“…In contrast to those of several birds studied by Yamada et al (1985), data from this study show that GRP, Som, and nNOS all occasionally occur in the epithelial layer of the gastric glands of the proventriculus of the Houbara bustard. In addition, while the distribution of GRP in the proventriculus is similar to that of the pigeon, quail, chicken, gull, and kite it differs from that of duck and the finch.…”

“…The neurotransmitters present in endocrine cells include gastrin-releasing peptide, somatostatin, and neuronal nitric oxide synthase. Other studies have identified GRP and Som as the main neuropeptides present in endocrine cells of the avian proventriculus (Alumets et al, 1977;Yamada et al, 1985;Yamanaka et al, 1989). In addition, glucagon (Rawdon and Andrew, 1981), avian polypeptide (Alumets et al, 1978;Rawdon and Andrew, 1981), and neurotensin (Rawdon and Andrew, 1981;Usellini et al, 1983) have been identified in the chicken proventriculus.…”

“…In addition, while the distribution of GRP in the proventriculus is similar to that of the pigeon, quail, chicken, gull, and kite it differs from that of duck and the finch. GRP cells occur in the middle of the submucosal glands of the duck but are dispersed throughout glandular lobules of the finch (Yamada et al, 1985). Other workers (Martinez et al, 1991) found bombesin or GRP-immunoreactive endocrine cells in the inner portions of the submucosal glands of newborn farm chicks.…”

“…Although the topographical distribution of GRP and Som in endocrine cells of the proventriculus has been established in several avian species, there are variations in their distribution and frequency (Yamada et al, 1985). There is thus justification for examining their distribution in other avian species such as the Houbara bustard, which is being captive-bred.…”

Endocrine cells containing somatostatin (Som), gastrin-releasing peptide (GRP), and neuronal nitric oxide synthase (nNOS) and nerve fibers containing choline acetyl transferase (ChAT), tyrosine hydroxylase (TH), galanin (Gal), substance P (SP), and vasoactive intestinal polypeptide (VIP) were immunolocalized in the proventriculus of the Houbara bustard, Chlamydotis undulata. While GRP-immunoreactive (GRP-IR) cells occur in the inner zone, somatostatin (Som-IR) and polyclonal nNOS (nNOS-IR) immunoreactive cells were localized mainly in the peripheral zone of submucosal glands. GRP-IR, Som-IR, and nNOS-IR cells were occasionally observed in the walls of the gastric glands. Endocrine cells are of the closed variety and usually possess apical processes extending along the basal surfaces of adjacent nonreactive cells. Ultrastructural features of these cells are typical. ChAT, Gal, SP, VIP, and TH were immunolocalized in nerve fibers and terminals in the walls of arterioles and capillaries at the periphery of submucosal glands. Immunoreactivity to monoclonal nNOS occurred mainly in neuronal cell bodies in ganglia located around the submucosal glands. ChAT and TH immunoreactive cell bodies were also occasionally seen around the submucosal glands in the peripheral region. Immunoreactivity to Gal, SP, and VIP, but not ChAT or TH, was discernible around the walls of gastric glands. It was concluded that the distribution of neurotransmitters in neuronal structures is similar, but that of the endocrine cells varies from that of some avian species. The roles of these neurotransmitters in the regulation of acid secretion are discussed.

“…In birds, the amygdaloid complex includes the nucleus posterior amygdalopallialis (PoA), the TnA, and the area subpallialis amygdalae (SpA), and has been linked to visceral and limbic functions because of its connections with the hypothalamus and caudal brain stem nuclei. A dense 5-HT innervation was found for limbic structures like the TnA, the parahippocampal area (APH), hippocampus (HP), and area septalis in pigeons, chicken, and quails (Yamada et al, 1985;Cozzi et al, 1991;Challet et al, 1996). Recently it was shown that injections of the 5-HT 1/2/7 receptor antagonist Metergoline and the 5-HT 1B/1D agonist GR46611 into TnA induced hypophagic responses, whereas the same treatment in the arcopallium intermedium (AI) resulted in a selective increase in water intake (Campanella et al, 2009).…”

