The present invention generally relates to antibodies, antigen-binding fragments thereof, polypeptides, and immunoconjugates that bind to CD123 antigen (the α chain of the interleukine 3 receptor, or IL-3Rα). The present invention also relates to methods of using such CD123-binding molecules for diagnosing and treating diseases, such as B-cell malignancies.

This invention relates to the use of a CD24 protein for treating leptin-deficient conditions, such as lipodystrophy, by increasing the level of circulating leptin.

Anti-CD45RC antibodies, for use in the treatment of monogenic diseases caused by genes not associated with immune function but whose deficiency is associated with inflammation and/or immune reactions (such as genes deficient in Duchenne muscular dystrophy (DMD), cystic fibrosis, lysosomal diseases and al-anti-trypsin deficiency); or caused by genes involved in the immune system and whose deficiency generates inflammation and/or autoimmune reactions (such as genes deficient in T-cell primary immunodeficiencies such as IPEX (immunodysregulation polyendocrinopathy enteropathy X-linked syndrome), APECED (autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy), B cell primary immunodeficiencies, Muckle-Wells syndrome, mixed autoinflammatory and autoimmune syndrome, NLRP12-associated hereditary periodic fever syndrome, and tumor necrosis factor receptor 1 associated periodic syndrome).

The invention relates to a pharmaceutical formulation comprising a mixture of a non-reducing sugar, a recombinant humanized anti-Her2 monoclonal antibody-MMAE conjugate, and a surfactant. The pharmaceutical formulation has characteristics of reduced particulate matter, reduced aggregates, improved stability of the conjugate, improved appearance of the lyophilized powders and the like.

The disclosure relates to binding molecules that bind specifically to prostate specific membrane antigen (PSMA), in particular, single human variable heavy chain domain antibodies and related methods for treatment of cancer.

Disclosed herein are anti-Seizure Related 6 Homolog Like 2 (SEZ6L2) antibodies and antibody dmg conjugates (ADCs), including compositions and methods of using said antibodies and ADCs.

In certain embodiments internalizing anti-CD146 antibodies and conjugates thereof are provided. It was discovered that anti-CD146 antibodies are capable of targeting both epithelioid and sarcamatous subtypes of mesothelioma cells. In certain embodiments methods of detecting and/or treating mesothelioma are provided.

A subject of the present invention is to provide an anti AQP3 antibody specifically recognizing the extracellular domain of aquaporin 3 (AQP3), which is one type of a water channel protein. By selecting a monoclonal antibody which specifically binds to an oligopeptide included in loop C as one of the extracellular domains of AQP3, an anti AQP3 antibody that is desired in the present invention is provided. An anti AQP3 monoclonal antibody of the present invention can directly bind, from the outside of a cell, to AQP3 present in a cell membrane. Furthermore, as an anti AQP3 monoclonal antibody of the present invention can have an inhibitory activity, the function of permeating a low molecular weight molecule or the like, which is carried by AQP3, can be suppressed.

The present invention relates to the fields of treating autoimmune diseases and molecular immunology, and specifically, to an anti-IL-17A antibody, a pharmaceutical composition thereof, and use thereof. More specifically, the present invention relates to a monoclonal antibody or an antigen binding fragment thereof, wherein a heavy chain variable region of the monoclonal antibody comprises: HCDR1-HCDR3 with amino acid sequences set forth in SEQ ID NOs: 31-33 respectively, or HCDR1-HCDR3 with amino acid sequences set forth in SEQ ID NOs: 37-39 respectively, and a light chain variable region of the monoclonal antibody comprises: LCDR1-LCDR3 with amino acid sequences set forth in SEQ ID NOs: 34-36 respectively, or LCDR1-LCDR3 with amino acid sequences set forth in SEQ ID NOs: 40-42 respectively. Monoclonal antibodies of the present invention can specifically bind to IL-17A, specifically antagonize the binding of IL-17A to a ligand thereof, and inhibit activation of fibroblasts by IL-17A.
