Abstract: This disclosure provides the use of recombinant IgG Fc multimers for the treatment of neuromyelitis optica (NMO), and methods of treating NMO by administering such multimers.

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 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 anli-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 anii-AQP4 antibody F(ab?)2 fragment.

Abstract: Provided herein are pyrimido-pyrrolo-quinoxalinedione (PPQ) compounds, and compositions comprising these compounds, that inhibit cystic fibrosis transmembrane conductance regulator (CFTR) mediated ion transport and that are useful for treating diseases and disorders associated with aberrantly increased CFTR chloride channel activity. The compounds, and compositions comprising the compounds, described herein are useful for treating diseases, disorders, and sequelae of diseases, disorders, and conditions that are associated with aberrantly increased CFTR activity, for example, polycystic kidney disease. The compounds may be used for inhibiting expansion or preventing formation of cysts in persons who have polycystic kidney disease.

Abstract: Disclosed herein are methods of treating diseases including gastrointestinal disorders, such as secretory diarrheas, with the proanthocyanidin oligomer, crofelemer. Also disclosed is the anti-secretory effect of crofelemer on Calcium-activated chloride channels (CaCC) and Cystic fibrosis transmembrane conductance regulator (CFTR).
