COMPOSITIONS AND METHODS FOR REGULATED SECRETION FROM NEUROENDOCRINE CELL LINES

摘要

The present invention provides compositions and methods of comprising engineered human neuroendocrine cell lines having a regulated secretory pathway. More particularly, the present invention provdes methods and compositions for engineering regulated secretion into cells. Certain aspects of the invention provide glycemic sensing mechanisms to a population of genetically engineered cells. In particular embodiments, the present invention provides compositions and methods of providing indirect glycemic sensing mechanisms to a population of genetically engineered cells. Specifically contemplated are methods and compositions for engineering indirect glucose sensing and glucose counter regulation capacity into cells. Methods of using these cells for minimizing hypoglycemia in diabetic therapy are also disclosed.
