INHIBITORY INTERNEURON TREATMENT METHODS, USES, AND COMPOSITIONS FOR DIABETES
Disclosed herein are compositions, methods of treatment, and uses of inhibitory interneuron precursors, derived from the brain's medial ganglionic eminence, or differentiated from iPSC or ESCs, for the treatment of pre-diabetes or diabetes. In some embodiments, compositions including inhibitory interneuron precursors are transplanted into the arcuate nucleus of the hypothalamus region of the brain, to treat, for example, diabetes, such as, type-2 diabetes. In further embodiments, inhibitory interneuron precursors are used in the manufacture of a medicament for the treatment of diabetes, for example, type-2 diabetes.
1 . A method for the treatment of hyperglycemia in a subject in need thereof, comprising:
administering an effective amount of mammalian medial ganglionic eminence (MGE) precursor cells to one or more of the arcuate nucleus of the hypothalamus region of the brain of the subject, the mediobasal hypothalamus region of the brain of the subject, and the ventromedial hypothalamus region of the brain of the subject, wherein the mammalian MGE precursor cells form interneurons that functionally integrate with endogenous neurons such that an improvement in the symptoms of hyperglycemia in the subject is achieved.
2 . The method of claim 1 , wherein the mammalian MGE precursor cells are administered by injection.
3 . The method of claim 1 , wherein the mammalian MGE precursor cells are administered through transplantation with a catheter or needle.
4 . The method of claim 1 , wherein between about 20 nanoliters to 50 microliters of a suspension comprising the mammalian MGE precursor cells is administered.
5 . The method of claim 1 , wherein the mammalian MGE precursor cells are embryonic MGE precursor cells.
6 . The method of claim 1 , wherein the mammalian MGE precursor cells are cultured MGE precursor cells.
7 . The method of claim 1 wherein the mammal is a human.
8 . The method of claim 1 , wherein administration is to the arcuate nucleus of the hypothalamus region of the brain.
