Transient receptor potential vanilloid 1 (TRPV1) channels expressed in sensory nerves may regulate vascular tone and cardiovascular function via their anti-inflammatory effects by releasing neuropeptide calcitonin gene-related peptide (CGRP). Inflammation plays a role in the progression of cardiac hypertrophy and TRPV1 activation may be key to cardiac inflammatory processes. The aim of this study was to test the hypothesis that TRPV1 modulates inflammatory processes to protect the heart from pressure overload-induced hypertrophy and inflammatory responses...

Background: Clinical studies have shown that applying pulsed radiofrequency (PRF) to the neural stem could relieve neuropathic pain (NP), albeit through an unclear analgesic mechanism. And animal experiments have indicated that calcitonin gene-related peptide (CGRP) expressed in the dorsal root ganglion (DRG) is involved in generating and maintaining NP. In this case, it is uncertain whether PRF plays an analgesic role by affecting CGRP expression in DRG. Methods: Rats were randomly divided into four groups: Groups A, B, C, and D...

BACKGROUND AND PURPOSE: Capsaicin-mediated modulation on taste nerve responses is thought to be produced indirectly by actions of neuropeptides, e.g., calcitonin gene-related peptide (CGRP) and substance P (SP), onto taste cells implying playing a role in taste sensitivity. During processing gustatory information in taste buds, CGRP shapes peripheral taste signals via serotonergic signaling. The underlying assumption has been that SP exerts its effects on taste transmitter secretion in taste buds of mice...

Small cell variant of medullary thyroid carcinoma (MTC) is a rare variant. In the past, primary thyroid lymphomas were thought to be small cell MTC (SCMTC). However, with the advent of immunohistochemistry, it was realized that SCMTC is rare. Our patient presented with neck mass for 1 year with an outside laboratory report of neoplastic lesion. His serum calcitonin levels were normal, but serum carcinoembryonic antigen (CEA) levels were high. He underwent total thyroidectomy and was diagnosed to have small cell variant of MTC...

Persistent inflammation is well known to promote the progression of arthropathy. mesenchymal stem cells (MSCs) have been shown to possess anti-inflammatory properties and tissue differentiation potency. Although the experience so far with the intraarticular administration of mesenchymal stem cell (MSC) to induce cartilage regeneration has been disappointing, MSC implantation is now being attempted using various surgical techniques. Meanwhile, prevention of osteoarthritis (OA) progression and pain control remain important components of the treatment of early-stage OA...

Solid cell nests (SCNs) are usually distinguished on conventional H&E-stained sections; however, the morphological heterogeneity in SCNs and hyperplasia of these ultimobranchial body remnants can mimic other diagnostic entities including but not limited to papillary microcarcinoma. In order to confirm the thyroid follicular epithelial origin and exclude the possibility of SCNs, most diagnosticians use immunohistochemical biomarkers of thyroid follicular epithelial cells and/or those of SCNs. While the expression profile of monoclonal PAX8 has not been reported previously in SCNs, the status of TTF-1 expression using the 8G7G3/1 clone has been inconsistent among several studies...

Astragalus membranaceus (AM) is one of 50 fundamental herbs in traditional Chinese medicine. Previous studies have shown that AM extract can be a potential nerve growth-promoting factor, being beneficial for the growth of peripheral nerve axons. We further investigated the effects of AM extract on regeneration in a rat sciatic nerve transection model. Rats were divided into three groups ([Formula: see text]): normal saline (intraperitoneal) as the control, and 1.5[Formula: see text]g/kg or 3.0[Formula: see text]g/kg of AM extract (every other day for four weeks), respectively...

Calcitonin gene-related peptide (CGRP) can cause migraines, yet it is also a potent vasodilator that protects against hypertension. Given the emerging role of CGRP-targeted antibodies for migraine prevention, an important question is whether the protective actions of CGRP are mediated by vascular or neural CGRP receptors. To address this, we have characterized the cardiovascular phenotype of transgenic nestin/hRAMP1 mice that have selective elevation of a CGRP receptor subunit in the nervous system, human receptor activity-modifying protein 1 (hRAMP1)...

INTRODUCTION: Greater splanchnic nerve (GSN) is by far the largest of the splanchnic nerves and connects the paravertebral and prevertebral ganglia to transmit the majority of nociceptive information from the viscera. Despite its importance, the immunohistochemical features of the porcine GSN neurons have not yet been examined. Therefore, the aim of the study was to investigate the neurochemistry of the porcine GSN neurons and to compare their neurochemical coding with those of the paravertebral and prevertebral ganglia...

A healthy woman volunteered to participate as "healthy control" in a study. An increased level of procalcitonin (PCT) was detected and remained elevated on follow-up measurements. As calcitonin levels were elevated as well, thyroid ultrasound was performed which revealed nodes in both thyroid lobes, one of them showing metabolic activity in positron emission tomography-computed tomography scan. To exclude a malignant thyroid cancer despite the negative findings in a fine needle aspiration the patient underwent thyroidectomy and a medullary thyroid carcinoma (MTC) was detected in the right lobe...

Unexplained chronic cough (UCC) affects millions of patients worldwide. New therapeutic approaches to this condition are urgently needed, since current treatment options provide only symptomatic relief. Cough reflex hypersensitivity has been shown to play an important role in the pathogenesis of UCC. The transient receptor potential vanilloid type 1 (TRPV1) is present on peripheral terminals of airway sensory nerves and modulation of its activity represents a potential target for the pharmacological treatment of UCC...

The calcitonin receptor (CTR) is a class B G protein-coupled receptor that is a therapeutic target for the treatment of hypercalcaemia of malignancy, Paget's disease and osteoporosis. In primates, the CTR is subject to alternative splicing, with a unique, primate-specific splice variant being preferentially expressed in reproductive organs, lung and kidney. In addition, humans possess a common non-synonymous single-nucleotide polymorphism (SNP) encoding a proline/leucine substitution in the C-terminal tail...
