CCK receptors significantly influence neurotransmission in the brain, regulating anxiety, feeding, and locomotion. CCK-B expression may correlate parallel to anxiety and depression phenotypes in humans. CCK-B receptors possess a complex regulation of dopamine activity in the brain. CCK-B activation appears to possess a general inhibitory action on dopamine activity in the brain, opposing the dopamine-enhancing effects of CCK-A. However, the effects of CCK-B on dopamine activity vary depending on location.[11] CCK-B antagonism enhances dopamine release in rat striatum.[12] Activation enhances GABA release in rat anterior nucleus accumbens.[13] CCK-B receptors modulate dopamine release, and influence the development of tolerance to opioids.[14] CCK-B activation decreases amphetamine-induced DA release, and contributes to individual variability in response to amphetamine.[15] In rats, CCK-B antagonism prevents the stress-induced reactivation of cocaine-induced conditioned place preference, and ...

The protein encoded by this gene belongs to the protein kinase D (PKD) family of serine/threonine protein kinases. This kinase can be activated by phorbol esters as well as by gastrin via the cholecystokinin B receptor (CCKBR) in gastric cancer cells. It can bind to diacylglycerol (DAG) in the trans-Golgi network (TGN) and may regulate basolateral membrane protein exit from TGN. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008] ...

GABA-ergic disturbances are hallmark features of many brain disorders. Two transgenic mouse lines were generated to suppress GAD1 in non-overlapping cell types that express cholecystokinin (CCK) or neuropeptide Y (NPY). In situ lipidomic and proteomic analyses on brain tissue sections revealed distinct, brain region specific profiles in each transgenic line. Behavioral analyses revealed that suppression of GAD1 in CCK+ interneurons resulted in locomotor and olfactory sensory changes while suppression in NPY+ interneurons affected anxiety-related behaviors and social interaction. Both transgenic mouse lines had altered sensitivity to amphetamine albeit in opposite directions. Together, these data argue that reduced GAD1 expression leads to altered molecular and behavioral profiles in a cell type-dependent manner, and that these two subpopulations of interneurons are strong and opposing modulators of dopamine system function. Furthermore, our findings also support the hypothesis that neuronal ...

Gastrin is a peptide hormone that stimulates secretion of gastric acid by the parietal cells of the stomach. Gastrin binds to a G-protein coupled receptor encoded by the CCKBR gene that also binds cholecystokinin (CCK), a brain regulatory peptide. The receptor is therefore known as the gastrin/cholecystokinin type B receptor. It is also known as cholecystokinin B receptor, cholecystokinin-2 receptor, CCK-B, CCKB-R, CCKRB, CCK2R, and GASR. The gastrin/cholecystokinin receptor is expressed mostly in central nervous system and the gastrointestinal tract. A misspliced transcript variant of the CCKBR gene that includes an intron has been associated with colorectal and pancreatic tumors.. ...

This work extends a recent observation that Otsuka Long-Evans Tokushima Fatty (OLETF) rats, which have been established as an animal model of non-insulin-dependent diabetes mellitus, show no expression of the cholecystokinin (CCK)-A receptor gene in the pancreas.

Cholecystokinin (CCK) is implicated in the regulation of nociceptive sensitivity of primary afferent neurons. Nevertheless, the underlying cellular and molecular mechanisms remain unknown. Using patch clamp recording, western blot analysis, immunofluorescent labelling, enzyme-linked immunosorbent assays, adenovirus-mediated shRNA knockdown and animal behaviour tests, we studied the effects of CCK-8 on the sensory neuronal excitability and peripheral pain sensitivity mediated by A-type K+ channels. CCK-8 reversibly and concentration-dependently decreased A-type K+ channel (IA) in small-sized dorsal root ganglion (DRG) neurons through the activation of CCK type B receptor (CCK-BR), while the sustained delayed rectifier K+ current was unaffected. The intracellular subunit of CCK-BR coimmunoprecipitated with Gαo. Blocking G-protein signaling with pertussis toxin or by the intracellular application of anti-Gβ antibody reversed the inhibitory effects of CCK-8. Antagonism of phosphatidylinositol 3-kinase

Cell surface proteins that bind cholecystokinin (CCK) with high affinity and trigger intracellular changes influencing the behavior of cells. Cholecystokinin receptors are activated by GASTRIN as well as by CCK-4; CCK-8; and CCK-33. Activation of these receptors evokes secretion of AMYLASE by pancreatic acinar cells, acid and PEPSIN by stomach mucosal cells, and contraction of the PYLORUS and GALLBLADDER. The role of the widespread CCK receptors in the central nervous system is not well understood. . ...

