Social and neural determinants of aggressive behavior: pharmacotherapeutic targets at serotonin, dopamine and gamma-aminobutyric acid systems.
    Psychopharmacology, 2002, Volume: 163, Issue:3-4

    Aggressive outbursts that result in harm and injury present a major problem for the public health and criminal justice systems, but there are no adequate treatment options. Obstacles at the level of social policy, institutional regulation, and scientific strategy in developing animal models continue to impede the development of specific anti-aggressive agents for emergency and long-term treatments.. To be more relevant to the clinical situation, preclinical aggression research has begun to focus on the neurobiological determinants of escalated aggressive behavior that exceeds species-typical patterns. It is the goal of this review to examine novel pharmacological and molecular tools that target the neural mechanisms for different kinds of aggressive behavior more selectively than previously possible and to outline potential pharmacotherapeutic options.. (1) The preclinical focus on the behavioral characteristics and determinants of intense aggression promises to be most relevant to the clinical distinction between the proposed impulsive-reactive-hostile-affective subtypes of human aggression and the controlled-proactive-instrumental-predatory subtypes of aggression. The neural circuits for many types of human and animal aggression critically involve serotonin, dopamine and gamma-aminobutyric acid (GABA) and specific receptor subtypes. (2) The dynamic changes in frontal cortical serotonin that are triggered by engaging in aggressive behavior imply that serotonergic drug effects are largely determined by the functional state of the receptors at the time of drug treatment. Of the numerous 5-HT receptors currently identified, the 5-HT(1B) receptors offer a promising target for reducing impulsive aggressive behavior, particularly if the action can be limited to sites in the central nervous system. (3) Aggressive confrontations are salient stressors, both for the aggressor as well as the victim of aggression, that are accompanied by activation of the mesocorticolimbic but not the striatal dopamine system. Dopaminergic manipulations, particularly targeting the D(2) receptor family, can influence aggressive behavior in animals and human patients, suggesting that mesocorticolimbic dopamine may have important enabling or permissive functions. (4) GABA is critical in the neurochemical control of aggressive behavior as evidenced by studies that directly modify GABAergic neurotransmission and neurochemical studies that correlate GABA measurements with aggressive behavioral responses in several animal species. The GABA(A) receptor complex is a mechanism through which certain benzodiazepines and alcohol enhance and inhibit aggressive behaviors. Social and pharmacological experiences decisively determine the effects of GABAergic positive modulators on aggression.

Preclinical Evidence That 5-HT1B Receptor Agonists Show Promise as Medications for Psychostimulant Use Disorders.
    The international journal of neuropsychopharmacology, 2017, 08-01, Volume: 20, Issue:8

    5-HT1B receptor agonists enhance cocaine intake during daily self-administration sessions but decrease cocaine intake when tested after prolonged abstinence. We examined if 5-HT1B receptor agonists produce similar abstinence-dependent effects on methamphetamine intake.. Male rats were trained to self-administer methamphetamine (0.1 mg/kg, i.v.) on low (fixed ratio 5 and variable ratio 5) and high (progressive ratio) effort schedules of reinforcement until intake was stable. Rats were then tested for the effects of the selective 5-HT1B receptor agonist, CP 94,253 (5.6 or 10 mg/kg), or the less selective but clinically available 5-HT1B/1D receptor agonist, zolmitriptan (10 mg/kg), on methamphetamine self-administration both before and after a 21-day forced abstinence period during which the rats remained in their home cages.. The inverted U-shaped, methamphetamine dose-response function for intake on the fixed ratio 5 schedule was shifted downward by CP 94,253 both before and after abstinence. The CP 94,253-induced decrease in methamphetamine intake was replicated in rats tested on a variable ratio 5 schedule, and the 5-HT1B receptor antagonist SB 224,289 (10 mg/kg) reversed this effect. CP 94,253 also attenuated methamphetamine intake on a progressive ratio schedule both pre- and postabstinence. Similarly, zolmitriptan attenuated methamphetamine intake on a variable ratio 5 schedule both pre- and postabstinence, and the latter effect was sustained after each of 2 more treatments given every 2 to 3 days prior to daily sessions.. Unlike the abstinence-dependent effect of 5-HT1B receptor agonists on cocaine intake reported previously, both CP 94,253 and zolmitriptan decreased methamphetamine intake regardless of abstinence. These findings suggest that 5-HT1B receptor agonists may have clinical efficacy for psychostimulant use disorders.

