The present disclosure provides anti-CCR8 antibodies, and compositions and methods of their preparation and use.

The present application relates to anti-PD-L1 antibodies and their use to detect PD-L1 in a sample from a subject. In some embodiments, the subject has been treated with a therapeutic anti-PD-L1 antibody and an anti-PD-L1 described herein does not compete for binding to PD-L1 with the therapeutic anti-PD-L1 antibody. In some embodiments, the anti-PD-L1 antibody is linked to a detectable moiety, such as a fluorophore and the anti-PD-L1 antibody is used to detect PD-L1 in a subject using flow cytometry.

Some embodiments of the invention include virus-like particle (VLP) binding agents, and related polynucleotides, cells, methods of making, and compositions. Other embodiments of the invention include methods of detecting VLPs, parvovirus, erythrovirus or parvovirus B19 using a VLP binding agent and diagnostic methods for parvovirus, erythrovirus or parvovirus B19. Further embodiments include methods for administering VLP binding agents to an animal. Other embodiments include treating parvovirus, erythrovirus or parvovirus B19 infections and other diseases. Additional embodiments of the invention are also discussed.

The invention provides monoclonal antibodies and antigen-binding fragments thereof specific for TNFR2, and methods of using the same to treat cancer or autoimmune disorder, including combination therapy with antagonists of the PD-1/PD-L1 immune checkpoint.

The present disclosure provides TGFβ inhibitor therapy for treating immunosuppressive conditions, such as cancer. Selection of suitable therapy and patients who are likely to benefit from such therapy are also disclosed, as well as methods of treating cancer and methods of predicting and monitoring therapeutic response. Related compositions, methods and therapeutic use are also disclosed.

The invention discloses an antibody that binds an extracellular part of human HVEM on human HVEM-expressing cells, that prevents binding of BTLA to HVEM when the antibody is bound to said extracellular part of HVEM, wherein said antibody displaces BTLA bound to said extracellular part of HVEM. The invention also discloses the use of such an antibody in combating certain diseases.

Described herein are antibody constructs comprising a 41-1BB binding domain and an antigen-binding domain that binds to a tumor-associated antigen (TAA), wherein the 4-1BB-binding domain and the TAA antigen-binding domain are linked directly or indirectly to a scaffold. The scaffold may be an Fc construct with modifications that reduce its ability to mediate effector function.

An anti-B-cell maturation antigen (BCMA)/anti-4-1BB bispecific antibody or an antigen-binding fragment thereof, and use thereof, are provided. The bispecific antibody or an antigen-binding fragment thereof may have high binding affinity to both of a BCMA protein and a 4-1BB protein and may be effectively used to prevent or treat a disease related to BCMA, 4-1BB, or both thereof (e.g., cancer).

Methods of expanding T cells ex vivo comprising contacting the T cells with antibody molecules that bind to TCR Vβ regions are described. T cells comprise one or more nucleic acid molecule encoding an exogenous cellular receptor, for example, a chimeric antigen receptor (CAR) or an exogenous T cell receptor (TCR).

Provided are anti-FGFR2b antibodies or antigen-binding fragments thereof, isolated polynucleotides encoding the same, pharmaceutical compositions comprising the same, and the uses thereof.
