This invention relates generally to antibodies that bind to human B and T lymphocyte attenuator (BTLA) and uses thereof. More specifically, the invention relates to agonistic antibodies that bind human BTLA and modulate its activity, and their use in treating inflammatory, autoimmune and proliferative diseases and disorders. Suitably, the antibodies also possess an Fc modification that enhances signalling through FcγR2B.

Antibodies and meditopes that bind to the antibodies are provided, as well as complexes, compositions and combinations containing the meditopes and antibodies, and methods of producing, using, testing, and screening the same, including therapeutic and diagnostic methods and uses.

The invention provides anti-cluster of differentiation 3 (CD3) antibodies and methods of using the same.

Provided herein are methods for generating conjugated immunoglobulins, the method comprising: decapping a cysteine at amino acid position 80 (“Cys80”) in a light chain variable region of an immunoglobulin, wherein the immunoglobulin comprises a heavy chain variable region and the light chain variable region; and conjugating a thiol-reactive compound to the Cys80, wherein the thiol-reactive compound comprises a thiol-reactive group. Antigen-binding molecules and methods for generating the same, immunoglobulins as well as nucleic acid molecules encoding the immunoglobulins and host cells comprising the nucleic acid molecules, conjugated immunoglobulins, and light chain variable regions for use in a conjugated immunoglobulin are also provided.

Hidradenitis suppurativa can be treated by administering a pharmaceutical composition that includes a pharmaceutically acceptable carrier and a therapeutically effective amount of an agent that selectively binds IL-1α.

The present disclosure provides PD-1 binding proteins, particularly anti-PD-1 antibodies, or antigen-binding portions thereof, that specifically bind PD-1 and uses thereof. In one embodiment, the anti-PD-1 antibody comprises an antigen binding portion that binds a human PD-1 epitope or a non-human PD-1 epitope. Various aspects of the anti-PD-1 antibodies relate to antibody fragments, single-chain antibodies, pharmaceutical compositions, nucleic acids, recombinant expression vectors, host cells, and methods for preparing and using such anti-PD-1 antibodies. Methods for using the anti-PD-1 antibodies include in vitro and in vivo methods for binding PD-1, blocking interaction between PD-1 and PD-L1, detecting PD-1, and treating diseases associated with PD-L1 over-expression or PD-L1 detrimental expression.

Aspects of the disclosure relate to complexes comprising a muscle-targeting agent covalently linked to a molecular payload. In some embodiments, the muscle-targeting agent specifically binds to an internalizing cell surface receptor on muscle cells. In some embodiments, the molecular payload promotes the expression or activity of a functional dystrophin protein. In some embodiments, the molecular payload is an oligonucleotide, such as an antisense oligonucleotide, e.g., an oligonucleotide that causes exon skipping in a mRNA expressed from a mutant DMD allele.

The present invention provides broadly neutralizing antibodies against HIV, compositions comprising the same and methods of use thereof.

Provided herein are engineered IL2 polypeptides and fusion proteins thereof. Also provided are methods of modulating an immune response by administering an engineered IL2 polypeptide or a fusion protein thereof. The engineered IL2 polypeptides and fusion proteins thereof demonstrate increased binding to IL2Rβ, decreased binding to IL2Rα, or both.

Provided herein are methods for the treatment of cancers with antibody drug conjugates (ADC) that bind to 191P4D12 proteins.
