Collagens are the most abundant proteins in mammals. The collagen family comprises 28 members that contain at least one triple-helical domain. Collagens are deposited in the extracellular matrix where most of them form supramolecular assemblies. Four collagens are type II membrane proteins that also exist in a soluble form released from the cell surface by shedding. Collagens play structural roles and contribute to mechanical properties, organization, and shape of tissues. They interact with cells via several receptor families and regulate their proliferation, migration, and differentiation. Some collagens have a restricted tissue distribution and hence specific biological functions. Source

The present invention relates to a method for preparing by wet spinning a continuous filament based on hyaluronic acid in free acid form, notably soluble in water. The preparation method according to the invention comprises the following steps: a) preparing a spinnable aqueous solution of hyaluronic acid or of a hyaluronic acid salt, preferably a sodium hyaluronate solution; b) extruding said solution to an extrusion die; c) forming the filament by passing the extruded solution into a bath of acetic acid, concentrated to more than 80%, drawing and drying. The invention also relates to a filament based on hyaluronic acid in free acid form, said filament having swelling properties in water and physiological liquids and moreover being solubilizable in water under certain conditions.

The invention relates to a novel use of ultrafine nanoparticles, of use as a diagnostic, therapeutic or theranostic agent, characterized by their mode of administration via the airways. The invention is also directed toward the applications which follow from this novel mode of administration, in particular for imaging the lungs, and the diagnosis or prognosis of pathological pulmonary conditions. In the therapeutic field, the applications envisioned are those of radiosensitizing or radioactive agents for radiotherapy (and optionally curietherapy), or for neutron therapy, or of agents for PDT (photodynamic therapy), in particular for the treatment of lung tumors.