Previous studies suggest that cholecystokinin (CCK) is implicated in the modulation of pain sensitivity and the development of neuropathic pain. We used CCK(2) receptor deficient (CCK(2) (-/-)) mice and assessed their mechanical sensitivity using Von Frey filaments, as well as the development and time course of mechanical hyperalgesia in a model of neuropathic pain. We found that CCK(2) (-/-) mice displayed mechanical hyposensitivity, which was reversed to the level of wild-type animals after administration of naloxone (0.1-10 mg/kg). On the other hand, injection of L-365260 (0.01-1 mg/kg), an antagonist of CCK(2) receptors, decreased dose-dependently, mechanical sensitivity in wild-type mice. The mechanism of reduced mechanical sensitivity in CCK(2) (-/-) mice may be explained by changes in interactions between CCK and opioid systems. Indeed, CCK(2) (-/-) mice natively expressed higher levels of lumbar CCK(1), opioid delta and kappa receptors. Next, we found that CCK(2) (-/-) mice did not ...

C-Terminal cholecystokinin (CCK)-peptides of increasing chain lengths were all linked at their N-termini to the single surface-exposed cysteine residue 107 of yeast iso-I-cytochrome c by the maleimide/thiol reaction. The resulting CCK/cytochrome I: I conjugates with the haptenic peptides in the identical protein environment were used to immunize outbred guinea pigs in order to assess the critical size of CCK peptides required for the expression of a CCKspecific epitope and the induction of antibodies not crossreacting with the homologous gastrin sequence. By using standard ELISA techniques with polystyrene-adsorbed antigen to evaluate the specificity of the antisera, none of the conjugates were found to induce anti-CCK antisera not crossreacting with gastrin. However, when the biotinyl-CCK-antigen was immobilized by polystyrene-adsorbed avidin, i.e. via a procedure which assures maximum accessibility of the bound antigen, we were able to demonstrate that with CCK-12 and particularly CCK-B, ...

In addition to PV-expressing cells, cholecystokinin (CCK)-expressing GABAergic interneurons also innervate pyramidal cells (Fig. 1) at the soma and proximal dendrites (types 3 and 4), at the apical dendrites (type 9), at dendrites receiving glutamatergic CA3 input (type 8), and at the apical tuft (type 10). These CCK-expressing cells receive specific inputs from modulatory brain-stem nuclei (25) and fire different spike trains in vitro (26); their asynchronous GABA release causes longer-lasting inhibition in pyramidal cells (27); and their inhibitory effect is attenuated by postsynaptic pyramidal cells via cannabinoid receptors (28). Electrical stimulation of presynaptic fibers in vitro indicated that CCK-expressing cells may be particularly suited for integrating excitation from multiple afferents (29).. In vivo recordings of identified CCK-expressing cells in anesthetized rats (30) showed that CCK- and PV-expressing interneurons fire at distinct times (Fig. 2). During theta oscillations, ...

Hypergastrinemia in INS-GAS mice leads to accelerated carcinogenesis of the stomach, but the mechanisms have not been well defined. We investigated the possible role of gastrin-induced gastric cell apoptosis in the development of gastric cancer. We examined apoptosis and the expression of Bcl-2 family proteins in INS-GAS mice of different ages, as well as in gastrin-deficient (GAS-KO) mice after gastrin-17 (G-17) infusion. In addition, we studied the effects of the gastrin/cholecystokinin-2 (CCK-2) receptor antagonist YF476 and/or histamine H2 (H-2) receptor antagonist loxtidine on apoptosis and atrophy in INS-GAS mice with or without Helicobacter felis (H. felis) infection. INS-GAS mice had age-associated increases in Bax protein expression and decreases in Bcl-2 protein expression, along with increased glandular and epithelial cell apoptosis. At 8-week gastrin infusions in GAS-KO mice resulted in a similar pattern of altered Bax and Bcl-2 expression, followed by gastric cell apoptosis. H. felis

