Co‐activation of Selective Nicotinic Acetylcholine Receptor Subtypes Is Required for Neuroprotection against Alzheimer's Disease

Advanced Science, EarlyView.
ABSTRACT Beta‐amyloid peptide (Aβ)‐induced suppression of hippocampal GABAergic interneuron activity drives hyperexcitability, amyloid pathology, and cognitive impairment in Alzheimer's disease (AD), suggesting that enhancing hippocampal inhibition may be protective.

Agonists, Antagonists and Receptors of Somatostatin: Pathophysiological and Therapeutical Implications in Neoplasias

Current Issues in Molecular Biology
Somatostatin is a peptide that plays a variety of roles such as neurotransmitter and endocrine regulator; its actions as a cell regulator in various tissues of the human body are represented mainly by inhibitory effects, and it shows potent activity ...

Oral Actinomyces Species Exposure is Associated with Anxiety‐Like Behavior, Mitochondrial Remodeling, and Altered GABAergic Pathways

Advanced Science, EarlyView.
Oral exposure to cannabis‐associated Actinomyces species, particularly A. meyeri, is associated with anxiety‐like behavior in mice in the absence of detectable bacterial translocation or overt systemic inflammation. These findings support a potential oral‐brain metabolic axis involving candidate metabolites such as arginine and argininosuccinate ...

Somatostatin and opioid receptors do not regulate proliferation or apoptosis of the human multiple myeloma U266 cells

Journal of Experimental & Clinical Cancer Research, 2009
Background opioid and somatostatin receptors (SSTRs) that can assemble as heterodimer were individually reported to modulate malignant cell proliferation and to favour apoptosis.

North American Delphi Consensus Study on Sinonasal Malignancy Survivorship Care

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Survival for patients with sinonasal cancers has improved over the past decades, but there are no dedicated survivorship guidelines for this cohort. Objective To understand experts’ priorities and perspectives on key survivorship tenets (surveillance, second tumor screening, toxicity, and symptom management).

Lutathera^®: The First FDA- and EMA-Approved Radiopharmaceutical for Peptide Receptor Radionuclide Therapy

Pharmaceuticals, 2019
As the first radiopharmaceutical for Peptide Receptor Radionuclide Therapy (PRRT), Lutathera® was approved by the EMA in 2017 and the FDA in 2018 for the treatment of somatostatin receptor (SSTR) positive gastroenteropancreatic neuroendocrine tumors.

Early Versus Late Recurrence in Olfactory Neuroblastoma: A Multi‐Institutional Analysis of Predictive Risk Factors

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory neuroblastoma (ONB) exhibits variable recurrence patterns, with significant late recurrences occurring years after treatment. We investigated cutoff periods to define late recurrence and identified predictors that distinguish patients at risk of late recurrence from those considered cured.

Pulmonary large cell neuroendocrine carcinoma (LCNEC) with confirmed liver metastases negative on 18F-FDG and 68Ga-DOTATATE PET

Radiology Case Reports, 2020
Lung neuroendocrine neoplasms (NENs) encompass the low-, intermediate-, and high-grade entities. Differentiated NENs overexpress somatostatin receptors, which are targeted by 68Ga-DOTA-conjugated peptides in molecular imaging with positron emission ...

Somatostatin/somatostatin receptor signalling: Phosphotyrosine phosphatases [PDF]

Molecular and Cellular Endocrinology, 2008
Activation of phosphotyrosine phosphatases (PTPs) by somatostatin receptor (SSTR) represents one of the main intracellular mechanisms involved in the antiproliferative effect of somatostatin (SST) and analogues. Since their molecular cloning, the role of PTPs is emerging as a major regulator of different cell functions including cell proliferation ...

T Cell‐Mediated Targeting of Interneurons in Mice Shapes Hippocampal Remodeling and Epilepsy

Annals of Neurology, EarlyView.
Objective Autoimmune encephalitis (AE) is associated with autoantibodies targeting distinct neuronal populations. In AE, antibodies against glutamate decarboxylase 65 (GAD65), expressed in GABAergic interneurons, are frequently detected. In GAD65‐AE, hippocampal biopsies often show infiltrates of CD8+ cytotoxic T cells (CTLs), suggesting a prominent T ...
