A problem to be solved by the present invention is to provide a novel agent that promotes chemotaxis of corneal epithelial cells. The problem is solved by an agent that promotes chemotaxis of corneal epithelial cells, comprising PACAP, PACAP derivatives, or a pharmaceutically acceptable salt thereof, as an active ingredient. The agent that promotes chemotaxis of corneal epithelial cells of the present invention preferably comprise 1 or more peptides belonging to a group PACAP, PACAP derivatives, or a pharmaceutically acceptable salt thereof. Concentration of PACAP, PACAP derivatives, or a pharmaceutically acceptable salt thereof is particularly preferably 1×10.sup.−13 mol/L or more and 1×10.sup.−7 mol/L or less. An agent that promotes chemotaxis of corneal epithelial cells of the present invention may be widely used as pharmaceuticals and the like for the improvement of symptoms of eye diseases such as dry eyes.

Compositions and methods for treating hyperinsulinemic hypoglycemia, such as hyperinsulinemic hypoglycemia after bariatric surgery, are provided. In some embodiments, an effective amount of the glucagon-like peptide-1 receptor antagonist exendin(9-39) is subcutaneously administered twice per day.

Treatment of hyperinsulinemic hypoglycemia comprises administration of an effective amount of a glucagon-like peptide-1 receptor antagonist (GLP1RA) alone or in combination with an amylinomimetic agent or any anti-gastric emptying agent. Patients suffering from hyperinsulinemic hypoglycemia after bariatric surgery experience particular benefit, as there is no current method effective for their treatment. Prevention or reduction of acute adverse effects of postprandial hypoglycemia, such as palpitations, tremor, weakness, sweating, confusion, fatigue, blurred vision, seizures, or loss of consciousness, and prevention of chronic adverse effects of hyperinsulinemic hypoglycemia, such as cognitive impairment, can be achieved by treatment with GLP1RA.

Described herein are thermally responsive polymer-therapeutic molecule conjugates comprising a therapeutic molecule conjugated to a thermally responsive polymer with an acrylate, methacrylate, acrylamide, and/or methacrylamide backbone and a plurality of oligoethylene glycol side chains.

The invention relates to novel polypeptide analogs of GLP-1 and exendin-4. The polypeptide, in a preferred embodiment, is insulinotropic and long-acting. Preferably, the polypeptide's insulinotropic effect is comparable to or exceeds the effect of an equimolar amount of GLP-1 or exendin-4. The invention also relates to a method of treating a subject with diabetes, comprising administering to the subject the polypeptide of the invention in an amount that has an insulinotropic effect. The invention also relates to methods of using GLP-1, exendin-4, and polypeptide analogs thereof for neuroprotective and neurotrophic effects.
