Abstract: The invention relates to a nanoparticle comprising at least one cationic lipid, at least one neutral lipid, and at least one pH sensitive lipid which differs from said cationic lipid, which can be used as a vector for the transport and release of nucleic acids within cells.

Abstract: The present invention is based on the finding that Netrin-(1) is retained in a stickier manner in the cell matrix at the cell periphery of the cancer cells, whereas Netrin-(1) is expressed in adults specifically in some tumors. It is also shown herein that Netrin-(1) is expressed very early during tumor formation. This makes Netrin-(1) an unexpected very specific target for imagery and/or targeted therapy. The present invention thus relates to compounds comprising an anti-Netrin-1 antibody, especially NP(137), a chelating moiety, optionally associated with a radioisotope, and their use either in imagery, diagnosis, especially companion diagnosis, or in targeted therapy. New diagnostic tests, which may be companion tests, and new cancer therapies, that may be combined to the companion test, are also proposed.

Abstract: Described herein is a novel nanocomposite for oral administration for treatment of gastrointestinal disease, e.g., IBD, or injury. The nanocomposite contains nanoemulsion particles (NEs), loaded with an active therapeutic agent, that are then combined with a second component containing a self-assembling peptide(s) (SAP) or peptidomimetic(s) (optionally, the second component is in a powder form). Upon administration, when hydrated at slightly acidic or near-neutral pH, the system self-assembles into a hydrogel matrix enveloping NEs, which then adheres to, and more efficiently delivers, the active agent to the intestinal tract of a treated subject. The nanocomposite can be administered in a capsule dosage form that forms a depot in the stomach or post-stomach.

Abstract: The invention relates to dendritic compounds comprising a chelating, fluorochrome or recognition agent of formula (I), to compositions comprising same, and to uses thereof, wherein in said formula (I): T, L1, D, R, L2, V and n are as defined in the description.
