Mechanisms controlling pancreatic islet cell function in insulin secretion

JE Campbell, CB Newgard - Nature reviews Molecular cell biology, 2021 - nature.com
Metabolic homeostasis in mammals is tightly regulated by the complementary actions of
insulin and glucagon. The secretion of these hormones from pancreatic β-cells and α-cells …

Pancreas regeneration

Q Zhou, DA Melton - Nature, 2018 - nature.com
The pancreas is made from two distinct components: the exocrine pancreas, a reservoir of
digestive enzymes, and the endocrine islets, the source of the vital metabolic hormone …

The physiological role of β-cell heterogeneity in pancreatic islet function

RKP Benninger, V Kravets - Nature Reviews Endocrinology, 2022 - nature.com
Endocrine cells within the pancreatic islets of Langerhans are heterogeneous in terms of
transcriptional profile, protein expression and the regulation of hormone release. Even …

A beta cell subset with enhanced insulin secretion and glucose metabolism is reduced in type 2 diabetes

A Rubio-Navarro, N Gómez-Banoy, L Stoll… - Nature cell …, 2023 - nature.com
The pancreatic islets are composed of discrete hormone-producing cells that orchestrate
systemic glucose homeostasis. Here we identify subsets of beta cells using a single-cell …

Leader β-cells coordinate Ca2+ dynamics across pancreatic islets in vivo

V Salem, LD Silva, K Suba, E Georgiadou… - Nature …, 2019 - nature.com

behaviour pertains to the situation in vivo, after innervation and during continuous perfusion …

Paracrine regulation of insulin secretion

MO Huising - Diabetologia, 2020 - Springer
Pancreatic beta cells are the only cell type in our body capable of producing and secreting
insulin to instruct the insulin-sensitive cells and tissues of our bodies to absorb nutrients after …

PDX1LOW MAFALOW β-cells contribute to islet function and insulin release

D Nasteska, NHF Fine, FB Ashford, F Cuozzo… - Nature …, 2021 - nature.com
Transcriptionally mature and immature β-cells co-exist within the adult islet. How such

[HTML][HTML] Heterogenous impairment of α cell function in type 2 diabetes is linked to cell maturation state

XQ Dai, J Camunas-Soler, LJB Briant, T Dos Santos… - Cell Metabolism, 2022 - cell.com
In diabetes, glucagon secretion from pancreatic α cells is dysregulated. The underlying
mechanisms, and whether dysfunction occurs uniformly among cells, remain unclear. We …
