procedureIncreased blood glucose levels stimulate beta cells in the pancreas to produce insulin.

claimBasal insulin concentration oscillates in the blood following a meal due to the synchronization of insulin release among pancreatic beta cells.

procedureThe negative feedback control of blood sugar proceeds as follows: (1) the small intestine absorbs glucose from digested food after a meal, causing blood glucose levels to rise; (2) increased blood glucose levels stimulate beta cells in the pancreas to produce insulin; (3) insulin triggers liver, muscle, and fat tissue cells to absorb and store glucose; (4) blood glucose levels fall as glucose is absorbed; (5) once glucose levels drop below a threshold, the stimulus for insulin release ceases, and beta cells stop releasing insulin.

claimType 1 Diabetes occurs when pancreatic beta cells are destroyed by an immune-mediated process, resulting in a complete lack of insulin.

procedureOnce blood glucose levels drop below a threshold, the stimulus for insulin release is removed, and pancreatic beta cells stop releasing insulin.

referenceAndrographolide and analogous diterpenoids safeguard pancreatic beta-cells from death and facilitate islet cell regeneration, preserving insulin production capability and inhibiting diabetes progression, according to Chattopadhyay et al. (2025).

claimSulfur-containing compounds from garlic, specifically allicin and S-methylcysteine sulfoxide, promote insulin secretion from pancreatic beta-cells and augment glucose-induced insulin release.

claimGarlic-derived compounds safeguard beta-cells from glucotoxicity, preventing a reduction in insulin secretory capacity through antioxidant mechanisms and anti-apoptotic effects.

claimThe physiological system does not necessarily maintain a fixed glucose setpoint but undergoes adaptation to chronic stress, where higher glycemia is necessary to continuously trigger beta-cells to ensure a greater insulin secretory response to the next glucose uptake, as noted by Stumvoll et al. (2003).

claimIn type 1 diabetes, pancreatic alpha cells paradoxically secrete glucagon in response to hyperglycemia, a process that occurs even before the destruction of pancreatic beta cells, which normally produce insulin to inhibit glucagon secretion.

claimPancreatic beta cells release insulin into the bloodstream when blood glucose levels rise above the normal range, signaling cells to absorb excess glucose until levels return to normal.

referenceFang J, Chen Z, Lai X, Yin W, Guo Y, Zhang W et al. reported in Bioorganic Chemistry (2022) that mesenchymal stem cell-derived HIF-1α-overexpressed extracellular vesicles ameliorate hypoxia-induced pancreatic β cell apoptosis and senescence through activating YTHDF1-mediated protective autophagy.
