Impaired hypothalamic cocaine ‐ and amphetamine‐regulated transcript expression in lateral hypothalamic area and paraventricular nuclei of dehydration‐induced anorexic rats
We examined whether changes in CART expression from the lateral hypothalamic area (LHA) and arcuate nucleus (ARC) could participate in food‐avoidance of DIA rats. DIA and forced‐food restricted (FFR) animals reduced their body weight and food intake. FFR rats had a down‐regulation of their HPT axis (reduced serum TH and TSH content), whereas DIA animals had reduced TH but increased TSH levels. CART mRNA expression in the ARC decreased similarly between experimental groups and diminished in anterior, medial PVN and in LHA of FFR animals, whereas DIA animals showed unchanged levels. This impaired CART mRNA expression i...

Neonatal overfeeding by small ‐litter rearing sensitises hippocampal microglial responses to immune challenge: Reversal with neonatal repeated injections of saline or minocycline
Abstract
The early‐life period is extremely vulnerable to programming effects from the environment, many of which persist into adulthood. We have previously demonstrated that adult rats overfed as neonates have hypothalamic microglia that are hyper‐responsive to an immune challenge, as well as hippocampal microglia that respond less efficiently to learning. We therefore hypothesised that neonatal overfeeding would alter the ability of hippocampal microglia to respond to an immune challenge with lipopolysaccharide (LPS) and that concomitant minocycline, a tetracycline antibiotic that suppresses microglial activity, coul...

Diurnal and photoperiodic changes in Thyrotrophin stimulating hormone β (TSHβ) expression, and associated regulation of deiodinase enzymes (DIO2, DIO3) in the female juvenile chicken hypothalamus
This study aimed to determine the relationship between long‐photoperiods (LP) and diurnal TSHβ gene expression in the juvenile chicken by comparing LP‐photostimulated birds with groups kept on short photoperiods (SP) for 1 or 12 days. TSHβ expression increased 3 and 23‐fold after 1 and 12 days LP‐photostimulation both during the day and at night. In both SP and LP conditions, TSHβ expression was between 3 and 14‐fold higher at night than in the day, suggesting that TSHβ expression cycles in a diurnal pattern irrespective of photoperiod. The ratio of DIO2/3 was decreased on LPs, consequent upon changes in DIO3...

Regulation of hypothalamic corticotropin ‐releasing hormone neurone excitability by oxytocin
Oxytocin (OT) is a neuropeptide that exerts multiple actions throughout the brain and periphery. Within the brain, OT regulates diverse neural populations, including neural networks controlling responses to stress. Local release of OT within the paraventricular nucleus (PVN) of the hypothalamus has been suggested to regulate stress responses by modulating the excitability of neighbouring corticotropin‐releasing hormone (CRH) neurones. However, the mechanisms by which OT regulates CRH neurone excitability are unclear. In the present study, we investigated the morphological relationship between OT and CRH neurones and dete...

Effects of lateral olfactory tract stimulation on Fos immunoreactivity in vasopressin neurones of the rat piriform cortex
In the main olfactory system, odours are registered at the main olfactory epithelium and are then processed at the main olfactory bulb (MOB) and, subsequently, by the anterior olfactory nucleus (AON), the piriform cortex (PC) and the cortical amygdala. Previously, we reported populations of vasopressin neurones in different areas of the rat olfactory system, including the MOB, accessory olfactory bulb (AOB) and the AON and showed that these are involved in the coding of social odour information. Utilising immunohistochemistry and a transgenic rat in which an enhanced green fluorescent protein reporter gene is expressed in ...

Alteration in the relationship between tanycytes and gonadotrophin ‐releasing hormone neurosecretory terminals following long‐term metabolic manipulation in the sheep
The activity of the hypothalamic‐pituitary gonadal axis is influenced by energy reserves, such that an increase or a decrease in adiposity may perturb the secretion and action of gonadotrophin‐releasing hormone (GnRH). This is considered to be a result of the signalling of hormones such as leptin, which act upon neuronal systems controlling GnRH secretion. Other work shows plasticity in the relationship between tanycytes and GnRH neurosecretory terminals in the median eminence across the oestrous cycle and we hypothesised that a similar plasticity may occur with altered metabolic status. We studied Lean, Normal and Fat...

Prolactin receptors in Rip ‐cre cells, but not in AgRP neurones, are involved in energy homeostasis
Among its many functions, prolactin has been implicated in energy homeostasis, particularly during pregnancy and lactation. The arcuate nucleus is a key site in the regulation of energy balance. The present study aimed to examine whether arcuate nucleus neuronal populations involved in energy homeostasis are prolactin responsive and whether they can mediate the effects of prolactin on energy homeostasis. To determine whether Agrp neurones or Rip‐Cre neurones are prolactin responsive, transgenic mice expressing the reporter td‐tomato in Agrp neurones (td‐tomato/Agrp‐Cre) or Rip‐Cre neurones (td‐tomato/Rip‐Cre)...
