recent years, new nicotine delivery devices have come onto the market: the electronic cigarette (e-cig) and heated tobacco. Although they are generally perceived as healthier alternatives to cigarettes, their precise impact on human health remains to be determined.The first objective of this thesis was to analyze the chemical composition and the in vitro toxicity of e-cig emissions of different powers (a second-generation model and a third-generation model (Modbox) set at low power, Mb18W, or high power, Mb30W) and heated tobacco emissions to compare them to cigarette smoke. We have been able to show that heated tobacco generates much less carbonyl compounds and PAHs than cigarettes, but much more than e-cig, regardless of the model. Consistently, the exposure of human bronchial epithelial cells (BEAS-2B) cultured at the air-liquid interface to the emissions from the different devices showed that heated tobacco emissions induced less cytotoxicity than cigarette smoke, but much more than e-cig emissions. In addition, exposures to 12 puffs of heated tobacco or 120 puffs of e-cig induce oxidative stress and the secretion of some pro-inflammatory cytokines. Similar effects were observed for cigarette smoke but only after one puff. Interestingly, for e-cig, we have demonstrated that the amount of carbonyl compounds emitted and induced oxidative stress increase with the power of the device.The second objective of this doctoral project was to evaluate on a mouse model the long-term respiratory toxicity of aerosols generated by a third-generation model of e-cig. BALB/c mice were nose-only exposed for 4 days, 3 months or 6 months to Mb18W or Mb30W emissions or to cigarette smoke. Our in vivo experiments have shown that, on the one hand, e-cig emissions generated at 18 W and 30 W were responsible for epigenetic modifications inducing long-term DNA hypermethylation and deregulation of certain miRNAs at all exposure times, but that, on the other hand, only those generated at 30 W were capable of causing oxidative DNA damage, without leading to chromosomal aberrations or gene mutations. Transcriptomic data obtained after 6 months of exposure to e-cig emissions have shown the deregulation of several signaling pathways involved, in particular, in the inflammatory response, oxidative stress and metabolism of carbonyl compounds and, in particular, of propylene glycol metabolites. However, the low number of genes impacted in each of these pathways does not guarantee that the observed deregulations have a real biological impact. By comparison, cigarette smoke induced, under the same exposure conditions, the deregulation of a greater number of signaling pathways, particularly in relation to inflammation and PAH metabolism, each involving a larger number of genes.Overall, our chemical and in vitro analyses suggest that heated tobacco emissions are less toxic than conventional cigarette smoke but much more harmful than those of e-cigs, regardless of their power. Moreover, the in vivo experiments described in this work did not reveal a proven long-term toxicity of e-cig emissions. However, a more in-depth study of our transcriptomic data and their comparison with future complementary results from histological analyses of exposed animals, their respiratory function and their pulmonary and systemic inflammatory response should allow us to confirm or invalidate this preliminary conclusion

Der volle Inhalt der QuelleThis thesis highlighted the importance of lipid-based carriers and their pharmaceutical implications in the delivery of drugs of different nature for dermal and oral administration. The general introduction provided an overview of the types of lipid-based delivery systems with more emphasis on solid lipid nanoparticles ( SLN ) and lipid nanocapsules ( LNC ). In the first part, Clobetasol propionate ( CP )-loaded SLNs were prepared to improve the performance of long term topical corticosteroid therapy. Skin permeation ex-vivo data indicated that the skin retention of CP increased using the SLN test hydrogel formulation more than that a commercial gel. The second part focused on LNCs. Chapter 1 of this part aimed at encapsulating the hydrophilic macromolecule, fondaparinux ( F ), into LNCs by a novel patented two microemulsion ( ME ) strategy. This is based on the incorporation of a precarrier F-loaded ME into a second ME prepared using the phase inversion temperature plus temperature cycling methodology. LNCs formulated using Imwitor/Span were the best ( 59 nm and 48% incorporation efficiency). Chapter 2 aimed at enhancing the loading of anionic F by using cationic LNCs (~50 nm and 80-100% entrapment efficiency). In vivo study in rats administered F-loaded LNCs orally in comparison with a solution market product demonstrated that caionic LNCs significantly increased F bioavaibility and anti-factor Xa effect in a dose-dependent fashion. Data provided a proof of concept for the potential oral bioavailability of F. This offers great promise for a more convenient chronic anticoagulant therapy replcing the currently used injections

