The `` non 5 HT1A ' ' sites labeled by 3H 5 HT in the presence of 0 . 1 microM 8 OH DPAT corresponded mainly to 5 HT1B sites . 5 HT1A binding was notably high in limbic regions ( dentate gyrus , CA 1 and CA 3 hippocampal regions , lateral septum , frontal cortex ) , whereas 5 HT1B binding was particularly concentrated in extrapyramidal areas ( caudate nucleus , globus pallidus , substantia nigra ) . ^^^ Except in the latter regions , where only one class of 5 HT 1 sites was found , both 5 HT1A and 5 HT1B sites existed in all areas examined . ^^^ The selective degeneration of serotoninergic neurons produced by an intracerebral injection of 5 , 7 dihydroxytryptamine was associated only with a significant loss of 5 HT1A binding to the dorsal raphe nucleus ( 60 % ) and of 5 HT1B binding to the substantia nigra ( 37 % ) . ^^^ These results are discussed in relation to the possible identity of 5 HT1A and / or 5 HT1B sites with the presynaptic 5 HT autoreceptors controlling nerve impulse flow and neurotransmitter release in serotoninergic neurons . . ^^^ |

Perfusion of serotonin ( 5 HT ; 10 microM , for 30 min at a rate of 3 microliters / min ) , dissolved in Ringer ' s solution containing 10 microM eserine , showed no marked effect on the extracellular levels of ACh . 8 Hydroxy 2 ( di n propylamino ) tetralin ( 8 OH DPAT ; 20 microM ) , a 5 HT1A agonist , increased ACh levels , whereas 7 trifluoromethyl 4 ( 4 methyl 1 piperazinyl ) pyrrolo [ 1 , 2 a ] quinoxaline ( CGS 12066B ; 100 microM ) , a 5 HT1B agonist , decreased it . ^^^ These results indicate that the 5 HT1A receptor , which exists in the dorsal hippocampus , enhances the spontaneous ACh release , and that the mechanism of serotonergic modulation of ACh release partly depends on both the stimulatory control via the 5 HT1A receptor and the suppressive one via the 5 HT1B receptor in the dorsal hippocampus of rats . . ^^^ |

In this review , the functional interactions between serotonin ( 5 HT ) and other neuronal systems are discussed with the focus on microdialysis studies in the mammalian brain ( mainly rats ) . 5 HT release is negatively regulated not only by somatodendritic 5 HT1A and terminal 5 HT1B ( 5 HT1D ) autoreceptors but also by alpha 2 adrenergic and mu opioid heteroreceptors that are located on serotonergic nerve terminals . 5 HT by itself is involved in the inhibitory effects of noradrenaline release and the facilitatory regulation of dopamine release via multiple 5 HT receptors . ^^^ |

First , our data are consistent with the primacy of 5 HT1A autoreceptors in restraining the elevation of 5 HT levels induced by SSRIs , whereas nerve terminal 5 HT1B autoreceptors appear to have an accessory role in this regard . ^^^ In particular , emerging data suggest that somatodendritic 5 HT1A autoreceptor and nerve terminal 5 HT1B autoreceptor mediated feedback may be relatively more important in the control of 5 HT output in dorsal raphe frontal cortex and median raphe dorsal hippocampus systems , respectively . ^^^ |

Role of 5 HT1A and 5 HT1B receptors in the hypophagic effect of 5 HT on the structure of feeding behavior . ^^^ In order to reveal the involvement of 5 HT1A and 5 HT1B receptors in the paraventricular nucleus of the hypothalamus ( PVN ) on serotonin induced hypophagia , we examined the effects of intra PVN injections of serotonin in WAY 100635 or SB 216641 pretreated rats on the structure of feeding behavior . ^^^ Blockade of 5 HT1A or 5 HT1B receptors in the paraventricular nucleus was effected by WAY 100635 ( 2 microg ) or SB 216641 ( 2 microg ) pretreatment ; ten minutes later , 5 HT ( 2 microg ) was applied into the same nucleus , then food intake and meal patterns were measured in a 30 minute period . ^^^ CONCLUSIONS : The hypophagic effect induced by 5 HT requires activation of 5 HT1A and 5 HT1B receptors , and the specific contribution of these subtype receptors is different , since the 5 HT1A subtype showed higher behavioral selectivity . . ^^^ |

This is made evident after administration of 5 HT ( 2A / 2C ) , and 5 HT 4 receptor agonists , or 5 HT1A , 5 HT 3 and probably 5 HT1B receptor antagonists . ^^^ A better understanding of the role played in cognition by these and other serotonin receptor subtypes is likely to result from the recent availability of highly specific ligands such as 5 HT1A , 5 HT1B , and 5 HT2A receptor antagonists , and new molecular tools such as gene knock out mice , especially inducible mice for which the genetic alteration can be restricted both temporally and anatomically . . ^^^ |

