    Another one of these details can be noted in insulins secretory granules, or container like buds, that store insulin within a cell. In PP cells, the size of the insulin granules are smaller and spherical and similar to those in alpha cells. This is noted in human PP cells, but different animals have been shown to have different sized granules ...

    Immunohistochemistry for pancreatic polypeptide in a mouse pancreas, 200×. Pancreatic polypeptide (PP) is a polypeptide secreted by PP cells in the endocrine pancreas.It is a hormone and it regulates pancreatic secretion activities, and also impacts liver glycogen storage and gastrointestinal secretion.

It also affects hepatic glycogen levels and gastrointestinal ...

    They give rise to both the endocrine and exocrine cells. Exocrine cells constitute the acinar cells and the ductal cells. The endocrine cells constitute the beta cells which make insulin, alpha cells which secrete glucagon, delta cells which secrete somatostatin and the PP-cells which secrete pancreatic polypeptide. [3]

    One year before, still as an undergraduate, he analysed epidermal skin cells as part of an open competition organised by Berlin University. The branched skin cells resembling neuron, described in his paper entitled “On the nerves of the human skin,” remained an enigma for over a century before their immunological function and significance ...

    en.wikipedia.org/wiki/Endocrine_system

    Pancreas contain nearly 1 to 2 million islets of Langerhans (a tissue which consists cells that secrete hormones) and acini. Acini secretes digestive enzymes. [9] Alpha cells. The alpha cells of the pancreas secrete hormones to maintain homeostatic blood sugar. Insulin is produced and excreted to lower blood sugar to normal levels.

  8. Beta cell - Wikipedia

    [2] [9] The beta cells can still secrete insulin but the body has developed a resistance and its response to insulin has declined. [4] It is believed to be due to the decline of specific receptors on the surface of the liver , adipose , and muscle cells which lose their ability to respond to insulin that circulates in the blood.

  9. Proinsulin - Wikipedia

    en.wikipedia.org/wiki/Proinsulin

    Proinsulin is the prohormone precursor to insulin made in the beta cells of the Pancreatic Islets, specialized regions of the pancreas. In humans, proinsulin is encoded by the INS gene . [ 1 ] [ 2 ] The pancreatic islets only secrete between 1% and 3% of proinsulin intact. [ 3 ]
