NettetIntroduction. Type 2 diabetes (T2D) is characterized by hyperglycemia in the context of insulin resistance and β-cell dysfunction. 1 Over time, islet β-cell function compensates for the insulin resistance existing in peripheral tissues, resulting in defects in insulin secretion that impair the regulation of blood glucose levels. 1–3 Moreover, postmortem … NettetThe purpose of this study was to investigate whether FO derived from Sargassum hemiphyllum ameliorates pancreatic β-cell damage and impaired insulin synthesis …

The primary function of a beta cell is to produce and release insulin and amylin. Both are hormones which reduce blood glucose levels by different mechanisms. Beta cells can respond quickly to spikes in blood glucose concentrations by secreting some of their stored insulin and amylin while simultaneously producing more. Primary cilia on beta cells regulate their function and energy metabolism…
