This invention, inter alia, relates to CD19 binding agents and methods of using such CD19 binding agents for treating disease.

The present invention includes compositions and methods for the expression, secretion and use of novel compositions for use as, e.g., vaccines 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.

Provided are novel human tau-specific antibodies as well as fragments, derivatives and variants thereof as well as methods related thereto. Assays, kits, and solid supports related to antibodies specific for tau are also disclosed. The antibody, immunoglobulin chain(s), as well as binding fragments, derivatives and variants thereof can be used in pharmaceutical and diagnostic compositions for tau targeted immunotherapy and diagnosis, respectively.

The present invention provides pharmaceutical formulations comprising a human antibody that specifically binds to human interleukin-4 receptor (hIL-4R). The formulations may contain, in addition to an anti-hIL-4R antibody, at least one amino acid, at least one sugar, or at least one non-ionic surfactant. The pharmaceutical formulations of the present invention exhibit a substantial degree of antibody stability after storage for several months.

Monoclonal neutralizing antibodies are disclosed that specifically bind to the HIV-1 gp41 membrane-proximal external region (MPER). Also disclosed are compositions including the disclosed antibodies that specifically bind gp41, nucleic acids encoding these antibodies, expression vectors including the nucleic acids, and isolated host cells that express the nucleic acids. The antibodies and compositions disclosed herein can be used for detecting the presence of HIV-1 in a biological sample, or detecting an HIV-1 infection or diagnosing AIDS in a subject. In additional, the broad neutralization breadth of the disclosed antibodies makes them ideal for treating a subject with an HIV infection. Thus, disclosed are methods of treating and/or preventing HIV infection.

The present invention provides an antibody or an antigen-binding fragment thereof with binding specificity for human interleukin-1 receptor accessory protein (IL1RAP) wherein the antibody or antigen-binding fragment is capable of inhibiting the binding of antibody ‘CAN04’ to human IL1RAP. The invention further provides the use of such antibodies or an antigen-binding fragments in the treatment and/or diagnosis of IL-1 associated diseases and conditions, including cancers such as acute myeloid leukemia and melanoma.

The present invention relates to anti-transferrin receptor antibodies and methods of their use.

The invention provides anti-oncostatin M receptor-β (OSMR) antigen binding proteins, e.g., antibodies and functional fragments, derivatives, muteins, and variants thereof. OSMR antigen binding proteins interfere with binding of OSM and/or IL-31 to OSMR. In some embodiments, anti-OSMR antigen binding proteins are useful tools in studying diseases and disorders associated with OSMR and are particularly useful in methods of treating diseases and disorders associated with OSMR and binding of OSM and/or IL-31 to OSMR.

The present invention provides antibodies and related molecules that bind to chemokine receptor 4 (CXCR4). The invention further provides antibody-drug conjugates comprising such antibodies, antibody encoding nucleic acids, and methods of obtaining such antibodies. The invention further relates to therapeutic methods for use of these antibodies and anti-CXCR4 antibody-drug conjugates for the treatment of a disorder associated with CXCR4 function or expression (e.g., cancer), such as colon, RCC, esophageal, gastric, head and neck, lung, ovarian, pancreatic cancer or hematological cancers.

A polypeptide encoding a chimeric antigen receptor (CAR) comprising at least one extracellular binding domain that comprises a scFv formed by at least a VH chain and a VL chain specific to an antigen, wherein said extracellular binding domain comprises at least one mAb-specific epitope.
