Abstract: The present invention is directed to antibodies binding to aquaporin 4 (AQP4) and methods of using such antibodies to treat neuromyelitis optica (NMO) either as a monotherapy or in combination with standard NMO therapies such as immunosuppressives or plasmaphersis.

Abstract: Provided herein are methods and systems for screening a candidate agent to determine whether the candidate agent modulates an activity of cultured cells. Compositions for screening a candidate agent are also provided herein.

Abstract: Provided herein is a method of treating neuromyelitis optica (NMO) in an animal or human subject comprising administering to the subject a composition comprising a therapeutically effective amount of an Fc region modified anti-AQP4 antibody, thereby treating the NMO in the subject. In some embodiments, the Fc region modified anti-AQP4 antibody is an anti-AQP4 antibody deglycosylated at the amino acid position Asn297. In other embodiments, the Fc region modified anti-AQP4 antibody is an anti-AQP4 antibody F(ab?)2 fragment.

Abstract: Provided herein are small molecule inhibitors of pendrin. More specifically, the small molecules disclosed herein may be used to inhibit pendrin-mediated anion exchange. These small molecules may be used for treatment of diseases and disorders that are treatable by inhibiting pendrin, such as cystic fibrosis, rhinitis, chronic rhinosinusitis, exposure to an industrial toxin, certain viral infections, certain bacterial infections, and chronic obstructive pulmonary disease. The small molecules may further be used to potentiate a diuretic effect of a diuretic compound. The small molecules may additionally be used to treat hypertension or thyroid conditions.

Abstract: Provided herein are compounds that activate CFTR and methods for treating constipation, dry eye disorders, and other diseases and disorders.

Abstract: Provided herein are compounds that activate CFTR and methods for treating constipation, dry eye disorders or other diseases and disorders.

Abstract: Provided herein are inhibitors of transmembrane protein 16A (TMEM 16A), a Ca2+-activated CI? channel expressed widely in mammalian epithelia, as well as in vascular smooth muscle and some tumors and electrically excitable cells. TMEM16A inhibitors have potential utility for treatment or management of disorders of epithelial fluid and mucus secretion, hypertension, some cancers, pain, and other diseases.

Abstract: Provided herein are compounds that activate CFTR and methods for treating constipation, dry eye disorders, and other diseases and disorders.

Abstract: Provided herein are compounds that are urea transporter-A inhibitors that are useful for producing a strong diuretic response and may be used for treating refractory edema associated with cardiovascular, renal, and metabolic diseases, disorders, and conditions.

Abstract: Provided herein are methods for identifying compounds that are inhibitors of a calcium-activated chloride channel. Aminothiophene and aminothiazole compounds, and compositions comprising these compounds, described herein that inhibit efflux of chloride through a calcium-activated chloride channel are useful for treating diseases, disorders, and sequelae of diseases, disorders, and conditions that are associated with aberrantly increased chloride and fluid secretion, for example, secretory diarrhea.

Abstract: Provided herein are small molecule activators of calcium-activated chloride channels. These small molecules may be used for treatment of diseases and disorders that are treatable by activating calcium-activated chloride channels, such as cystic fibrosis, disorders related to salivary gland dysfunction (for example, Sjogren's syndrome and dysfunction following radiation injury), dry eye syndrome, and intestinal hypomotility.

Abstract: Provided herein are compounds that are urea transporter-A inhibitors that are useful for producing a strong diuretic response and may be used for treating refractory edema associated with cardiovascular, renal, and metabolic diseases, disorders, and conditions.

Abstract: Provided herein are methods for identifying and characterizing agents that alter the volume of a cell. Methods are provided for rapid screening and identification of an agent that alters the capability of a small, neutrally charged solute transporter to transport the solute across a cell membrane. The methods described herein may be used to identify and characterize inhibitors of urea transporters, to identify and characterize inhibitors of aquaporins, and to identify and characterize inhibitors of other small, neutrally charged solutes such as glucose.

Abstract: Provided herein are small molecule triazolothienopyrimidine compounds that inhibit urea transport activity of solute transporters, particularly the UT-B transporter. The compounds described herein are useful for increasing solute clearance in states of fluid overload and for treating refractory edema associated with cardiovascular, renal, and metabolic diseases, disorders, and conditions.
