Provided are anti-PD-L1 antibodies or fragments thereof. The antibodies or fragments thereof specifically bind to the immunoglobulin C domain of the PD-L1 protein. In various example, the antibodies or fragments thereof include a VH CDR1 of SEQ ID NO: 1, a VH CDR2 of SEQ ID NO: 2, a VH CDR3 of SEQ ID NO: 3, a VL CDR1 of SEQ ID NO: 4, a VL CDR2 of SEQ ID NO: 5, and a VL CDR3 of SEQ ID NO: 6, or variants of each thereof. Methods of using the antibodies or fragments thereof for treating and diagnosing diseases such as cancer and infectious diseases are also provided.

The present invention relates to an antibody specifically binding to human growth arrest specific 6 (hGas6). Specifically, the present invention relates to a monoclonal antibody or an antibody fragment thereof which binds to at least one of amino acid residues at positions 314, 315, and 316 of human Gas6, a nucleic acid comprising a nucleotide sequence encoding the antibody or the antibody fragment, a transformed cell comprising a vector comprising the nucleic acid, a method for producing the antibody or the antibody fragment, a reagent for detection or assay of Gas6, comprising the antibody or the antibody fragment, a therapeutic agent or a diagnostic agent for a Gas6-related disease, comprising the antibody or the antibody fragment as an active ingredient, and use of the antibody or the antibody fragment for the production of a therapeutic agent or a diagnostic agent for a Gas6-related disease.

The present disclosure, among other things, provides low-viscosity, high concentration therapeutic protein agent formulations.

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

The present invention relates to antibodies and antigen binding fragments thereof, which bind to a complex of GARP and TGF-?1, particularly a complex of human GARP and human TGF-?1. These antibodies and antigen binding fragments exhibit a combination of advantageous properties including high affinity antigen binding and the ability to inhibit the release of active TGF-? from regulatory T cells. The antibodies and antigen binding fragments of the present invention are relatively resistant to deamidation, isomerization and oxidation, such that they display improved stability.

The present invention pertains to antigen recognizing constructs against COL6A3 antigens. The invention in particular provides novel T cell receptor (TCR) based molecules which are selective and specific for the tumor expressed antigen COL6A3. The TCR of the invention, and COL6A3 antigen binding fragments derived therefrom, are of use for the diagnosis, treatment and prevention of COL6A3 expressing cancerous diseases. Further provided are nucleic acids encoding the antigen recognizing constructs of the invention, vectors comprising these nucleic acids, recombinant cells expressing the antigen recognizing constructs and pharmaceutical compositions comprising the compounds of the invention.

Methods to create chemically-induced dimerizing (CID) protein systems and uses thereof are described. The methods utilize antibody binding domain dimerizing proteins. The created systems can be used to regulate cellular events such as gene expression, receptor signaling and cell death to effectuate a variety of clinically relevant treatment outcomes.

The present invention relates to antibody-based molecules (including single domain antibody fragment, scFv molecules, antibodies, antibody fragments, diabodies, and the epitope-binding domains thereof) that are capable of immunospecifically and selectively binding to the .sup.{p}Ser404 Epitope of Tau. Such antibody-based molecules are useful to detect pathological Tau protein conformer if present in a biological sample, especially in conjunction with the diagnosis and/or treatment of Alzheimer's disease or other tauopathy, and thus provide a diagnostic for Alzheimer's disease and other Tau pathologies. The antibody -based molecules of the present invention have particular utility as diagnostic markers for, Alzheimer's disease and related tauopathies and as pharmaceutical compositions for the treatment of such conditions.

Agents that specifically bind TIGIT are disclosed. The TIGIT-binding agents may include polypeptides, antibodies, and/or bispecific agents. Also disclosed are methods of using the agents for enhancing the immune response and/or treatment of diseases such as cancer.

Phycoerythrin (PE) and peptide:MHCII (p:MHCII) reactive monoclonal antibodies; methods to generate monoclonal antibodies including, for example, peptide:MHC (p:MHC) reactive monoclonal antibodies; compositions including monoclonal antibodies; and uses thereof.
