Histamine H3 receptor: a novel therapeutic target in alcohol dependence?
- Neuroscience Center, Institute of Biomedicine, Anatomy, Faculty of Medicine, University of Helsinki, Helsinki, Finland
The brain histaminergic system is one of the diffuse modulatory neurotransmitter systems which regulate neuronal activity in many brain areas. Studies on both rats and mice indicate that histamine H3 receptor antagonists decrease alcohol drinking in several models, like operant alcohol administration and drinking in the dark paradigm. Alcohol-induced place preference is also affected by these drugs. Moreover, mice lacking H3R do not drink alcohol like their wild type littermates, and they do not show alcohol-induced place preference. Although the mechanisms of these behaviors are still being investigated, we propose that H3R antagonists are promising candidates for use in human alcoholics, as these drugs are already tested for treatment of other disorders like narcolepsy and sleep disorders.
Introduction
Alcohol dependence is a remarkable health risk for the society. More than 60 diseases and injuries resulting in approximately 2.5 million deaths per year worldwide are linked to heavy alcohol drinking (Edwards et al., 2011). The number of current available medications for the treatment of alcohol dependence is limited, and most treatments show only moderate efficacy. Promising results in the treatment of alcohol dependence have been obtained with some existing drugs such as anti-epileptic drug topiramate, antispasmic baclofen, and nausea relieving ondansetrone (Sellers et al., 1994; Addolorato et al., 2002; Johnson et al., 2003). New therapeutic drug targets have also been launched during the last years including cannabinoid receptors, neuropeptide Y, corticotropin-releasing factor, and ghrelin (Kraus et al., 2005; Thorsell et al., 2006; Lowery and Thiele, 2010; Maccioni et al., 2010). Recent findings from our laboratory using various animal models assessing dependence-like alcohol behaviors as well as binge-like alcohol drinking suggest that histamine H3 receptor could be a potential therapeutic target in the treatment of alcohol dependence (Nuutinen et al., 2010, 2011a,b).
Histaminergic System Alterations Linked to High Risk Alcohol Consumption
Many modulatory neurotransmitter systems converge on the same neurons in the brain. For example, the actions of acetylcholine, histamine, norepinephrine, and serotonin on human neocortical cells are similar: they all increase spiking by reducing spike-frequency adaptation (McCormick and Williamson, 1989). It is thus not surprising that several transmitters or their respective receptor ligands can have similar effects on neural circuits and behavior. Some of the important systems in drug abuse include the mesolimbic dopamine system and corticostriatal and corticoaccumbal glutamate systems (Koob and Volkow, 2010; Kalivas and Volkow, 2011). All these brain regions are also innervated by histamine-containing nerve fibers originating from the posterior hypothalamic tuberomamillary nucleus both in rodents and in humans (Panula et al., 1989; Airaksinen et al., 1991; Jin and Panula, 2005). Following release, histamine is mainly inactivated by methylation in the brain to an inactive metabolite tele-methylhistamine, whereas in the peripheral organs oxidation by diamino-oxidase is predominant (Haas and Panula, 2003). Concentrations of tele-methylhistamine have been shown to correlate well with histamine release in the brain. Very few studies have directly analyzed the role of histamine in alcohol-related behaviors in humans, and animal studies have been carried out only recently. In postmortem analysis, histamine and tele-methylhistamine, the first metabolite of histamine, levels are clearly increased in patients who suffered from extensive liver cirrhosis following alcohol abuse (Lozeva et al., 2003). The histamine levels were elevated in both patients with high alcohol consumption and those with no alcohol use. The mechanism is thus most likely related to the highly increased levels of neutral amino acids in the blood circulation, as reviewed earlier for experimental portocaval anastomosis cases (Fogel et al., 2002). In one study on type 1 (late onset, often females, low degree of association with violence) and type 2 (early onset, often males, high degree of association with violence) alcoholics histamine levels were significantly elevated in the gray matter of type 1 alcoholics and the levels of tele-methylhistamine were elevated in type 2 alcoholics indicating that histamine turnover is altered (Alakarppa et al., 2002).