Der volle Inhalt der QuelleThis work presents the synthesis of biocompatible and biodegradable amphiphilic copolymers for the formation of anticancer drug delivery systems. These copolymers consist of a poly-(ε-caprolactone) (PCL) chain, a biocompatible and biodegradable hydrophobic polyester, on which hydrophilic oligomers of dextrane or chitosane are grafted. These new copolymer structures are called “reverse” structures, the “classic” ones being made of a polysaccharide chain with PCL grafts. The PCL chain was propargylated via an anionic method developed by our team, while azide functions were grafted on oligosaccharides at a chain end of dextrane, but along the chain in chitosan, thanks to its amine functions. Copolymers were obtained by CuAAC click coupling between the activated PCL and oligosaccharides. In the case of chitosan, the amines of the chain allowed the coupling of mannose squarate, a cancer cell targeting agent, as well as a functionalization in the form of thiols which allow coupling by thiol-yne reaction on propargylated PCL. These copolymers form nano objects in aqueous media which, in the case of the PCL-g-dextrane structure, are forming micelles that encapsulate doxorubicin, which is further released in a pH- dependent way. Biological studies have shown that these charged micelles are toxic to cancer cells and not to healthy cells and are preferentially internalized by cancer cells. These results demonstrate a high degree of selectivity of action against tumor cells

Der volle Inhalt der QuelleVaccination, especially in animal species, remains already an efficient tool in the prevention of infectious diseases. The carrier and immunostimulant properties of adjuvant allow increasing the action of antigen which, alone, is not enough capable to induce a long and strong immune response in host. The unique properties of chitosan, a biocompatible and biodegradable natural polymer, offer a choice material to elaborate new generations of adjuvant such as nanoparticles or hydrogels.This PhD works was focus on the development of chitosan-based adjuvant for animal species. The preparation of chitosan-based viscous solutions, with a polymer concentration from 0.2 to 0.75 % (w/v) mixed with different kind of antigens such as live attenuated bacteria, live attenuated or inactivated virus and a recombinant protein allowed obtaining an immune response in the studied animals. Moreover, the observation of animals during the protocol or in post-mortem inspections indicated a satisfying safety and resorbability. In vitro experiments were also conducted developing a syringeable and injectable in situ gelling chitosan-based hydrogel containing a model protein, destined to standard injection system. The slow release of antigen in the host should interact with the immune system longer increasing the final protection against diseases

Der volle Inhalt der QuelleNanotechnology became for several years a major development in the areas of diagnostics, imaging, drug delivery, therapeutic monitoring, and tissue engineering. The administration of non-injectable products in their free form or with high toxicity, can be facilitated by the use of nanocarriers, changing their distribution. They therefore reduce the doses administered, limit side effects and direct the contents of the vector (contrast agent, drug) to a target organ or tumor, by presenting to the surface thereof targeting molecules of these areas specific.This thesis fits into this theme : we have explored the possibilities of forming chemical gels based on lipid nanoparticles which are composed of an oily heart can encapsulate small hydrophobic molecules and a layer of surfactants allowing stabilization of the droplets in the aqueous phase.We have synthesized several PEGylated functionalized surfactants (thiol, maleimide, amine, and oxyamines ONB-maleimide). synthesis protocols of these surfactants are refined and repeatable.These surfactants were incorporated into the surface of lipid nanoparticles. The functionalized nanoparticles thus obtained have been characterized and the functions present at their surface are highlighted.Different kinds of chemical gels stable, resistant to dilution, fast and controllable manufacturing have been developed.These chemical gels can be used in the future for encapsulating proteins or drugs