Receptor ligands, identified as antagonists, based on the absence of stimulation of signaling, can rarely stimulate receptor internalization. d-Tyr-Gly-[(Nle(28,31),d-Trp(30))CCK-26-32]-2-phenylethyl ester (d-Trp-OPE) is such a ligand that binds to the cholecystokinin (CCK) receptor and stimulates internalization. Here, the molecular basis of this trafficking event is explored, with the assumption that ligand binding initiates conformational change, exposing an epitope to direct endocytosis. Ligand-stimulated internalization was studied morphologically using fluorescent CCK and d-Trp-OPE. d-Trp-OPE occupation of Chinese hamster ovary cell receptors stimulated internalization into the same region as CCK. Arrestin-biased action was ruled out using morphological translocation of fluorescent arrestin 2 and arrestin 3, moving to the membrane in response to CCK, but not d-Trp-OPE. Possible roles of the carboxyl terminus were studied using truncated receptor constructs, eliminating the proline-rich distal tail

1. A scheme of synthesis was developped for cholecystokinin (CCK 26-33, using solid-phase methodology and successfully applied to the synthesis of its C- and N-terminal fragments. 2. Using CCK 30-33 as model, it was found that deprotection of the ?-phenacyl ester, with a 1 M solution of sodium thiophenoxide in DMF, leads to the formation of an aminosuccylnyl peptide, prior to ammonolysis. 3. Selenophenol reagent successfully removes the ?-phenacyl ester on protected CCK 32-33 and on protected CCK 30-33 polymer prior to ammonolytic cleavage of peptides from the resin. 4. Treatment of Boc-Asp(?-OPac)-Tyr(0-2,4-Dnp)-Met-Gly-Trp(Nin-For)-Met-Asp(?-OPac)-Phe-polymer with a 1 M solution of selenophenol in DMF, leads to irreversible rearrangement of the 0-2,4-dinitrophenyl ether. 5. Undesirable side-reactions can be avoided by sequential deprotections and cleavage. The 0-2,4-dinitrophenyl ether is removed by thiolysis following by selenolysis of the ?-phenacyl esters.

Introduction. Biological Explanations for Eating Behaviour The first study into eating behaviours was Canon and Wasburn (1912) they conducted a study in which the stomach would contract to indicate hunger and satiety. This research tells us that the strength of the gastric contraction correlated with the hunger and satiety of the participant. The participant was requested to push a button to indicate when they felt hungry. This shows that when we are hungry our brain sends signals to the stomach so that it can contract. A limitation of the study is that it contained one participant so it cannot be generalised. The part of the brain which receives signals of satiety is called the Ventromedial Hypothalamus it is located in the Hypothalamus and controls the amount we eat. ...read more. Middle. The hormone that is involved in signalling satiety is Cholecystokinin CCK which is the hormone released due to presence of food and sends signals to the VH to indicate satiety. CCK works when food passes from ...

The pancreas performs both exocrine and endocrine functions. The exocrine pancreas consists of two parts, the acinar and duct cells. The primary functions of pancreatic acinar cells are to synthesize and secrete digestive enzymes. Stimulation of the cell by secretagogues such as acetylcholine (ACh) and cholecystokinin (CCK) causes the generation of an intracellular Ca2+ signal. This signal, in turn, triggers the fusion of the zymogen granules with the apical plasma membrane, leading to the polarised secretion of the enzymes. The major task of pancreatic duct cells is the secretion of fluid and bicarbonate ions (HCO3-), which neutralize the acidity of gastric contents that enter the duodenum. An increase in intracellular cAMP by secretin is one of the major signals of pancreatic HCO3- secretion. Activation of the CFTR Cl- channel and the CFTR-dependent Cl-/HCO3- exchange activities is responsible for cAMP-induced HCO3- secretion ...

RESEARCH DESIGN AND METHODS - Two gastric emptying studies were performed on each of six type II diabetic patients. During one study, the patient ingested a glucose/protein solution, and during the other study, the patient ingested the same glucose/protein solution with the addition of 1.5 g of POT II, a putative stimulant of cholecystokinin (CCK) release. Each patient served as their own control subject. Each of the two oral solutions were administered to the patients in a ...

Sex hormones including estrogens affect brain areas involved in mood and cognition in addition to directly controlling reproduction and reproductive behavior. We studied the effect of pregnancy and puerperium on the concentrations of cholecystokinin (CCK), neuropeptide Y (NPY), substance P (SP) and galanin in tissue extracts from the rat striatum, frontal cortex and the hippocampal formation by means of radioimmunoassay. The most profound effects were found in the frontal cortex. Thus, cholecystokinin-like immunoreactivity (CCK-LI) was increased by 40 % during late pregnancy (p , 0.01) compared to estrous whereas SP-LI and galanin-LI decreased 25 % and 10 %, respectively. Postpartum, CCKLI decreased by 26% compared to pregnancy (p , 0.05) whereas SP-LI and galanin-LI were increased to a level above estrous (SP, P , 0.01; galanin, P , 0.05). No significant effect was observed in NPY-LI in this area. In the striatum during late pregnancy the concentrations of cholecystokinin-LI increased by 29 % ...

