“…Here, we demonstrate that the transmitters involved in this paracrine nonsynaptic mode of communication may be responsible of the modulation of neuronal migration, thus confirming that paracrine transmitters influence brain construction. This study shed new light on the results of the numerous studies investigating the modulatory role played by the transmitters during CNS development (Komuro and Rakic, 1993;Behar et al, 1998Behar et al, , 1999Behar et al, , 2000Behar et al, , 2001Fueshko et al, 1998;Hirai et al, 1999;Bless et al, 2000;Simonian and Herbison, 2001;Kihara et al, 2002;Lopez-Bendito et al, 2003). As suggested by Owens and Kriegstein (2002), one could hypothesize that the modulation of neuronal migration by transmitters in those previous studies might be mediated exclusively by a nonvesicular release.…”

“…Indeed, several studies that focused on various brain structures (cerebellar cortex, cerebral cortex, olfactory epithelium, basal forebrain) and neuronal subtypes (granule cells, cortical neuroblasts, tangentially migrating interneurons, luteinizing hormonereleasing hormone neuroblasts, gonadotropin-releasing hormone neuroblasts) have been performed using different protocols (dissociated cells in microchemotaxis chambers, slice preparation). These studies have led to the conclusion that transmitters, GABA and glutamate, acting on several receptor subtypes (GABA A , GABA B , GABA C , NMDA, AMPA) have a crucial modulatory effect on migrating neuroblasts, acting as motility-promoting signals (Behar et al, 1998(Behar et al, , 1999(Behar et al, , 2000(Behar et al, , 2001Hirai et al, 1999;Simonian and Herbison, 2001;Lopez-Bendito et al, 2003), acceleratory signals (Komuro and Rakic, 1993), or stop signals (Behar et al, 1998(Behar et al, , 2000Fueshko et al, 1998;Bless et al, 2000;Simonian and Herbison, 2001;Kihara et al, 2002). However, in contrast to these observations, there is no deficit in cortical layering and synapse formation in mice in which vesicular release has been deleted: munc18-1 mutant mice (Verhage et al, 2000) or munc13-1/2 double knock-out (KO) mice (Varoqueaux et al, 2002).…”

“…In addition, activation of NMDAR decreases basal actin polymerization state and TGF-␤1-induced actin reorganization in HK-2. The effect of NMDAR activation and Ca 2ϩ on cell migration 19,20 and actin organization 26,27 has previously been reported in different cell types. Nahm et al 20 showed that Ca 2ϩ entry through activated NMDAR inhibited keratinocyte outgrowth and migration.…”

“…Nahm et al 20 showed that Ca 2ϩ entry through activated NMDAR inhibited keratinocyte outgrowth and migration. Kihara et al 19 reported that stimulation of NMDAR inhibited neuronal migration in embryonic rat cerebral cortex. Furthermore, Cristofanilli and Akopian 27 showed that the NMDAR activation and influx of Ca 2ϩ caused a reduction of F-actin in retinal neurons of salamander, whereas NMDAR activation in rat cerebellar granule cells rapidly shifted F/G-actin equilibrium in favor of depolymerization.…”
