How does P2RX7 purinergic signaling mechanistically regulate pancreatic β-cell function and insulin sensitivity?

OPEN

The study identifies P2RX7 polymorphisms associated with glucose homeostasis traits but doesn't explain the molecular mechanisms by which purinergic signaling controls β-cell function. Understanding this pathway could reveal new therapeutic targets for diabetes. Gap type: unexplained_observation Source paper: Variation in glucose homeostasis traits associated with P2RX7 polymorphisms in mice and humans. (2015, J Clin Endocrinol Metab, PMID:25719930)