Serotonin 5-HT1A receptor binding sites in the brain of the pigeon (Columba livia)

et al. 2012

Serotonin (5-HT) is a modulatory neurotransmitter that is involved in a variety of physiological and behavioral functions. In mammals, dysfunction of the serotonergic system has been linked to various diseases such as depression, schizophrenia, Alzheimer's disease, and eating disorders (Müller et al., 2007;Michelsen et al., 2008;Remington, 2008;Terry et al., 2008;Akimova et al., 2009;Polter and Li, 2010). In addition, growing evidence found in many species indicates that 5-HT modulates learning and memory (Jacobs and Azmitia, 1992;Winsauer et al., 1996; Meneses, 1999;Clarke et al., 2004; Meneses and PerezGarcia, 2007;Müller et al., 2007;Bert et al., 2008;Gasbarri et al., 2008;González-Burgos and Feria-Velasco, 2008;Sitaraman et al., 2008;Sambeth et al., 2009;Bari et al., 2010).Serotonin binds to multiple receptors (Hoyer et al., 2002;Green, 2006), which are widely distributed throughout the brain (Chalmers and Watson, 1991;Baumgarten and Grozdanovic, 1995;Barnes and Sharp, 1999;Riad et al., 2000). One of the most prominent is the 5-HT 1A receptor, which was first cloned and described by Fargin et al. (1988). The 5-HT 1A receptor belongs to the G protein coupled receptor superfamily and binds to a Gi/o protein (Innis and Aghajanian, 1987;Polter and Li, 2010). It displays a high affinity for 5-HT and occurs both pre-and postsynaptically (Hall et al., 1985;van Wijngaarden et al., 1990;Riad et al., 2000). As somatodendritic autoreceptors, 5-HT 1A receptors modulate the activity of 5-HT neurons, whereas they modify neuronal activity in terminal areas as postsynaptic receptors (Müller et al., 2007).The distribution of 5-HT 1A receptors in the brain has been investigated by several methods in rodents, nonhuman primates, and humans. Thereby, a high correlation between receptor binding with [3H]-8-hydroxy-2-(di-n-propylamino)tetralin ([ 3 H]-8-OH-DPAT) and 5-HT 1A mRNA densities has been shown (Chalmers and Watson, 1991;Pompeiano et al., 1992). High 5-HT 1A receptor densities were detected in the dorsal and median raphe nuclei and in areas of the limbic system such as the hippocampus, the lateral septum, the amygdala, as well as the entorhinal and cingulate cortices Zilles et al., 1985Zilles et al., , 2000Palacios et al., 1990;Yilmazer-Hanke et al., 2003). Moderate binding was detected in the olfactory bulb, the thalamus, hypothalamus, and several brain stem nuclei as well as neocortical areas. Low levels, or no binding, were reported in the basal ganglia and cerebellum (Gozlan et al., 1983;Marcinkiewicz et al., 1984;Zilles et al., 1985Zilles et al., , 2000Hall et al., 1997;Vergé et al., 1986;Albert et al., 1990;Palacios et al., 1990;Pompeiano et al., 1992;Khawaja, 1995; Kia et al., 1996a,b;Farde et al., 1997;Raurich et al., 1999;Hume et al., 2001;Maeda et al., 2001;Geyer et al., 2005;Palchaudhuri and Flügge, 2005;Eickhoff et al., 2007;Topic et al., 2007). 5-HT 1A receptors play a role in executive functions, anxiety related behavior, learning and reinforcement, feeding behavior, and locomotor activity (Zilles et al., 2...

Distribution of serotonin-immunoreactive gut endocrine cells in chicks at hatching

Serotonin-immunoreactive, i.e. enterochromaffin (EC) cells were found to be widely distributed in the intestine of the newly hatched chick but sparse in the stomach, and being particularly abundant in the duodenum, upper ileum and rectum. Although in birds, as in mammals, EC cells are most abundant in the intestine, in the stomach they are far sparser than in mammals. Comparison of adjacent sections immunostained for serotonin and a peptide provided no evidence that EC cells in the hatching chick contain motilin or substance P, and that at least the great majority of bombesin-immunoreactive cells contain no serotonin: it is apparent that the mammalian pattern of distribution of peptides in EC cells does not occur in the chick, at least at hatching. Cross reaction of an antiserum to substance P with serotonin was discovered, suggesting the need for a review of existing evidence for co-localisation of this peptide with serotonin.
