Dopamine and cholecystokinin (CCK) are recognized as two critical neurotransmitters involved in the control of food intake; however, the potential interactions between these neurotransmitters remain poorly understood. Consequently, this study aimed to investigate the interactions between central CCK and the dopaminergic system in the feeding behavior of layer-type chickens. In this experiment, birds were administered intracerebroventricular (ICV) injections of CCK4, CCK8, and CCK8s at doses of 0.25, 0.5, and 1 nmol, respectively. Additionally, various compounds were injected ICV, including L-DOPA (a dopamine precursor), 6-OHDA (a dopamine synthesis inhibitor), SCH 23390 (a D1 receptor antagonist), AMI-193 (a D2 receptor antagonist), NGB 2904 (a D3 receptor antagonist), and L-741,742 (a D4 receptor antagonist), either alone or in combination with CCK8s (1 nmol). The cumulative feed consumption was measured at 30, 60, and 120 minutes following the injections. The results indicated that ICV administration of CCK4 and CCK8 did not significantly influence feeding behavior (P ≥ 0.05). In contrast, CCK8s at a dose of 1 nmol resulted in a dose-dependent reduction in feed consumption (P < 0.05). Furthermore, SCH 23390 (5 nmol) and 6-OHDA (150 nmol) mitigated the inhibitory effect of CCK8s on feed consumption (P < 0.05), whereas NGB2904 (6.4 nmol), AMI-193 (5 nmol), and L-741,742 (6 nmol) did not exhibit significant effects (P ≥ 0.05).

Increased M<sub>1</sub> and M<sub>2</sub> muscarinic receptor expression in brain regions during fasting, and reversal of changes by refeeding may contribute to these seizures. Since receptor expression is regulated in response to agonist stimulation, this study investigated effects of nonselective muscarinic receptor agonist oxotremorine on convulsions in fasted animals. Mice deprived of food for 24h were given oxotremorine during (0.1mg/kg, twice daily, s.c.) or after (0.05 or 0.1mg/kg, i.p.) fasting. Fasted animals were treated with saline or scopolamine (i.p.) and observed for 30min for the convulsions after being allowed to eat ad libitum. Oxotremorine administration during fasting produced no significant effect on convulsion development. Incidence and onset of convulsions, and seizure stages were indifferent between the scopolamine and oxotremorine - scopolamine groups. However, oxotremorine (0.1mg/kg) administration after fasting reduced incidence of convulsions. Resulting from an agonist-antagonist interaction at M<sub>1</sub> and/or M<sub>2</sub> muscarinic receptors, oxotremorine administered after fasting exhibited an anticonvulsant activity. Oxotremorine administration during fasting was expected to suppress seizure development via inhibition of receptor expression. Results did not confirm this expectation and suggested that muscarinic receptor expression was either not affected or not related to the convulsions.

It is considered a pandemic, with its prevalence constantly rising in Western countries. As a result, numerous studies have focused on understanding the elements that contribute to obesity. Researchers have focused on neurotransmitters in the brain to develop weight management drugs that regulate food intake. This review explores the literature on genetic influences on dopaminergic processes to determine whether genetic variation has an association with obesity in reward-responsive regions, including mesolimbic efferent and mesocortical areas. Various neurotransmitters play an essential role in regulating food intake, such as dopamine which controls through mesolimbic circuits in the brain that modulate food reward. Appetite stimulation, including primary reinforcers such as food, leads to an increase in dopamine release in the reward centers of the brain. This release is related to motivation and reinforcement, which determines the motivational weighting of the reinforcer. Changes in dopamine expression can lead to hedonic eating behaviors and contribute to the development of obesity. Genetic polymorphisms have been investigated due to their potential role in modulating the risk of obesity and eating behaviors. Therefore, it is crucial to assess the impact of genetic alterations that disrupt this pathway on the obesity phenotype.</p>","PeriodicalId":8823,"journal":{"name":"Behavioural Brain Research","volume":" ","pages":"115401"},"PeriodicalIF":2.6,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These systems are ultimately finely tuned by hypothalamic and extrahypothalamic neurocircuitry that modulate feeding and the appetite signalling cascade. The hypothalamus has been extensively researched and its role in homeostatic regulation of energy balance is well established. Later on, evidence indicated that extrahypothalamic signalling also has a critical role in regulation of body mass across the lifespan. One of these brain regions was the brainstem and specifically the dorsal vagal complex (DVC), which comprises of the area postrema (AP), nucleus of the solitary tract (NTS) and dorsal motor complex of the vagus (DMV). These brain stem nuclei were shown to also finely tune feeding behaviour through catecholaminergic, glutamatergic, and GABAergic signals. Moreover, these nuclei also receive afferent signals from the viscera through the gut, as well as humoral input from the bloodstream. Therefore, these brain stem nuclei are deemed as the port of entry where initial appetite-related signals are first conveyed and then modulated to the forebrain to hypothalamic and extrahypothalamic regions such as the arcuate nucleus (ARC) and parabrachial nucleus (PBN). Understanding the intricate interactions and projections between hypothalamic and brainstem nuclei is instrumental to comprehend energy balance regulation as a whole and to potentially address metabolic conditions such as diabetes and obesity.
