The present invention concerns methods and compositions for treatment of HIV infection in a subject, utilizing a DNL® complex comprising at least one anti-HIV therapeutic agent, attached to an antibody, antibody fragment or PEG. In a preferred embodiment, the antibody or fragment binds to an antigen selected from gp120, gp41, CD4 and CCR5. In a more preferred embodiment the antibody is P4/D10 or 2G12, although other anti-HIV antibodies are known and may be utilized. In a most preferred embodiment, the anti-HIV therapeutic agent is a fusion inhibitor, such as T20, T61, T651, T1249, T2635, CP32M or T-1444, although other anti-HIV therapeutic agents are known and may be utilized. The DNL® complex may be administered alone or may be co-administered with one or more additional anti-HIV therapeutic agents.

The present invention pertains to engineered extracellular vesicles (EVs) for use in a variety of research, diagnostic, imaging and therapeutic applications. The EVs are engineered to enable incorporation and surface display of various proteins of interest, which may be exogenous and/or endogenous in nature. The coating of EVs is achieved through inventive protein engineering of EV polypeptides, and the present invention thus relates to methods for coating of EVs, EVs per se, as well kits, detection methods, diagnostic applications, imaging and delivery methods based on said engineered EVs.

Aspects of the disclosure relate to antibodies that bind to transferrin receptor (e.g., transferrin receptor 1) and complexes comprising the antibody covalently linked to a molecular payload. Methods of using the antibodies are also provided.

The invention relates to a pharmaceutical composition soluble in an aqueous solution, which is characterised in that it comprises sialoglycosphingolipids; polypeptides selected from the group comprising antibodies, fragments and variants of same; and at least one therapeutically active substance, forming a ternary micellar complex of sialoglycosphingolipid-therapeutically active substance-polypeptide in which the polypeptides are non-covalently associated with the micelles formed by the sialoglycosphingolipid and the therapeutically active substance.

The present invention is directed to a nanoparticle including: a core of a metal chelating polymer, wherein the core is coated with at least two layers of magnetic metal oxide, which are further coated with a protein layer, and at least one active agent bound within or to the nanoparticle, methods for directing or targeting the nanoparticle via a magnetic field to a target tissue, and a computer program for efficiently generating the proper magnetic field for driving the nanoparticle to or into a given target tissue.

The present invention relates to a novel antibody specifically binding to human and mouse L1CAM, and more particularly, to an antibody binding to both human and mouse L1CAM with high affinity, which is prepared by modifying a sequence of an L1 cell adhesion molecule (L1CAM)-specific antibody comprising a heavy-chain variable region of SEQ ID NO. 1 and a light-chain variable region of SEQ ID NO. 5, a polynucleotide encoding the antibody, an expression vector comprising the polynucleotide, a transformant introduced with the vector, a pharmaceutical composition for preventing or treating cancer comprising the antibody, a method for treating cancer using the antibody, a composition for diagnosing cancer comprising the antibody, a kit for diagnosing cancer comprising the composition, a method for providing information for cancer diagnosis using the antibody, and an antibody-drug conjugate prepared by conjugating a drug to the antibody.