In alcohol-preferring Alko alcohol (AA) rats developed in Finland in 1960s using a two-bottle choice preference selection method (Eriksson, 1968) several aminergic systems are abnormal. They have higher tyrosine hydroxylase activity and higher levels of dopamine and noradrenaline in striatum and limbic regions (Ahtee and Eriksson, 1975), higher serotonin levels in many brain areas (Ahtee and Eriksson, 1973), and higher histamine and tele-methylhistamine levels in many brain regions than alcohol non-preferring Alko non-alcohol (ANA) rats (Lintunen et al., 2001). Higher tele-methylhistamine levels indicate also higher histamine release in AA than ANA rats. This high histamine content agrees well with the higher density of histamine-immunoreactive nerve fibers in many regions of the AA rat brain, including nucleus accumbens, septal nuclei, and medial preoptic nucleus. Thus, histamine from the other major storage site of brain histamine, mast cells, is not responsible for the significant difference. Receptor radioligand autoradiography has shown significant differences in histamine H1 receptor binding throughout the brain of AA and ANA rats. The binding densities in AA rat brain were lower, possibly as a result of high histamine release induced downregulation (Lintunen et al., 2001). H3 receptor radioligand binding is lower in AA than ANA rats in the motor cortex, nucleus accumbens, and CA1 area of the hippocampus. Although similar systematic studies have not been carried out in other rat lines selected for high volunteer alcohol intake, an analysis of histamine content in the cortex of the high alcohol preference (HAP) and low alcohol preference (LAP) rats was not different (Kitanaka et al., 2004). However, the histamine induced phosphoinositide hydrolysis was significantly lower in HAP than LAP rats (Kitanaka et al., 2004).
Rat lines selected for high alcohol sensitivity (alcohol non-tolerant, ANT) and low alcohol sensitivity (alcohol tolerant, AT; Rusi et al., 1977) also show distinct differences in histaminergic markers in the brain: the ANT rats have reduced histamine levels in many brain areas, including hypothalamus, septum, cortex, and hippocampus (Lintunen et al., 2002). The alcohol sensitive ANT rats also show higher H3 receptor agonist-induced guanosine 5′-O-(3-[35S]thio)triphosphate binding, indicative of histamine H3 receptor activation, in motor cortex, insula, and caudate-putamen (Lintunen et al., 2002). The behavioral effects of H3 receptor ligands on these rats have not been tested, but administration of a suicide inhibitor of the histamine synthesizing enzyme histidine decarboxylase, α-fluoromethylhistidine (α-FMH), decreases the performance of these rats in the tilting plane test (Lintunen et al., 2002) suggesting higher sensitivity to alcohol in the absence of histamine. Taken together, these results suggest that there are basal differences in the histamine system markers in these rat lines. However, no mutations in genes directly related to histamine synthesis and metabolism or histamine receptors have been identified.
Histamine H3 Receptor-Mediated Regulation of Alcohol Drinking
Alcohol consumption in experimental animals can be measured with different types of drinking models. One of the most widely used paradigms is the two-bottle choice test where animals are given free-choice access to alcohol and non-alcoholic fluid, typically water (Green and Grahame, 2008). Alcohol consumption in this model, however, can be influenced by other factors than pharmacological action of alcohol, such as taste and calories. Thus control studies with sweet, bitter and high caloric fluids are needed. Using a modified prolonged 8-week version of the two-bottle choice we found that the histamine H3 receptor knockout (H3R KO) mice consumed alcohol at concentrations 10 and 20% significantly less than the wild type animals (Nuutinen et al., 2011a; Table 1). Control studies with bitter quinine and sweet saccharin revealed no genotype differences. There was no difference between the H3R KO and control mice in water consumption. However, the food consumption in H3R KO mice was lower than in control animals leaving us with a question whether the H3R KO mice simply drink less alcohol since they need less energy?
Table 1. Summary of the alterations in alcohol consumption and reward followed by manipulations of the brain histaminergic system.