Stimulation of the lateral hypothalamus produces antinociception mediated by 5 HT1A , 5 HT1B and 5 HT 3 receptors in the rat spinal cord dorsal horn . ^^^ Intrathecal injections of the selective 5 HT1A , 5 HT1B , 5 HT 3 receptor antagonists , WAY 100135 , SB 224289 , and tropisetron , respectively , and the non specific antagonist methysergide , were given . ^^^ These results suggest that the lateral hypothalamus modifies nociception in part by activating spinally projecting serotonin neurons that act at 5 HT1A , 5 HT1B , and 5 HT 3 receptors in the dorsal horn . . ^^^ |

SB 649915 , a novel , potent 5 HT1A and 5 HT1B autoreceptor antagonist and 5 HT re uptake inhibitor in native tissue . ^^^ It has been proven that selective serotonin re uptake inhibitors are effective antidepressants but the delay to therapeutic onset of these agents is thought to be due to the time required for 5 HT1A , and possibly 5 HT1B , autoreceptor desensitisation . ^^^ Therefore an agent incorporating 5 HT re uptake inhibition coupled with 5 HT1A and / or 5 HT1B autoreceptor antagonism may provide a fast acting clinical agent . ^^^ The current studies describe the in vitro profile of SB 649915 ( 6 [ ( 1 { 2 [ ( 2 methylquinolin 5 yl ) oxy ] ethyl } piperidin 4 yl ) methyl ] 2H 1 , 4 benzoxazin 3 ( 4H ) one ) , a novel compound which has high affinity for human recombinant 5 HT1A , 5 HT1B and 5 HT1D receptors ( pKi values of 8 . 6 , 8 . 0 , 8 . 8 , respectively ) and the human recombinant 5 HT transporter ( pKi value of 9 . 3 ) . ^^^ SB 649915 also displays high affinity for rat , guinea pig , mouse and marmoset native tissue 5 HT1A , 5 HT1B and 5 HT1D receptors and rat native tissue 5 HT transporters ( pKi values > or=7 . 5 ) . ^^^ |

Selective labeling of 5 HT1A and 5 HT1B binding sites in bovine brain . ^^^ Drug interactions with serotonin ( 1A ) 5 HT1A and serotonin ( 1B ) ( 5 HT1B ) binding sites were analyzed in bovine brain membranes . 5 HT1A binding sites were directly labeled with [ 3H ] 8 hydroxy 2 ( di n propylamino ) tetralin ( 8 OH DPAT ) in bovine hippocampal membranes . 5 HT1B binding sites were labeled by [ 3H ] 5 HT in bovine striatal membranes where less than 15 % of specific binding sites are sensitive to nanomolar concentrations of 8 OH DPAT . ^^^ Each of the 12 agents tested was more potent at the 5 HT1A than 5 HT1B binding site . 5 HT , bufotenine , N , N dimethyltryptamine ( DMT ) and quipazine were only slightly more potent at the 5 HT1A binding site . ^^^ These findings suggest that 5 HT1A , and 5 HT1B binding sites have distinct pharmacological profiles and can be directly labeled with appropriate [ 3H ] ligands in specific brain regions . . ^^^ |

Perfusion of serotonin ( 5 HT ; 10 microM , for 30 min at a rate of 3 microliters / min ) , dissolved in Ringer ' s solution containing 10 microM eserine , showed no marked effect on the extracellular levels of ACh . 8 Hydroxy 2 ( di n propylamino ) tetralin ( 8 OH DPAT ; 20 microM ) , a 5 HT1A agonist , increased ACh levels , whereas 7 trifluoromethyl 4 ( 4 methyl 1 piperazinyl ) pyrrolo [ 1 , 2 a ] quinoxaline ( CGS 12066B ; 100 microM ) , a 5 HT1B agonist , decreased it . ^^^ These results indicate that the 5 HT1A receptor , which exists in the dorsal hippocampus , enhances the spontaneous ACh release , and that the mechanism of serotonergic modulation of ACh release partly depends on both the stimulatory control via the 5 HT1A receptor and the suppressive one via the 5 HT1B receptor in the dorsal hippocampus of rats . . ^^^ |

In this review , the functional interactions between serotonin ( 5 HT ) and other neuronal systems are discussed with the focus on microdialysis studies in the mammalian brain ( mainly rats ) . 5 HT release is negatively regulated not only by somatodendritic 5 HT1A and terminal 5 HT1B ( 5 HT1D ) autoreceptors but also by alpha 2 adrenergic and mu opioid heteroreceptors that are located on serotonergic nerve terminals . 5 HT by itself is involved in the inhibitory effects of noradrenaline release and the facilitatory regulation of dopamine release via multiple 5 HT receptors . ^^^ |

