Substance P (SP) and neurotensin (NT) are neuropeptides isolated in the periphery and in the central nervous system. They are involved in various regulatory processes in the gastrointestinal tract, in the circulatory and respiratory systems, kidney and endocrine system. In addition to the peripheral effects, SP and NT act as neurotransmitters and neuromodulators in the central nervous system, regulating various behavioural actions, such as general and motor activity, pain, food and water intake, anxiety, reward/reinforcement and memory consolidation...

Neurotensin (NTS) has long been recognized as a neurotransmitter or neuromodulator in the central nervous system and as an endocrine agent in the periphery via actions mediated through neurotensin receptors (NTSRs). Many studies support a role for NTS in the endocrine, autocrine and paracrine growth stimulation of cancer, with oncogenic actions described for NTS in different types of cancers and cancer cell lines at each step of cancer progression, ranging from tumour growth and survival to metastatic spread...

REVIEW
Gareth Leng, Nancy Sabatier
Mammalian neurons that produce oxytocin and vasopressin apparently evolved from an ancient cell type with both sensory and neurosecretory properties that probably linked reproductive functions to energy status and feeding behavior. Oxytocin in modern mammals is an autocrine/paracrine regulator of cell function, a systemic hormone, a neuromodulator released from axon terminals within the brain, and a 'neurohormone' that acts at receptors distant from its site of release. In the periphery oxytocin is involved in electrolyte homeostasis, gastric motility, glucose homeostasis, adipogenesis, and osteogenesis, and within the brain it is involved in food reward, food choice, and satiety...

Calcitonin gene-related peptide (CGRP) is a multifunctional neuropeptide produced as a consequence of alternative RNA processing of the calcitonin gene. CGRP is widely distributed in the nervous system, particularly at anatomical areas thought to be involved with migraine pathophysiology, including the trigeminovascular nociceptive system. Over the past two decades, a convergence of basic and clinical evidence has established the CGRP as a key player in migraine. CGRP enhances sensitivity to sensory input at multiple levels in both the periphery and central nervous system...

Pain in extremities may occur in a variety of central and peripheral neuropathic and nociceptive syndromes, some of which may respond to central neuromodulation procedures. Peripheral neuromodulation techniques, either as a stand-alone therapy or as an adjuvant to spinal cord stimulation, may be particularly effective when the pain is localized to a part of a single extremity or when the source of the pain is related to the malfunction of a known peripheral nerve. Further, peripheral neuromodulation is used to treat disorders in which central simulation fails to provide discrete therapeutic paresthesia...

The urotensin II (UII) gene family consists of four paralogous genes called UII, UII-related peptide (URP), URP1 and URP2. UII and URP peptides exhibit the same cyclic hexapeptide core sequence (CFWKYC) while the N- and C-terminal regions are variable. UII, URP1, and URP2 mRNAs are differentially expressed within the central nervous system of teleost fishes, suggesting that they may exert distinct functions. Although the cardiovascular, ventilatory and locomotor effects of UII have been described in teleosts, much less is known regarding the physiological actions of URPs...

REVIEW
Anastasia Hodes, David Lichtstein
Natriuretic hormones (NH) include three groups of compounds: the natriuretic peptides (ANP, BNP and CNP), the gastrointestinal peptides (guanylin and uroguanylin), and endogenous cardiac steroids. These substances induce the kidney to excrete sodium and therefore participate in the regulation of sodium and water homeostasis, blood volume, and blood pressure (BP). In addition to their peripheral functions, these hormones act as neurotransmitters or neuromodulators in the brain. In this review, the established information on the biosynthesis, release and function of NH is discussed, with particular focus on their role in brain function...

Deep body temperature (Tb) is kept relatively constant despite a wide range of ambient temperature variation. Nevertheless, in particular situations it is beneficial to decrease or to increase Tb in a regulated manner. Under hypoxia for instance a regulated drop in Tb (anapyrexia) is key to reduce oxygen demand of tissues when oxygen availability is diminished, leading to an increased survival rate in a number of species when experiencing low levels of inspired oxygen. On the other hand, a regulated rise in Tb (fever) assists the healing process...

Opioid peptides and their receptors have been localized to the inner ear of the rat and guinea pig mammalian models. The expression of mu opioid receptor (MOR) in the human and mouse cochlea is not yet known. We present MOR protein localization by immunohistochemistry and mRNA expression by in situ hybridization in the human and mouse spiral ganglia (SG) and organ of Corti. In the human most of the (SG) neurons were immunoreactive; a subset was non-immunoreactive. In situ hybridization revealed a similar labeling pattern across the neurons of the SG...

Olfactory sensitivity exhibits daily fluctuations. Several studies have suggested that the olfactory system in insects is modulated by both biogenic amines and neuropeptides. However, molecular and neural mechanisms underlying olfactory modulation in the periphery remain unclear since neuronal circuits regulating olfactory sensitivity have not been identified. Here, we investigated the structure and function of these signaling pathways in the peripheral olfactory system of the American cockroach, Periplaneta americana, utilizing in situ hybridization, qRT-PCR, and electrophysiological approaches...