A more newly described method for alcohol consumption is so called Drinking in the Dark (DID) method where mice are given access to alcohol for a short period of time during their active time of the day (Rhodes et al., 2005). The DID paradigm is a measure of binge-like alcohol drinking and usually C57BL/6J mice are used in this paradigm due to their high alcohol consumption. The method is based on the finding that rodents consume more alcohol during the first couple of hours of their active period of the day (Goldstein and Kakihana, 1977). In line with the two-bottle choice (dependence-like drinking) study we found that the H3R KO mice drank less alcohol than control mice when given a 4-h access to 20% alcohol in the DID model (Nuutinen et al., 2011a; Table 1). Interestingly, H3R KO mice also consumed less 10% sucrose than the wild type mice again pointing to the direction that the lower need of calories could be the underlying reason for the lower voluntary alcohol consumption in H3R KO mice. To study this in more detail we used H3R specific ligands in the DID model and found that an H3R antagonist ciproxifan dose-dependently inhibited alcohol drinking and H3R agonist immepip increased alcohol consumption in wild type mice (Nuutinen et al., 2011a). Importantly, the consumption of 10% sucrose, very high in caloric content, was not modified by ciproxifan or immepip pretreatment suggesting that other reasons than a altered need for calories could underlie the change in alcohol consumption following modification of H3Rs. In agreement with our mouse studies, Galici et al. (2011) found that an H3R antagonist JNJ-39220675 (1 and 10 mg/kg) inhibits alcohol drinking to a similar extent as naltrexone (5 mg/kg) in a two-bottle choice test in selectively bred alcohol-preferring (P) rats. Interestingly, water consumption was increased by JNJ-39220675 treatment. JNJ-39220675 also decreased alcohol preference but not alcohol consumption after a 3-day alcohol deprivation period in P rats. These results suggest that the lack or inhibition of H3R leads to lower alcohol consumption both in mice and rats.
Alcohol drinking can be also studied using self-administration paradigms where an operant response, typically a lever press, is required for the access to drink alcohol. Self-administration models are thought to gauge better the motivation to drink alcohol (Green and Grahame, 2008). Operant alcohol self-administration using oral administration is more commonly used in rats than in mice since mice do not drink alcohol as readily as the rats do with the exception of C57BL/6J mouse strain. Already a decade ago we found that H3R antagonists thioperamide and clobenprobit (Table 2) dose-dependently (1, 3, 10 mg/kg for both drugs) decrease operant alcohol self-administration in alcohol-preferring AA rats (Lintunen et al., 2001; Table 1). Treatment with H3R agonist R-α-methylhistamine or H1R antagonist mepyramine did not affect alcohol self-administration. Recently researchers at Johnson & Johnson tested the H3R antagonist JNJ-39220675 (10 and 30 mg/kg) in an operant model and found that it significantly reduced lever presses for alcohol (Galici et al., 2011). Thus, data from oral self-administration studies support the role of H3R antagonism in suppressing motivation to drink alcohol.

Inhibitory Role of Histamine in Alcohol-Induced Conditioned Place Preference
Alcohol reward and reinforcement can be also studied using Pavlovian conditioning (Tzschentke, 2007). This approach is advisable to use in parallel with the drinking studies in order to exclude intervening variables such as anxiety (Pohorecky, 1991) or novelty seeking (Cloninger et al., 1988) that might result in altered alcohol drinking. In our laboratory, we are routinely using an unbiased alcohol-induced conditioned place preference (CPP) model in mice originally developed and described by Cunningham et al. (2006). In this model mice are given an alcohol injection paired with an environmental cue (cage floor material) for four to eight times over a period of 2–3 weeks. On alternating days with the alcohol injections mice are given vehicle injections paired with another type of floor material. After the conditioning period mice are tested in a preference test where they can choose between the two cage floor materials. Place preference is indexed by a significant difference in time spent on one of the conditioning cue floors between two groups that have had different cues when conditioned to alcohol. In mice lacking the histamine synthesizing enzyme histidine decarboxylase, the alcohol-evoked CPP was found to be stronger suggesting that the lack of histamine increases the reward and reinforcement by alcohol in mice (Nuutinen et al., 2010; Table 1). Next we used different H3R ligands and found that antagonists ciproxifan (3 mg/kg) and JNJ-10181457 (5 mg/kg) totally inhibited the CPP by alcohol in wild type DBA/2J mice (Nuutinen et al., 2011b). Importantly, H3R antagonist ciproxifan did not induce place preference or place aversion alone in 129/Sv mice suggesting that H3R antagonism does not produce place aversion or preference per se (Nuutinen et al., 2010). However, studies in other mouse strains and rats and using different H3R antagonists would be important to confirm that the H3R antagonists do not have addictive or aversive properties. The H3R agonist immepip (30 mg/kg; Table 2) did not modulate alcohol-induced CPP (Nuutinen et al., 2011b). We think that this was probably due to the difficulty to increase an already strong place preference. When CPP model was applied to H3R KO mice (C57BL/6J background), we found a complete lack of alcohol-evoked CPP (Nuutinen et al., 2011a). In agreement with the alcohol drinking studies these data suggest that inhibition or lack of H3R leads to loss of alcohol reward.
