Mechanosensation isn't just at the cell surface. In gut smooth muscle, we found that Piezo1 is mostly intracellular, <40 nm from RyR and BK channels. Activating it hyperpolarizes cells and weakens contraction- like a molecular brake. Stay tuned for more to come! J Physiol: doi.org/10.1113/JP29...

Pleased to report we made the cover of the upcoming issue of Diabetologia for our most recent paper!! The effort was led by Ryan Hart (@ryanhart13.bsky.social). Description in the ALT text, full open acces link here: rdcu.be/fptyS
The cover image of the September issue of the scientific journal 'Diabetologia'.

The cover picture shows a high-resolution image of a live murine pancreatic islet expressing the calcium indicator GCaMP6s in every islet cell. Alpha and beta cells are pseudocoloured in hot pink and grey blue, respectively. Select single cell calcium responses to a succession of stimuli, including glucose, amino acids, somatostatin, epinephrine and potassium chloride, are highlighted. The extent and mechanisms of somatostatin inhibition of beta and alpha cell calcium and cAMP signalling have not previously been compared directly in real time. In the September issue of Diabetologia, Hart et al report that during nutrient stimulation, somatostatin inhibits insulin secretion indirectly by restraining alpha cell calcium and cAMP downstream of somatostatin receptor 2; this prevents glucagon from stimulating beta cells.
