The present invention provides antigen-binding proteins that specifically bind to an HLA-displayed human papillomavirus (HPV) peptide, and therapeutic and diagnostic methods of using those binding proteins.

Provided herein are HLA-PEPTIDE targets and multispecific antigen binding proteins that bind HLA-PEPTIDE targets. Provided herein is an isolated multispecific antigen binding protein (ABP), comprising: a first antigen binding domain (ABD) that specifically binds to a human leukocyte antigen (HLA)-PEPTIDE target; and an additional ABD that specifically binds an additional antigen, wherein the HLA-PEPTIDE target comprises an HLA-restricted peptide complexed with an HLA Class I molecule, wherein the HLA-restricted peptide is located in the peptide binding groove of an α1/α2 heterodimer portion of the HLA Class I molecule, and wherein the HLA-PEPTIDE target is selected from Table A, Table A1, or Table A2.

An objective of the present disclosure is to provide: anticancer agents having an immune cell-activating effect, a cytotoxic activity, or an antitumor activity, but having a low effect on non-tumor tissues such as normal tissues and having few side effects; combination therapies using those anticancer agents and other anticancer agents; and pharmaceutical combinations for use in those combination therapies.

Anticancer agents expected to be applied to various types of cancers, which have an immune cell-activating effect, a cytotoxic activity, or an antitumor activity while having a low effect on non-tumor tissues such as normal tissues and having few side effects by using as an active ingredient an anti-CD137 antigen-binding molecule of the present disclosure, the binding activity of which to CD137 changes depending on various substances (for example, low molecular weight compounds) in target tissues, are provided. Combination therapies using those anticancer agents and other anticancer agents, and pharmaceutical compositions for use in those combination therapies are also provided.

The inventors have found that the interaction between HP1 and INCENP can serve as an indicator for chromosome instability and established a method for evaluating chromosome instability of cancer cells. The evaluation system can be used for screening of anticancer agent with a new-concept of targeting chromosome instability of cancer cells. The inventors further prepared an antibody for specifically recognizing phosphorylation of serine at position 92 of HP1α, by which the action of Aurora B can be evaluated. The interaction between HP1 and INCENP can be readily evaluated by the antibody.

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

The present invention relates to anti-HLA-DQ2.5 antibodies and its use for the treatment of celiac disease. The present invention provides anti-HLA-DQ2.5 antibodies that have been modified. The anti-HLA-DQ2.5 antibodies of the invention have binding activity to complexes formed by HLA-DQ2.5 and a gluten peptide, but have substantially no binding activity to complexes formed by HLA-DQ2.5 and an irrelevant peptide. Furthermore, the antibodies of the invention are shown to have inhibitory effects on T cell activation by gluten peptides.

The present invention provides anti-HLA-DQ2.5 antibodies. The anti-HLA-DQ2.5 antibodies of the invention have binding activity to complexes formed by HLA-DQ2.5 and a gluten peptide, but have substantially no binding activity to complexes formed by HL A-DQ2.5 and an irrelevant peptide. Furthermore, it was found that the antibodies of the invention have inhibitory effects on T cell activation.

The present disclosure relates to proteins that bind to CD83 and uses thereof, for example, in therapy, prophylaxis, diagnosis, or prognosis.

Systems are described, based on a primary binding compound and a secondary binding compound used in combination with a support to detect a target in a sample. The systems includes at least one support structure, at least one small primary support portion containing at least one molecule covalently bound to a visual colloidal marker, a plurality of secondary support portions comprising secondary binding compounds that are covalently bound to the support portions and chemically active, at least one pH litmus indicator, at least one pH strip, a buffer for lateral flow on the porous membrane support that allows preservation and activity of binding compounds.

Disclosed herein are compositions and methods of treating a subject with cancer. The compositions and methods utilize immunoresponsive cells to effect killing of tumor cells.
