Abstract:
This investigation looks at the hydrodynamic characterisation of both covalent and non-covalent protein polysaccharide complexes in the context of novel treatments and healthcare. New techniques were employed and evaluated, such as the MUTLTISIG and SEDFIT-MSTAR algorithms for sedimentation equilibrium analysis, as well as the Extended Fujita Approach for sedimentation velocity. Other characterisation techniques were used such as viscometry, density measurement, Dynamic Light Scattering and Size Exclusion Chromatography coupled to Multi Angle Light Scattering.

Abstract:
Polysaccharides are one of the most abundant and diverse families of natural polymers, and have an incredibly wide range of natural functions including structural reinforcement, energy storage, aqueous rheology modification, and communication and identity. Application of native polysaccharides like cellulose as sustainable materials is limited by some inherent drawbacks such as insolubility in common solvents including water, and poor dimensional stability. To increase their functionality and utility, researchers have sought to tailor the chemical and physical properties of cellulose and other

Myasthenia gravis (MG) is an autoimmune disorder in which auto-antibodies directed at the acetylcholine receptors (AChR) of the neuromuscular junction (NMJ) block, alter or destroy their targets. The anti-AChR antibodies cause activation of the classical complement pathway leading to inflammatory injury at the NMJ. Decay Accelerating Factor (DAF), a member of complement regulatory proteins, prevents activation of autologous components of complement pathways. The absence of DAF, in knock-out mouse models, has been shown to significantly increase the susceptibility to experimental autoimmune MG.

Abstract:
L’association de polysaccharides naturels et de polypeptides recombinants de type élastine (ELP) dans des structures de copolymères à blocs doit permettre d’accéder à des matériaux possédant des propriétés d’auto-assemblage sous l’action de stimuli et potentiellement bioactifs. Nous avons réalisé et présentons ici la synthèse d'une série de bioconjugués polysaccharide-b-ELP, dans lesquels 4 polysaccharides hydrophiles différents ont été couplés à l'extrémité N-terminale de l’ELP par "chimie click".Ces bioconjugués ont été caractérisés par RMN 1D et 2D, SEC et FTIR. Leur thermo-sensibilité et l
