is·lets of Lan·ger·hans

(lahng'ĕr-hahnz),
cellular masses consisting of several to several hundred cells lying in the interstitial tissue of the pancreas; they are composed of five different cell types that make up the endocrine portion of the pancreas and are the sources of insulin, glucagon, somatostatin, pancreatic polypeptide, and gastrin.

Regarding the study of mechanisms, an in vivo study demonstrated that methimazole-induced hypothyroidism promotes immune cell infiltration into pancreatic islets of female rabbits, which could be inducing pancreatitis and insulitis [79].
In the pancreatic endocrine portion, ghrelin-ip cells were located among the pancreatic islet cells, and and the distribution of ghrelin-ip cells was observed mostly at the periphery of the islet, a few ghrelin-ip cells were found in the central portion of pancreatic islets.
Accordingly, we recently demonstrated that HyO pancreatic islets present a higher [beta]-cell number per islet, indicating that compensatory morphofunction alterations in the HyO pancreas are accompanied by enhanced islet-cell replication, induced by vagal hypertonia, since truncal vagotomy in HyO rats normalized [beta]-cell amount per islet (17).
Also, our previous study on rat model of diabetes has shown that STZ markedly cause reduction in [beta]-cells mass and pancreatic islets in adult rats (Golalipour et al., 2010).
