The present disclosure relates to antibodies binding to tumor discoidin domain receptor 1 (DDR1) and the uses of the antibodies in detecting and treating cancer. Thus, in one aspect, the present disclosure provides an isolated monoclonal antibody or an antigen-binding fragment thereof that binds specifically to DDR1. In certain embodiments, the antibody or antigen-binding fragment, when bound to DDR1, modulates the activity of DDR1, i.e., suppresses DDR1.

Embodiments of the present invention relate to compositions and methods for activating canine OX40 to treat a condition in dogs. In certain embodiments, the condition can be cancer or an immunosuppressed condition in dogs and OX40 activation treats, ameliorates or prevents onset or progression of the condition. In other embodiments, compositions disclosed herein generally relate to compositions including, but not limited to, activating antibodies having specific affinity for OX40 for inducing activity of canine OX40. In other embodiments, compositions disclosed herein can be used for treating certain cancers or an immunosuppressed condition to treat the cancer or alleviate immunosuppression in dogs. In certain embodiments, other immune activators can be administered in combination with OX40 activating antibodies such as Toll-Like Receptor (TLR) ligands alone or in combination with other non-specific immunostimulant agents.

The present invention provides a tumor immunotherapy target and use thereof, specifically provides use of the LSECtin expressed by infiltrating tumor-associated macrophage and BTN3A3 expressed by tumor solely or in combination as a target in tumor immunotherapy, and further provides a substance capable of inhibiting the activity of LSECtin expressed by infiltrating tumor-associated macrophage, the activity of BTN3A3 expressed by tumor, or the interaction of the LSECtin with BTN3A3, including RNA molecules, fusion protein BTN3A3-Ig, and monoclonal antibody 5E08, which can be used as an active ingredient to prepare a tumor immunotherapy drug, and is suitable for industrial applications.

Provided is an anti-canine PD-1 antibody, capable of binding with canine PD-1 and comprising three light-chain complementary determining regions (CDR1-3) or a conservatively modified variant maintaining its function and/or three heavy-chain complementary determining regions (CDR1-3) or a conservatively modified variant maintaining its function. Further provided is an application of the anti-canine PD-1 antibody in the preparation of medicines for treating canine cancers.

The present invention relates to monoclonal anti-Sortilin antibodies which have been found useful in correcting a deficient level of progranulin (PGRN). In particular, these antibodies can be used in the treatment of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS).

Provided are compositions and methods for producing modified non-human animals that produce heavy chain only antibodies (HCAbs), and modified non-human animals produced by the compositions and methods, and isolated HCAbs produced by the HCAbs.

The invention provides for an isolated antibody that specifically recognizes a galactan-III epitope of the lipopolysaccharide (LPS) O-antigen structure of Klebsiella pneumoniae, which epitope is incorporated in galactan-III repeating units, wherein the galactan-III repeating unit is a branched galactose homopolymer of Formula (I). The invention further provides for a pharmaceutical or diagnostic preparation comprising said antibody, and a method of producing said antibody. ##STR00001##

The present invention relates to a research tool for structural biology, in particular to enhance the determination of the three-dimensional structure of biological macromolecules. More specifically, the invention serves to improve the overall feasibility of structure determination providing higher resolution and better quality of the three-dimensional structures of proteins by complex-formation with a novel fusion polypeptide.

Disclosed are antibodies, including antibody drug conjugates, that specifically bind to NTB-A. Also disclosed are methods for using the anti-NTB-A antibodies to detect or modulate activity of (e.g., inhibit proliferation of) an NTB-A-expressing cell, as well as for diagnoses or treatment of diseases or disorders (e.g., cancer) associated with NTB-A-expressing cells. Further disclosed is a method of treating multiple myeloma using an anti-NTB-A antibody drug conjugate, which optionally includes an anti-NTB-A antibody as disclosed herein.

Disclosed is a SIRPα-targeting antibody or an antigen-binding fragment thereof, comprising a light chain variable region and/or a heavy chain variable region. The antibody or the antigen-binding fragment thereof binds to human SIRPα-V1 and human SIRPα-V2, but weakly or does not bind to human SIRPβ and SIRPγ, does not bind to human T cells, and has the function of blocking the binding of SIRPα to CD47. Further disclosed are a bispecific antibody comprising same, a method for preparing the antibody or the antigen-binding fragment thereof and an application thereof. The unique properties of the disclosed antibody or the antigen-binding fragment thereof enable same to be more suitable for the development of drugs for an antibody or antigen-binding fragment against a human SIRPα target. As a candidate drug, same can be administered alone or in combination, providing a new or even better choice for the combined immunotherapy of tumors.