Gastrin-releasing peptide (GRP), a neuropeptide initially isolated from porcine stomach, shares sequence similarity with bombesin. GRP and its receptors are present in the brains and peripheral tissues of several species of teleost fish, but little is known about the ventilatory and cardiovascular effects of this peptide in these vertebrates. The goal of this study was to compare the central and peripheral actions of picomolar doses of trout GRP on ventilatory and cardiovascular variables in the unanesthetized rainbow trout...

We describe an angiotensin (Ang) II-containing innervation of the kidney. Cryosections of rat, pig and human kidneys were investigated for the presence of Ang II-containing nerve fibers using a mouse monoclonal antibody against Ang II (4B3). Co-staining was performed with antibodies against synaptophysin, tyrosine 3-hydroxylase, and dopamine beta-hydroxylase to detect catecholaminergic efferent fibers and against calcitonin gene-related peptide to detect sensory fibers. Tagged secondary antibodies and confocal light or laser scanning microscopy were used for immunofluorescence detection...

Nociception, the encoding and processing of noxious environmental stimuli by sensory neurons, functions to protect an organism from bodily damage. Activation of the terminal endings of certain sensory neurons, termed nociceptors, triggers a train of impulses to neurons in the spinal cord. Signals are integrated and processed in the dorsal spinal cord and then projected to the brain where they elicit the perception of pain. A number of neuromodulators that can affect nociceptors are released in the periphery during the inflammation that follows an initial injury...

Lysolipids are important mediators of cellular communication in multiple physiological processes. Sphingosine-1-phosphate (S1P) is a major lysolipid in many organs, including the central nervous system (CNS). This commentary discusses recent findings on the role of S1P in regulating pain perception, and highlights advances and challenges in the field. S1P interacts with multiple cellular targets, including G-protein-coupled receptors. Known S1P receptors include five types, four of which are expressed in the CNS (S1P(1,2,3,5)) where they are localized on neurons and glia...

Histamine is recognized as a neurotransmitter or neuromodulator in the brain, and it plays a major role in the pathogenic progression after cerebral ischemia. Extracellular histamine increases gradually after ischemia, and this may come from histaminergic neurons or mast cells. Histamine alleviates neuronal damage and infarct volume, and it promotes recovery of neurological function after ischemia; the H1, H2, and H3 receptors are all involved. Further studies suggest that histamine alleviates excitotoxicity, suppresses the release of glutamate and dopamine, and inhibits inflammation and glial scar formation...

In the brains of teleosts, angiotensin II (ANG II), one of the main effector peptides of the renin-angiotensin system, is implicated in various physiological functions notably body fluid and electrolyte homeostasis and cardiovascular regulation, but nothing is known regarding the potential action of ANG II and other angiotensin derivatives on ventilation. Consequently, the goal of the present study was to determine possible ventilatory and cardiovascular effects of intracerebroventricular injection of picomole doses (5-100 pmol) of trout [Asn(1)]-ANG II, [Asp(1)]-ANG II, ANG III, ANG IV, and ANG 1-7 into the third ventricle of unanesthetized trout...

Calcitonin gene-related peptide (CGRP) and its receptors are widely distributed in the tissues of teleost fish, including the brain, but little is known about the ventilatory and cardiovascular effects of the peptide in these vertebrates. The present study was undertaken to compare the central and peripheral actions of graded doses (5-50 pmol) of trout CGRP on ventilatory and cardiovascular variables in unanesthetized rainbow trout. Compared with vehicle, intracerebroventricular injection of CGRP significantly elevated the ventilation frequency (f(V)) and the ventilation amplitude (V(AMP)) and, consequently, the total ventilation (V(TOT))...

There is widespread evidence in favour of nitric oxide (NO) acting as a gaseous neurotransmitter in the central nervous system, diffusing from its cells of origin and affecting surrounding neuronal tissue in evanescent three-dimensional waves. This is also true of the hypothalamus, where amongst other activities NO inhibits stimulation of corticotrophin-releasing hormone (CRH) and vasopressin release by inflammatory stressors, effects thought to be mediated by binding with soluble guanylate cyclase (sGC). Carbon monoxide is being increasingly recognised as another gaseous neuromodulator, but with principal effects on other hemoproteins such as cyclo-oxygenase, and a distinctly different profile of localisation...

Dextromethorphan (DM) is a well-known antitussive dextrorotatory morphinan. We and others have demonstrated that sigma (σ) receptors may be important for DM-mediated neuromodulation. Because an earlier report suggested that DM might affect sexual function and that σ receptor ligands affect signaling pathways in the periphery, we examined whether DM-induced psychotoxic burden affected male reproductive function. We observed that DM had a high affinity at σ-1 receptors in the brain and testis but relatively low affinity at σ-2 receptors...

Irritable Bowel Syndrome (IBS) is a functional gastrointestinal (GI) disorder, characterized by abdominal pain, altered bowel habit (diarrhea and/or constipation), and bloating in the absence of demonstrable organic pathology. It is the most common GI disorder seen in primary care and gastroenterology practices. Conservative therapies for IBS are directed at both pain and correction of altered GI motility. A small proportion of patients with IBS have severe or refractory symptoms and report constant pain. IBS is no longer considered solely a disorder of motility, but rather its clinical expression is viewed as dysregulation of CNS-enteric function...