Role of alcohol consumption in escalation to violence.
    Annals of the New York Academy of Sciences, 2004, Volume: 1036

    No other drug has been associated with aggressive and violent behavior more than alcohol has. A major characteristic of the link between alcohol and social interactions is the very large variation in who becomes more aggressive while drinking and who does not. Tracing the origins of these individual differences has led to a focus on predispositions, such as the antisocial behavior of Type 2 alcoholics. Successful development of an experimental procedure to model heightened aggressive behavior after voluntary consumption of alcohol has facilitated the neurobiologic analysis of the link between alcohol and aggression. From a pharmacologic perspective, consumption of low to moderate doses of alcohol engenders heightened aggressive behavior in a significant minority of individuals before the circulation of appreciable amounts of the aldehyde metabolite. Ionophoric receptors such as NMDA, 5-HT(3) and GABA(A) have been identified in the brain as major sites of action for alcohol in the dose range that is relevant for engendering heightened aggression. Actions at the GABA(A) receptor complex that depend on particular GABA(A) subunits appear to be necessary for alcohol-heightened aggression. Genes that encode the synthesis of these alpha and gamma subunits are potentially significant markers for those individuals that are prone to engage in heightened aggressive behavior after the consumption of alcohol. Of particular importance are the reciprocal interactions between GABA and serotonin. Activating specific serotonin receptor subtypes such as 5-HT(1B) receptors reduces alcohol-heightened aggressive behavior. How these GABAergic and serotonergic corticolimbic mechanisms for alcohol-heightened aggression develop during the adolescent period remains an area of urgent study.

Serotonergic effects and extracellular brain levels of eletriptan, zolmitriptan and sumatriptan in rat brain.
    European journal of pharmacology, 2001, Aug-17, Volume: 425, Issue:3

    In vivo microdialysis was used to assess the central serotonergic effects and extracellular brain levels of the 5-HT(1B/1D) receptor agonists eletriptan, zolmitriptan and sumatriptan in rats after intravenous and intracerebral administration, while their binding affinities and functional potencies were determined at 5-HT(1B), 5-HT(1D) and 5-HT(1A) receptors. In vitro studies showed that all three triptans are high affinity, full agonists at 5-HT(1B/1D) receptors, but that sumatriptan is functionally less potent as a 5-HT(1B/1D) agonist than zolmitriptan and eletriptan. Local intracortical perfusion with the compounds via the dialysis probe decreased cortical 5-HT (5-hydroxytryptamine, serotonin) release with ED(50) values of approximately 0.1 microM for eletriptan and zolmitriptan and 0.5 microM for sumatriptan. At 3.2 mg/kg i.v., both eletriptan and zolmitriptan decreased 5-HT levels by about 35%, while sumatriptan had no effect, despite the fact that maximal sumatriptan concentrations in cortical dialysates were higher (8.8 nM at 20 min) than those of zolmitriptan (5.9 nM at 20 min) and eletriptan (2.6 nM at 40 min). The observation that eletriptan and zolmitriptan produce almost identical central serotonergic effects, after intracerebral as well as after systemic administration, is in agreement with their comparable functional 5-HT(1B/1D) receptor agonist potencies and their free levels in cortical dialysates after 3.2 mg/kg i.v. On the other hand, the lack of central serotonergic effects of 3.2 mg/kg i.v. sumatriptan is likely due to its weaker functional 5-HT(1B/1D) receptor agonist potency than eletriptan and zolmitriptan, rather than lower brain levels, consistent with sumatriptan's fivefold lower potency after intracerebral administration.
