Capitalizing on this concept of somatostatin receptor positivity, somatostatin receptor scintigraphy has been developed to image tumors that arise from these cells. (medscape.com)

citation needed] Somatostatin is also produced by several other populations that project centrally, i.e., to other areas of the brain, and somatostatin receptors are expressed at many different sites in the brain. (wikipedia.org)
We observe that in a cell-intrinsic fashion, populations of mononuclear phagocytes and eosinophils express IL-22BP at the highest levels in comparison to other sources of T cells. (bvsalud.org)
Although class I tetramers identified large populations of virus-specific CD8 + cells, a different picture has emerged from the use of class II tetramers. (aai.org)

The six different genes, along with the five different somatostatin receptors, allow somatostatin to possess a large range of functions. (wikipedia.org)
RNA sequencing of single human islet cells reveals type 2 diabetes genes. (nature.com)
Linkage and comparative mapping studies indicate that the transferred chromosome segment contains a number of candidate genes for hypertension, including genes encoding a brain dopamine receptor and a renal epithelial potassium channel. (jci.org)

Humans have only one somatostatin gene, SST. (wikipedia.org)
Age-dependent pancreatic gene regulation reveals mechanisms governing human β cell function. (nature.com)
His calcium-sensing receptor ( CASR ) gene was sequenced and a rare inactivating variant was detected. (bioscientifica.com)
Magmas, a gene encoding for the mitochondrial import inner membrane translocase subunit, Tim16, protects different cell lines from the antitumoral effects of several pro-apoptotic stimuli (i.e. chemicals and chemotherapeutic agents). (endocrine-abstracts.org)
He also spearheaded an international effort to identify the first Mendelian germline predisposition gene in testicular germ cell tumors, CHEK2, with potentially immediate clinical and mechanistic implications. (the-asci.org)

Distinct insulins in humans and mice permit in vivo studies of human β-cell regulation after human islet transplantation in immunocompromised mice, whereas identical glucagon sequences prevent analogous in vivo measures of glucagon output from human α-cells. (nature.com)
Fig. 4: Human islet-derived glucagon corrects GKO-NSG α-cell hyperplasia. (nature.com)
The α-cell of the pancreatic islet modulates glucose homeostasis by secreting glucagon that acts primarily by driving hepatic glucose production. (diabetesjournals.org)
In islet β-cells, elevations in glucose increase the ATP-to-ADP ratio, resulting in the closure of ATP-sensitive K + (K ATP ) channels and causing action potential firing. (diabetesjournals.org)
Islet cell tumors may occur in children with multiple endocrine neoplasia type 1 (MEN1) syndrome. (cancer.gov)
The most common types of islet cell tumors are insulinomas and gastrinomas . (cancer.gov)
Other types of islet cell tumors are ACTHoma and VIPoma . (cancer.gov)

The gland is formed by multiple cell types, including basophilic, eosinophilic, and chromophobic cells (hematoxylin-eosin stain). (medscape.com)
During a meal, bile is secreted from the gland by smooth muscle contraction and reaches the duodenum portion of the small intestine by the common bile duct. (biologyonline.com)

Somatostatin has two active forms produced by the alternative cleavage of a single preproprotein: one consisting of 14 amino acids (shown in infobox to right), the other consisting of 28 amino acids. (wikipedia.org)

Epithelial cells remove excess hydrogen ions (H+) via membrane transport systems and have tight junctions, which prevent back diffusion of H+ ions. (merckmanuals.com)
Also, because NSAIDs are weak acids and are nonionized at gastric pH, they diffuse freely across the mucus barrier into gastric epithelial cells, where H+ ions are liberated, leading to cellular damage. (merckmanuals.com)
The surface of the stomach and opening of the gastric pits have a single layer of columnar epithelial cells, known as surface mucous cells or foveolar cells. (medicalnewstoday.com)
These micelles keep the insoluble products in soluble aggregates from which small amounts are released and absorbed by epithelial cells via diffusion. (biologyonline.com)
