The present invention pertains to methods and compounds useful in a therapy involving the administration of immune cells to a patient. The method of the invention involves the modification of cells of the immune system with agonists or antagonists of immune regulators such as Interleukin-10 (IL-10) or IL-6, in order to enhance and improve the immunological potential of the immune cells for therapy. Cells modified according to the method of the invention can be administered to a patient to support a treatment of proliferative diseases such as cancer or autoimmune disorders.

The invention is in the field of immunotherapy. The present invention provides antibodies useful in therapeutic and diagnostic applications targeting human SIRPa, said antibodies enhancing the cross-presentation of antigens to T cells. The invention also provides antibodies against specific isoforms of SIRP a and able to disrupt the interaction between those isoforms of SIRP a and human CD47 for use in treating or preventing a disease, or diagnostic applications, and methods for producing and/or selecting anti-human SIRPa antibodies that bind with different affinities to various isoforms of human SIRP members.

The present invention relates, in part, to methods of treating cancers using combinations of anti-BTNL2 and anti-immune checkpoint therapies.

The present disclosure is directed to dual specificity antibodies which may bind to PD-L1 or PD-L2 and methods of using such antibodies to treat cancers, such as those that express or overexpress PD-L1 or PD-L2.

The present invention relates to single domain antibodies comprising at least one modification relative to the 4D5 antibody scaffold or human germline VH3 domain, the modifications selected from the group consisting of H35D, A78V, S93V, S93G and W103R, with the position numbering being according to the Kabat numbering scheme. Disulfide-free variants further comprise at least one additional modification selected from the group consisting of C22S, A24I, A24L and C92T, and with the proviso that at least one of C22S and C92T is present. Further encompassed are the multi-modular antibody molecules and antibody conjugates comprising single domain antibodies, as well as methods for producing them. The invention in particular provides a library of the single domain antibodies or multi-modular antibody molecules and a method for selecting an antibody that binds an antigen.

The present invention includes compositions and methods for the expression, secretion and use of novel compositions for use as, e.g., vaccine and antigen delivery vectors, to delivery antigens to antigen presenting cells. In one embodiment, the vector is an anti-CD40 antibody, or fragments thereof, and one or more antigenic peptides linked to the anti-CD40 antibody or fragments thereof, including humanized antibodies.

Many disorders wherein inflammation is a hallmark such as rheumatoid arthritis, sepsis, or cancer, are chronic and impose a significant burden on family and society due to their high morbidity and mortality. Each year the United States government spends $2.6T to treat chronic Inflammatory diseases, which are linked to 70% of the deaths every year. Protein therapeutics, such as anti-TNF antibodies that selectively block the TNF cascade, have become the mainstay therapy for the management of chronic inflammatory diseases. Despite the promise of these early studies, concerns about the side effects of these protein drugs, including induction of auto-antibodies and immuno-suppression, may limit the applications to disease treatments. Thus, there is a need to develop new drugs and delivery systems for the prevention and treatment of inflammatory diseases. The present invention relates to extracellular vesicle composition, system, and methods for treating Toll-like receptor-driven inflammatory disease.

The invention relates to the identification of a highly stable single domain antibody scaffold (hs2dAb) and its use in generating synthetic single domain antibody library (hs2dAb-L1). The invention also relates to antigen-binding proteins comprising said stable single domain antibody scaffold and their uses, in particular as therapeutics.

The invention relates to protein-based T-cell receptor knockdown, and its use in T-cell therapies.

The present invention relates to a method for the mass-production of exosome comprising a cargo protein, a vector for preparing the exosome, exosome including a cargo protein prepared by the method, and a method for loading the cargo protein to cytosol by using the exosome prepared thereby. According to the method for preparing an exosome comprising a cargo protein provided by the present invention, the exosome loaded with a cargo protein can be produced with a high yield, so that it can be used broadly in the treatment of disease using the exosome.
