The present invention relates to Chimeric Antigen Receptors (CAR) that are recombinant chimeric proteins able to redirect immune cell specificity and reactivity toward selected membrane antigens, and more particularly in which extracellular ligand binding is a scFV derived from a CD123 monoclonal antibody, conferring specific immunity against CD123 positive cells. The engineered immune cells endowed with such CARs are particularly suited for treating lymphomas and leukemia.

The present invention relates to a novel antibody against HERV-K envelope that targets a conserved region not affected by glycosylation or by native conformation, and its use in diagnostics and/or is therapy.

The technology described herein is directed to immunotherapy agents for autoimmune disease, cancer, or allergy. In some embodiments, the immunotherapy agent comprises a bispecific antibody construct that specifically binds FcRn and a Type I or Type II Fcγ T receptor. In some embodiments the bispecific antibody construct is a DvD-Ig construct. Also described herein are methods for treating autoimmune disease, cancer, or allergy, comprising administering an effective amount of a bispecific antibody construct to patient in need thereof.

Provided herein are antibodies that selectively bind to complex comprising a non-classical HLA-I (e.g. HLA-E) and a neoantigen having variable heavy chain domains (VH), variable light chain domains (VL), and complementarity determining regions (CDRs) as disclosed herein, as well as methods and uses thereof.

The present invention provides a method for recovering a human VH3 domain-containing antibody in monomeric form. In particular the present invention provides a new method that allows recovery of monomeric human VH3 domain-containing antibodies from a mixture containing monomeric and multimeric forms of the antibody.

The present disclosure relates to multi-specific molecules which are capable of simultaneously binding at least two different target antigens or epitopes. The molecules comprise at least one binding domain molecule (BDM) which binds to a first target antigen or epitope, the BDM being modified for selective binding to a heterologous target, coupled to a pharmacologically active protein or peptide which is an antibody or antigen-binding fragment thereof or a non-antibody protein or peptide which binds to a second target antigen or epitope, the BDMs being coupled to a C-terminus of a polypeptide present within the pharmacologically active protein or peptide.

The invention provides CCL14 antibodies.

Provided is an isolated TrkB agonist antibody that binds to an epitope contained in one of the extracellular domains of TrkB and is capable of activating TrkB, wherein the extracellular domains comprises extracellular D1, D2, D3, D4, D5 domains and juxtamembrane domain of TrkB. Methods of using the TrkB agonist antibody in treating or reducing the risk of a TrkB associated conditions in a subject, wherein said condition is selected from cell differentiation, synaptic development, neural injury repairing and/or neurite branching.

Described herein are single vectors that, when expressed in cytolytic immune cells, results in both the expression of (1) a CAR targeting tumor-associated antigens and (2) secretion of a bispecific antibody that on one end recognizes NKG2D expressed on both innate and antigen specific cytolytic immune cells and on the other end targets tumor associated antigens. Unexpectedly, these modifications to the T cells result in enhanced survival and proliferation in vivo. Thus, therapeutic and diagnostic uses are disclosed.

Provided herein are DLL3 binding proteins and DLL3 targeting multispecific proteins (e.g., DLL3 targeting trispecific protein) comprising a domain binding to CD3, a half-life extension domain, and a domain binding to DLL3 (such as a DLL3 binding protein as provided herein). Also provided are pharmaceutical compositions thereof, as well as nucleic acids, recombinant expression vectors and host cells for making such DLL3 binding proteins, DLL3 targeting trispecific proteins. Also disclosed are methods of using the disclosed DLL3 binding proteins, DLL3 targeting trispecific proteins in the prevention, and/or treatment diseases, conditions and disorders.
