There is a large body of pre-clinical and some clinical data to link the neuropeptide galanin to a range of physiological and pathological functions that include metabolism, depression, and addiction. An enhancer region upstream of the human GAL transcriptional start site has previously been characterised. In-vitro transfection studies in rat hypothalamic neurons demonstrated that the CA allele...
Damage-induced neuronal endopeptidase (DINE) is a novel metallopeptidase and is expressed in response to various neuronal injuries. The expression regulation of DINE mRNA in the dorsal root ganglia (DRGs) after sciatic nerve injury is examined. A substantial increase of DINE mRNA expression was observed in relatively small-sized DRG neurons after nerve injury. The expression was observed in iso...
The neuropeptide galanin is predominantly expressed by the lactotrophs (the prolactin secreting cell type) in the rodent anterior pituitary and in the median eminence and paraventricular nucleus of the hypothalamus. Prolactin and galanin colocalize in the same secretory granule, the expression of both proteins is extremely sensitive to the estrogen status of the animal. The administration of es...
In the present thesis, the aim was to probe the distribution and functions of galanin type 2 receptor (GalR2) in the rodent brain. In order to overcome the lack of a reliable antibody to localize GalR2 by immunohistochemistry, we generated a construct which expresses GalR2 tagged with enhanced GFP (EGFP). We first studied the trafficking and function of this fusion protein in cell lines, includ...
The effects of corticosterone (10 mg/kg, s.c., 6 h) on dorsal raphe 5-HT1A autoreceptors have been studied in adrenalectomized rats with or without porcine galanin modulation. Adrenalectomy diminishes 5-HT1A autoreceptors affinity. Corticosterone increases 5-HT1A autoreceptor agonist affinity (+90%, p<0.001) in adrenalectomized rats. Galanin (10 nM) increases dorsal raphe 5-HT1A autoreceptor de...
The neuropeptide galanin R1 receptor (GalR1) was tagged at its C terminus with EGFP (GalR1-EGFP) to study receptor localization and trafficking. In PC12 and HEK293 cells, functional GalR1-EGFP was expressed on the plasma membrane and internalized into cytoplasmic vesicles after galanin stimulation. The internalization was blocked by 0.4 M sucrose and by silencing of clathrin with siRNA methodol...
Galanin, a neuropeptide widely expressed in the central and peripheral nervous systems and in the endocrine system, has been shown to regulate numerous physiological and pathological processes through interactions with three G-protein-coupled receptors, GalR1 through GalR3. Over the past decade, some of the receptor subtype-specific effects have been elucidated through pharmacological studies u...