Der volle Inhalt der QuelleGene therapy is a molecular medicine and a very powerful tool for the treatment of several diseases such as inherited disorder and cancer. Nucleic acids must penetrate into cells in order to interact with their genetic material. Currently the main limitation to the application of this treatment towards clinics is the lack of robust, safe and efficient gene delivery vectors. The two major classes of vectors are those based on recombinant viruses and those based on non-viral systems. Viral vectors are the most efficient and used in several clinical trials, however they can elicit a strong immune reaction and they possess high cost of production. Non-viral vectors are less immunogenic and can be easily produced on a large scale. A large variety of both cationic lipids and polymers have been developed due to their ability to interact spontaneously with negatively charged nucleic acids to form complexes. However these positively charged complexes can present some toxicity due their non-specific interaction with cell membranes and seric proteins. This is the main limitation for their clinical use. For this purpose, new vectors, neutral or anionic, have to be developed in order to diminish the cytotoxicity and increase the circulation time. Nucleotide-lipids (NLs) are bio-inspired amphiphilic hybrid molecules composed of a hydrophilic nucleotidic moiety and a hydrophobic lipophilic moiety. These molecules are able to self-assembly to form supramolecular structures which possess particular physico-chemical properties due to the chemistry of their polar head. These molecules can interact with a nucleic acid by Watson-Crick base pair interactions, however they are not sufficiently strong to form a stable complex that can be used for a biological application. A new chemical family of hybrid amphiphile, amino acid-nucleotide-lipids (ANLs), has been developed in order to increase the interactions and the stability of the complex thank to the presence of the amino acid on the polar head. Herein, we have synthesized novel amino acid-nucleotide-lipids, presenting phenylalanine (or glycine) and thymidine residues and saturated (dimiristoyl) or unsaturated (dioleoyl) diacyl glycerol lipid. The morphology and the structural organization of the supramolecular objects formed by these molecules was studied by dynamic light scattering (DLS), cryo-electron microscopy (cryo-TEM) and small angle X-ray scattering (SAXS). These studies allowed investigating the relation between the chemical structure and the physic-chemical properties. The amino acids, inserted at the 5′ position of the nucleotide-lipids, stabilize multilamellar systems, whereas unilamellar vesicles are formed preferentially in the case of nucleotide-lipids. Both NLs and ANLs exhibit weak interactions with complementary polyA RNA as revealed by isothermal titration calorimetry (ITC) investigations, however they are not sufficiently strong to form a stable complex that can be used for a biological application. The use of multivalent cations, such as Ca2+, which bridge the phosphate groups on the lipid polar heads with those of the backbone of nucleic acids, to form ternary complexes, has been investigated by SAXS. Finally, a structural study, by DLS and cryo-TEM of NLs aggregates in aqueous solutions as a function of ionic strength and surfactant concentration, has been conducted in order to investigate the different morphologies of the systems

Der volle Inhalt der QuellePoor tumor penetration and high toxicity of anticancer drugs, together with the developed drug resistance constitute challenging hurdles for cancer therapy. The application of nanotechnology for anticancer drug delivery is expected to address these issues and bring new hope for cancer treatment. In the first part of my PhD thesis, we used a new tumor-penetrating peptide, CRGDK, to conjugate onto the surface of doxorubicin encapsulated DSPE-PEG2000 nanomicelles. The CRGDK peptide conjugated on the nanomicelles triggered specific binding to Nrp-1 receptors, leading to enhanced cellular uptake and anticancer activity in vitro. The in vivo results further confirmed that the CRGDK-decorated nanomicelles could efficiently accumulate and penetrate into deeper tumors. In the second part of my PhD thesis, we established an original nanomicellar drug delivery system based on an amphiphilic dendrimer (AmDM), which could generate supramolecular micelles to effectively encapsulate the anticancer drug doxorubicin (DOX) with high drug loading capacity (> 40%), thanks to the unique dendritic structure creating large void space for drug accommodation. The resulting AmDM/DOX nanomicelles are able to specifically accumulate at tumor sites via EPR effect and penetrate deeper into tumor tissues thanks to their small size. Most importantly, these nanomicelles exhibit significantly improved anticancer activity and reduced systemic toxicity, and are very effective even towards drug resistant cancers by virtue of their macropinocytotic cell uptake mechanism and their ability to bypass cell drug efflux pumps
