Disclosed is a method for refolding a protein or peptide that does not contain essential disulfides and that contains at least one free cysteine residue. Also disclosed are polymer IFN- conjugates that have been created by the chemical coupling of polymers such as polyethylene glycol moieties to IFN-, particularly via a free cysteine in the protein. Also disclosed are analogs of bioactive peptides that may be used to create longer acting versions of the peptides, including analogs of glucagon, glucagon-like peptide-1 (GLP-1), GLP-2, Gastric inhibitory peptide (GIP), PYY, exendin, ghrelin, gastrin, amylin, and oxyntomodulin.

The present invention relates to a secretin receptor modulator for use in the prevention and/or treatment of a disease or disorder of energy homeostasis, wherein (a) said secretin receptor modulator is a secretin receptor agonist and said disease or disorder is obesity, dyslipidemia, diabetes, insulin resistance, hyperglycemia, high blood pressure or metabolic syndrome, whereby the secretin receptor agonist increases non-shivering thermogenesis in brown adipocytes and/or increases the expression of uncoupling protein 1 (UCP1) in brown adipocytes and/or decreases food intake in a UCP1-dependent manner resulting in the prevention and/or treatment of said disease or disorder; or (b) said secretin receptor modulator is a secretin receptor antagonist and said disease or disorder is cachexia. The invention further relates to a method of increasing non-shivering thermogenesis in brown adipocytes and/or increasing the expression of uncoupling protein 1 (UCP1) in brown adipocytes, to a method of decreasing non-shivering thermogenesis in brown adipocytes, to a method of identifying a secretin receptor agonist capable of increasing non-shivering thermogenesis in brown adipocytes and/or increasing the expression of uncoupling protein 1 (UCP1) in brown adipocytes, to a method of identifying a secretin receptor antagonist capable of decreasing non-shivering thermogenesis in brown adipocytes, to the use of the secretin receptor for screening (a) for secretin receptor agonists that increase non-shivering thermogenesis in brown adipocytes and/or increase the expression of uncoupling protein 1 (UCP1) in brown adipocytes and/or decrease food intake in a UCP1-dependent manner; and/or (b) for secretin receptor antagonists that decrease non-shivering thermogenesis in brown adipocytes, and to the use of a secretin receptor agonist to activate non-shivering thermogenesis in brown adipocytes and/or to increase the expression of uncoupling protein 1 (UCP1) in brown adipocytes and/or to decrease food intake in a UCP1-dependent manner for reducing body weight for cosmetic purposes as well as to the use of a secretin receptor antagonist to decrease thermogenesis in brown adipocytes for increasing body weight for cosmetic purposes.

Disclosed is a method of modulating the Sct/SR axis in a mammalian subject in need thereof, including in a subject suffering from a liver disease, such as but not limited to, Early Stage PBC, Primary Sclerosing Cholangitis, Primary Biliary Cholangitis, Biliary Atresia, NASH, NAFLD, or Alcohol induced liver injury. A method of treating Late Stage PBC in a mammalian subject in need thereof is also disclosed; further disclosed is a method of ameliorating PBC-induced biliary damage in a mammalian subject in need thereof. Pharmaceutical compositions for modulating the Sct/SR axis, comprising a SR antagonist or a SR agonist, and a pharmaceutically acceptable carrier or excipient are also disclosed.

The present invention relates to the field of biopharmaceuticals, and in particular to a protein, a protein conjugate, a pharmaceutical composition and its use for treating diabetes. The fusion protein of the present invention is obtained by linking two polypeptides, wherein one polypeptide is an interleukin-1 receptor antagonistic protein or an analogue thereof, and another polypeptide is GLP-1 receptor binding polypeptide or an analogue thereof, or an insulin receptor binding polypeptide or an analogue thereof, or a GIP receptor binding polypeptide or an analogue thereof. The fusion proteins of the present invention and conjugates thereof have a significant efficacy in treating diabetes, and can be used in a lower dose, resulting in marked reduction in side effects.