Differential membrane targeting and pharmacological characterization of chimeras of rat serotonin 5 HT1A and 5 HT1B receptors expressed in epithelial LLC PK 1 cells . ^^^ The serotonin 5 HT1A and 5 HT1B receptors are two structurally related but pharmacologically distinguishable 5 HT receptor types . ^^^ In brain , the 5 HT1A receptor is localized on the soma and dendrites of neurons , whereas the 5 HT1B receptor is targeted to the axon terminals . ^^^ Further investigations on the mechanisms responsible for their differential targeting were done by constructing chimeras of 5 HT1A and 5 HT1B receptors still able to bind specifically [ 3H ] lysergic acid diethylamide and selective agonists and antagonists . ^^^ Further inclusion of the C terminal domain of the 5 HT1A receptor in their sequence led to a basolateral localization , whereas that of the 5 HT1B receptor allowed an apical targeting , suggesting the existence of a targeting signal in this portion of the receptor ( s ) . . ^^^ |

Role of 5 HT1A and 5 HT1B receptors in the hypophagic effect of 5 HT on the structure of feeding behavior . ^^^ In order to reveal the involvement of 5 HT1A and 5 HT1B receptors in the paraventricular nucleus of the hypothalamus ( PVN ) on serotonin induced hypophagia , we examined the effects of intra PVN injections of serotonin in WAY 100635 or SB 216641 pretreated rats on the structure of feeding behavior . ^^^ Blockade of 5 HT1A or 5 HT1B receptors in the paraventricular nucleus was effected by WAY 100635 ( 2 microg ) or SB 216641 ( 2 microg ) pretreatment ; ten minutes later , 5 HT ( 2 microg ) was applied into the same nucleus , then food intake and meal patterns were measured in a 30 minute period . ^^^ CONCLUSIONS : The hypophagic effect induced by 5 HT requires activation of 5 HT1A and 5 HT1B receptors , and the specific contribution of these subtype receptors is different , since the 5 HT1A subtype showed higher behavioral selectivity . . ^^^ |

This is made evident after administration of 5 HT ( 2A / 2C ) , and 5 HT 4 receptor agonists , or 5 HT1A , 5 HT 3 and probably 5 HT1B receptor antagonists . ^^^ A better understanding of the role played in cognition by these and other serotonin receptor subtypes is likely to result from the recent availability of highly specific ligands such as 5 HT1A , 5 HT1B , and 5 HT2A receptor antagonists , and new molecular tools such as gene knock out mice , especially inducible mice for which the genetic alteration can be restricted both temporally and anatomically . . ^^^ |

Stimulation of the lateral hypothalamus produces antinociception mediated by 5 HT1A , 5 HT1B and 5 HT 3 receptors in the rat spinal cord dorsal horn . ^^^ Intrathecal injections of the selective 5 HT1A , 5 HT1B , 5 HT 3 receptor antagonists , WAY 100135 , SB 224289 , and tropisetron , respectively , and the non specific antagonist methysergide , were given . ^^^ These results suggest that the lateral hypothalamus modifies nociception in part by activating spinally projecting serotonin neurons that act at 5 HT1A , 5 HT1B , and 5 HT 3 receptors in the dorsal horn . . ^^^ |

SB 649915 , a novel , potent 5 HT1A and 5 HT1B autoreceptor antagonist and 5 HT re uptake inhibitor in native tissue . ^^^ It has been proven that selective serotonin re uptake inhibitors are effective antidepressants but the delay to therapeutic onset of these agents is thought to be due to the time required for 5 HT1A , and possibly 5 HT1B , autoreceptor desensitisation . ^^^ Therefore an agent incorporating 5 HT re uptake inhibition coupled with 5 HT1A and / or 5 HT1B autoreceptor antagonism may provide a fast acting clinical agent . ^^^ The current studies describe the in vitro profile of SB 649915 ( 6 [ ( 1 { 2 [ ( 2 methylquinolin 5 yl ) oxy ] ethyl } piperidin 4 yl ) methyl ] 2H 1 , 4 benzoxazin 3 ( 4H ) one ) , a novel compound which has high affinity for human recombinant 5 HT1A , 5 HT1B and 5 HT1D receptors ( pKi values of 8 . 6 , 8 . 0 , 8 . 8 , respectively ) and the human recombinant 5 HT transporter ( pKi value of 9 . 3 ) . ^^^ SB 649915 also displays high affinity for rat , guinea pig , mouse and marmoset native tissue 5 HT1A , 5 HT1B and 5 HT1D receptors and rat native tissue 5 HT transporters ( pKi values > or=7 . 5 ) . ^^^ |
