Endocannabinoids (eCBs) are natural lipids regulating a large array of physiological functions and behaviors in vertebrates. The eCB system is highly conserved in evolution and comprises several specific receptors (type-1 and type-2 cannabinoid receptors), their endogenous ligands (e.g., anandamide and 2-arachidonoylglycerol), and a number of biosy...
Chapter
This chapter will start by reviewing the fundamental features of adultneurogenesis in vertebrates. Noteworthy, the number of proliferationzones in the adult brain is strongly reduced in the transition between fishand tetrapods and even more in mammals compared to non-mammalianvertebrates. Although the functional meaning of this restriction is still...

A number of studies have separately shown that the neuregulin1 (NRG1)/ErbB4 system and NMDA-type glutamate receptors (NMDARs) are involved in several aspects of neuronal migration. In addition, intracellular calcium fluctuations play central roles in neuronal motility. Stable expression of the tyrosine kinase receptor ErbB4 promotes migratory activ...
Article
Alternative splicing of the metabotropic glutamate receptor 1 (mGluR1) receptor gene generates two major receptor isoforms, mGluR1a and mGluR1b, differing in intracellular function and distribution. However, little is known on the expression profiles of these variants during development. We examined the mRNA expression profile of mGluR1a/b in micro...
Article
Methamphetamine produces locomotor activation and typical stereotyped motor patterns, which are commonly related with increased catecholamine activity within the basal ganglia, including the dorsal and ventral striatum. Since the cerebellum is critical for movement control, and for learning of motor patterns, we hypothesized that cerebellar catecho...

New cells are continuously added to the rodent olfactory bulb (OB), throughout development and in adults. These cells migrate tangentially from the subventricular zone along the rostral migratory stream to the OB, where they migrate radically from the center to periphery of the OB. Although different modalities of radial migration have been describ...
Article
In the rodent brain neural progenitor cells are born in the subventricular zone and migrate along a pathway called the rostral migratory stream (RMS) into the olfactory bulb where they differentiate into several classes of interneurones. In the adult, tangential migration in the RMS takes place in 'chains' of cells contained within glial tubes. In...
Article
Neuregulins (NRGs), and their cognate receptors (ErbBs), play essential roles in numerous aspects of neural development and adult synaptic plasticity. The goal of this study was to investigate the developmental expression profiles of these molecules during the olfactory bulb (OB) maturation. The OB is a highly organized structure with cell types an...
Article
The interplay between neuregulins and the ErbB receptor family has a pivotal role in the development of several tissues, including the nervous system, and is maintained in the adult olfactory system where extensive plasticity and neurogenesis are retained. In the present work we show the immunohistochemical localization of ErbB-3 and ErbB-4 in the...
Article
Olfactory bulb interneurons are continuously generated throughout development and in adulthood. These neurons are born in the subventricular zone (SVZ) and migrate along the rostral migratory stream into the olfactory bulb where they differentiate into local interneurons. To investigate the differentiation of GABAergic interneurons of the olfactory...
Article
ErbB-4 is expressed by the periglomerular and the mitral/tufted cells of the adult mouse olfactory bulb (OB) and in the present work we tested whether this expression is regulated by the olfactory nerve input to the OB. Reversible zinc sulphate lesions of the olfactory mucosa were made in adult mice and the deafferented OB analysed by immunohistoch...
Article
Previously, we have shown that erbB-3 expression is restricted to the ensheathing cells of the olfactory nerve layer, while erbB-4 is found in the periglomerular and mitral/tufted cells of the olfactory bulb and in cells coming out from the rostral migratory stream of the subependymal layer. In the present work, we have treated adult mice with zinc...
Article
The present study has analyzed the effect of progesterone and its derivatives (dihydroprogesterone and tetrahydroprogesterone) on the gene expression of the peripheral myelin protein 22 utilizing in vivo and in vitro models. The data obtained indicate that tetrahydroprogesterone is able to stimulate the gene expression of peripheral myelin protein...
