Hyperactive Somatostatin Interneurons Contribute to Excitotoxicity in Neurodegenerative Disorders

open access: yesNature Neuroscience, 2016
Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are overlapping neurodegenerative disorders whose pathogenesis remains largely unknown.

ACSS2/AATF Drives Soluble FasL‐Mediated CD8+ T Cell Apoptosis in Pancreatic Neuroendocrine Tumors

open access: yesAdvanced Science, EarlyView.
This study unveils that ACSS2‐driven acetate metabolism fuels histone pan‐acetylation in pancreatic neuroendocrine tumors (PNETs), remodeling the epigenetic landscape. The ACSS2/AATF axis transcriptionally activates soluble FasL (sFasL), which engages Fas receptors on infiltrating CD8+ T cells to trigger caspase‐8/3‐mediated apoptosis.

Towards a Radio-guided Surgery with $\beta^{-}$ Decays: Uptake of a somatostatin analogue (DOTATOC) in Meningioma and High Grade Glioma

open access: yes, 2014
A novel radio guided surgery (RGS) technique for cerebral tumors using $\beta^{-}$ radiation is being developed. Checking the availability of a radio-tracer that can deliver a $\beta^{-}$ emitter to the tumor is a fundamental step in the deployment of ...

Substance P-expressing excitatory interneurons in the mouse superficial dorsal horn provide a propriospinal input to the lateral spinal nucleus [PDF]

open access: yes, 2018
The superficial dorsal horn (laminae I and II) of the spinal cord contains numerous excitatory and inhibitory interneurons, and recent studies have shown that each of these groups can be divided into several neurochemically distinct populations. Although

Urocortin3 mediates somatostatin-dependent negative feedback control of insulin secretion

open access: yesNature Network Boston, 2015
The peptide hormone urocortin3 (Ucn3) is abundantly expressed by mature beta cells, yet its physiological role is unknown. Here we demonstrate that Ucn3 is stored and co-released with insulin and potentiates glucose-stimulated somatostatin secretion via ...

Deficiency of Leucine‐Rich Repeat Containing G Protein‐Coupled Receptor 4 in Pancreas Reduces β Cell Mass

open access: yesAdvanced Science, EarlyView.
In islet β cells, LGR4 binds with Rspondin to activate the Wnt‐β‐catenin‐Ccnd1 axis, leading to a subsequent increase in cell proliferation. On the other hand, LGR4 also binds with RANKL, thus suppressing the phosphorylation of p44/p42 MAPK and p65 NF‐κB and subsequent cell apoptosis.

The role of serotonin inhibition within the treatment of carcinoid syndrome

open access: yesEndocrine Oncology, 2023
Carcinoid syndrome is the most frequent hormonal complication associated with neuroendocrine neoplasms. It was first reported in 1954, and the classical symptoms are diarrhoea, flushing and abdominal pain.

Somatostatin and Somatostatin-Containing Neurons in Shaping Neuronal Activity and Plasticity

open access: yesFront. Neural Circuits, 2016
Since its discovery over four decades ago, somatostatin (SOM) receives growing scientific and clinical interest. Being localized in the nervous system in a subset of interneurons somatostatin acts as a neurotransmitter or neuromodulator and its role in ...

Indications for Surgical Resection in Patients With Neuroendocrine Tumor Liver Metastases: An Intensive Surgical Experience of a High‐Volume Center

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
In patients with NELM, those with < 8 liver metastases and G1/2 tumors are the favorable candidates for liver resection. The important point of this study is that the patients who do not meet the above criteria should be considered for multidisciplinary treatment because of their extremely shorter recurrence‐free period.

Gastroesophageal tube of the Iguana iguana (Iguanidae): histological description, histochemical and immunohistochemical analysis of 5-HT and SS cells

open access: yesBrazilian Journal of Biology, 2021
The work aims were to describe the histological and histochemical structure of the gastroesophageal tube of Iguana iguana and verify the occurrence and distribution of immunoreactive serotonin (5-HT) and somatostatin (SS) cells.