In the present study, we characterized the metabolic profile of the recently described lean Cck1r−/− rat on a Fischer 344 background. With our unique animal model, we hypothesized that the lean Cck1r−/− rats would show increased meal size and energy expenditure relative to their Fischer 344 wild-type counterparts. Cck1r−/− rats consumed larger meals during the dark cycle and smaller meals during the light cycle. These effects were accompanied by increased total spontaneous activity and energy expenditure during the dark cycle, as well as an apparent shift toward increased fat utilization as demonstrated by the reduction in RQ during the light cycle. On the basis of the findings in the OLETF rats (3), we predicted that both Cck1r+/+ and Cck1r−/− rats would show increased weight gain during chronic exposure to a highly palatable, HFD. Indeed, both Cck1r+/+ and Cck1r−/− rats were prone to DIO when maintained on a HFD, which was associated with increased serum leptin levels. We ...

Antibodies to the antral hormone gastrin have been induced in the rabbit and detected by passive hemagglutination. Specificity of the antibody, as determined by three methods, is directed to gastrins I and II, gastrin pentapeptide, and gastrin tetrapeptide, as well as to the stage-1 gastrin used for immunization.

TY - JOUR. T1 - Multiple kinases phosphorylate the pancreatic cholecystokinin receptor in an agonist-dependent manner. AU - Gates, L. K.. AU - Ulrich, C. D.. AU - Miller, L. J.. PY - 1993/1/1. Y1 - 1993/1/1. N2 - The cholecystokinin (CCK) receptor on the rat pancreatic acinar cell is a guanine nucleotide-binding protein (G protein)-coupled receptor, which was recently demonstrated to be phosphorylated in response to agonist stimulation (Klueppelberg et al., J. Biol. Chem. 266: 17744-17746, 1991). In this work, we establish that this receptor is phosphorylated in response to a variety of homologous and heterologous secretagogues and that these phosphorylation events represent action by more than one protein kinase. One subgroup of kinases includes one or more isotype of protein kinase C (PKC), and is capable of playing a role in homologous and heterologous desensitization. A second subgroup of kinases that acts on the CCK receptor was defined by its resistance to 10 μM staurosporine, which was ...

The mechanisms regulating the proliferation and differentiation processes that give rise to and maintain the gastric epithelium have not yet been completely elucidated.. In the present studies, in vitro models were established and the influence of growth factors and extracellular matrix proteins on these processes were investigated. Pentagastrin and hydrocortisone were found to accelerate the development of H,KTPase-positive parietal cells and other epithelial cells from undifferentiated gastric epithelial cells of foetal rats. These undifferentiated cells and also presumably immature epithelial cells in the progenitor zone of adult gastric glands were shown to express cholecystokinin-2 (CCK2) receptors and are therefore targets for the trophic action of gastrin.. H,K-ATPase-positive parietal cells in the progenitor zone of adult glands were also found to express CCK2 receptors, indicating that gastrin may stimulate maturation of the parietal cell lineage even during adult life. Parietal cells ...

The peptide hormone gastrin binds two ferric ions with high affinity and iron binding is essential for the biological activity of non-amidated gastrins and in the presence of Bi3+ ions the affinity of Fe3+ ions for Ggly was substantially reduced; the data was better fitted by a mixed rather than a competitive inhibition model. gastric mucosal damage induced by non-steroidal anti-inflammatory drugs aspirin or alcohol has also been noted with bismuth salts. In the colon treatment with bismuth reduced acid-induced colitis in rats [4 5 and microscopic [6] and ulcerative [7] colitis in humans. The bismuth salt most commonly used for treatment of gastrointestinal conditions in medical practice in Australia is currently colloidal bismuth subcitrate. Pharmacological studies have demonstrated that following absorption bismuth binds to plasma proteins [8] and is distributed through most tissues [9]. Gastrin is a gastrointestinal peptide hormone that was originally identified as a stimulant of acid ...

Oral NaCl produces stronger natriuresis and diuresis as compared with venous infusion of same amount of NaCl, indicating the existence of renal-gastric axis. Although numerous hormones are secreted in gastrointestinal tract, gastrin is evident one due to its natriuretic effects and taken-up by the renal proximal tubule (RPT) cells. We hypothesize that there is an interaction between gastrin and dopamine receptor in kidney, which synergistically increases sodium excretion, the impaired interaction would be involved in the pathogenesis of hypertension. In WKY rats, infusion of gastrin, via renal artery, induced natriuresis and diuresis, which was blocked in the presence of CI988, a gastrin receptor blocker. Similarly, the natriuretic and diuretic effect of fenoldopam, a D1-like receptor agonist, was blocked by the D1-like receptor antagonist, SCH23390, indicating that gastrin and fenoldopam, via individual receptor, play natriuretic and diuretic effects. Our further study found that lower dosages ...

Cholecystokinin (CCK) is a unique peptide released by the duodenal I cells in response to chyme containing high fat or protein content. Unlike secretin, which is an endocrine hormone, CCK actually works via stimulation of a neuronal circuit, the end-result of which is stimulation of the acinar cells to release their content.[5] CCK also increases gallbladder contraction, causing release of pre-stored bile into the cystic duct, and eventually into the common bile duct and via the ampulla of Vater into the second anatomic position of the duodenum. CCK also decreases the tone of the sphincter of Oddi, which is the sphincter that regulates flow through the ampulla of Vater. CCK also decreases gastric activity and decreases gastric emptying, thereby giving more time to the pancreatic juices to neutralize the acidity of the gastric chyme ...

Abstract(s) :. (Anglais) Cholecystokinin (CCK) / sulfakinin (SK)-type neuropeptides regulate feeding and 37 digestion in chordates and protostomes (e.g. insects). Here we characterised CCK/SK-type 38 signalling for the first time in a non-chordate deuterostome - the starfish Asterias rubens 39 (phylum Echinodermata). In this species, two neuropeptides (ArCCK1, ArCCK2) derived from 40 the precursor protein ArCCKP act as ligands for a CCK/SK-type receptor (ArCCKR) and are 41 expressed in the nervous system, digestive system, tube feet and body wall. Furthermore, 42 ArCCK1 and ArCCK2 cause dose-dependent contraction of cardiac stomach, tube foot and 43 body wall apical muscle preparations in vitro and injection of these neuropeptides in vivo 44 triggers cardiac stomach retraction and inhibition of the onset of feeding in A. rubens. Thus, an 45 evolutionarily ancient role of CCK/SK-type neuropeptides as inhibitory regulators of feeding- 46 related processes in the Bilateria has been conserved in the ...

The disruption in glucose homeostasis characteristic of diabetes and obesity is due partly to an increase in glucose production (GP). However, the mechanisms underlying the regulation of GP in healthy and obese/diabetic settings remain to be elucidated. A duodenal Intralipid infusion activates a duodenal PKC-δ - cholecystokinin (CCK) - CCK1 receptor - PKA neuronal signaling cascade to lower GP. Intralipid is an emulsion of fatty acids containing the highest percentage of linoleic acid (LA; polyunsaturated fatty acid) and oleic acid (OA; monounsaturated fatty acid). The relative ability of individual duodenal fatty acids to regulate GP is currently unknown, as are the potential mechanisms. Therefore, we investigated whether LA and OA lower GP when infused into the duodenum and whether they utilize similar mechanisms as Intralipid in rats and mice in vivo. First, anintraduodenal infusion of OA or LA lowered GP during the pancreatic (basal insulin) euglycemic clamps. Second, co-infusion of ...

Neocortical neurones can be classified according to several independent criteria: morphological, physiological, and molecular expression (neuropeptides (NPs) and/or calcium-binding proteins (CaBPs)). While it has been suggested that particular NPs and CaBPs characterize certain anatomical subtypes of neurones, there is also considerable overlap in their expression, and little is known about simultaneous expression of multiple NPs and CaBPs in morphologically characterized neocortical neurones. Here we determined the gene expression profiles of calbindin (CB), parvalbumin (PV), calretinin (CR), neuropeptide Y (NPY), vasoactive intestinal peptide (VIP), somatostatin (SOM) and cholecystokinin (CCK) in 268 morphologically identified neurones located in layers 2-6 in the juvenile rat somatosensory neocortex. We used patch-clamp electrodes to label neurones with biocytin and harvest the cytoplasm to perform single-cell RT-multiplex PCR.

We employed dual probe microdialysis in the nucleus accumbens and ipsilateral ventral pallidum of the halothane anaesthetized rat to investigate the effect of intra-accumbens perfusion with the sulphated octapeptide cholecystokinin (CCK-8S, 10-1000 nM, 60 min) alone and in the presence of the selective CCK1 and CCK2 receptor antagonists L-364,718 (10 and 100 nM) and PD134308 (10 nM), tetrodotoxin (TTX, 1000 nM) and the GABA(A) receptor antagonist bicuculline (1000 nM), on dialysate GABA levels in the ventral pallidum ...

Cholecystokinin (CCK) modulates contractility of the gallbladder, the sphincter of Oddi, and the stomach. These effects are mediated through activation of gastrointestinal smooth muscle as well as enteric neuron CCK-1 receptors (CCK-1Rs). To investigate the potential physiological and pathophysiological functions linked to CCK-1R-mediated signaling, we compared male WT and CCK-1R-deficient mice (129/SvEv). After 12 weeks on either a standard mouse chow or a lithogenic diet (containing 1% cholesterol, 0.5% cholic acid, and 15% dairy fat), small-intestinal transit time, intestinal cholesterol absorption, biliary cholesterol secretion, and cholesterol gallstone prevalence were compared in knockout versus WT animals. Analysis of mice on either the chow or the lithogenic diet revealed that CCK-1R-/- animals had larger gallbladder volumes (predisposing to bile stasis), significant retardation of small-intestinal transit times (resulting in increased cholesterol absorption), and increased biliary ...

OP hypertensive animals had significantly PCI-32765 clinical trial reduced Fos-like immunoreactivity in the nucleus of the soliltary tract and the caudal ventrolateral medulla in response to CCK when compared to controls and/or OR animals, indicative of impaired signalling pathways in. the brainstem within the reflex circuit between vagal afferents and presympathetic RVLM neurons. Blunted sympathoinhibitory responses in obesity-related hypertension are associated with blunted responses in RVLM neurons as a result of aberrant central but not peripheral signalling mechanisms. The gut hormone cholecystokinin (CCK) acts at subdiaphragmatic vagal afferents to induce renal and splanchnic sympathoinhibition and vasodilatation, via reflex inhibition of a subclass of cardiovascular-controlling neurons in the rostroventrolateral medulla (RVLM). These sympathoinhibitory and vasodilator responses are blunted in obese, hypertensive rats and our aim in the present study was to determine whether this is ...

TY - JOUR. T1 - Nutrient inhibition of ghrelin secretion in the fasted rat. AU - Gomez, Guillermo. AU - Englander, Ella. AU - Greeley, George H.. PY - 2004/1/15. Y1 - 2004/1/15. N2 - Ghrelin is a recently discovered stomach hormone whose secretion increases with fasting; the fasting-induced elevation is inhibited by refeeding. The aim of this study was to determine whether all nutrient types (i.e., carbohydrates, proteins, fats) and soybean trypsin inhibitor (SBTI), a secretagogue for intestinal cholecystokinin (CCK), given individually into the stomach or intravenously can inhibit ghrelin secretion in the fasted rat. Intragastric (i.g.) administration of intact protein, a protein digest, SBTI, dextrose, or fat decreased plasma ghrelin levels significantly (p,0.05). All nutrients inhibited ghrelin secretion equally. Fat and dextrose given intravenously (i.v.) also reduced ghrelin secretion. These data demonstrate that nutrients can inhibit ghrelin secretion by both the luminal and systemic ...

Eating disorders such as anorexia (AN) and bulimia nervosa (BN) are characterized by abnormal eating behavior. The essential aspect of AN is that the individual refuses to maintain a minimal normal body weight. The main features of BN are binge eating and inappropriate compensatory methods to prevent weight gain. The gut-brain-adipose tissue (AT) peptides and neutralizing autoantibodies play an important role in the regulation of eating behavior and growth hormone release. The mechanisms for controlling food intake involve an interplay between gut, brain, and AT. Parasympathetic, sympathetic, and serotoninergic systems are required for communication between brain satiety centre, gut, and AT. These neuronal circuits include neuropeptides ghrelin, neuropeptide Y (NPY), peptide YY (PYY), cholecystokinin (CCK), leptin, putative anorexigen obestatin, monoamines dopamine, norepinephrine (NE), serotonin, and neutralizing autoantibodies. This extensive and detailed report reviews data that demonstrate that