Mechanisms Underpinning the Behavioral Findings
Stronger alcohol-induced CPP in HDC KO mice suggests that histamine could be the key neurotransmitter mediating the inhibitory effects since the lack of histamine leads to stronger CPP. The inhibitory effect of H3R antagonists may, however involve other neurotransmitter systems in addition to histamine due to the heteroreceptor function of H3Rs (Schlicker et al., 1994). Interestingly, brain microdialysis studies have shown that H3R antagonists thioperamide and GSK189254 do not affect histamine release in rat nucleus accumbens or striatum, the central areas in the regulation of reward and reinforcement (Giannoni et al., 2009, 2010). Further, dopamine release seems not to be affected either in these areas. H3R antagonist ABT-239 did not modify dopamine release in striatum (Fox et al., 2005) and GSK189254 had no effect on dopamine release in nucleus accumbens (Giannoni et al., 2010; Table 2). JNJ-39220675 treatment, which was found to inhibit alcohol drinking and self-administration in rats did not change dopamine release per se or affect alcohol-induced release of dopamine (Galici et al., 2011; Tables 1 and 2). However, many of the above-mentioned drugs as well as many other H3R antagonists do increase histamine and dopamine release e.g., in prefrontal cortex (Brioni et al., 2011), another important area of the meso-cortico-limbic reward circuit which receives dopaminergic input from the ventral tegmental area and sends glutamatergic projections to striatum and nucleus accumbens (Lasseter et al., 2010). In summary, these results demonstrate that H3R antagonists affect neurotransmitter release in a region-specific manner and it seems that the inhibitory effect of H3R antagonism on alcohol consumption and CPP is likely to result from the effects of these drugs on neurotransmitter release on brain areas other than striatum and nucleus accumbens.
Another intriguing mechanism for H3R antagonist-induced inhibition of alcohol reward is the possible modulation of postsynaptic dopamine receptor signaling in striatum and nucleus accumbens. Accumulating evidence suggests that H3Rs form functional receptor heteromers with dopamine D1 and D2 receptors (Ferrada et al., 2008, 2009; Moreno et al., 2011) and that specific ligands that bind to one of the receptor of the heteromer, will affect the affinity and signaling of the other. Thus, it is possible that by binding to postsynaptic H3Rs in striatal areas, the H3R antagonists might interfere with the enhanced dopaminergic signaling induced by alcohol. We have measured the plasma alcohol concentrations after H3R ligand administration and found no difference compared to the corresponding controls thus ruling out the possibility that H3R ligands would alter alcohol metabolism (Nuutinen et al., 2011a).
Similarities and Contrasting Findings with Other Drugs of Abuse
Mechanisms leading to addictive behaviors are thought to be common for all drugs of abuse. In line with the inhibitory role of histamine in alcohol-induce place preference, a study using H1 receptor knockout mice found a stronger methamphetamine-induced CPP than in wild type controls (Takino et al., 2009) and H3R antagonists thioperamide and clobenprobit reduced amphetamine self-administration in rats (Munzar et al., 2004). In contrast to our alcohol study the CPP for methamphetamine was not different in histamine H3R KO mice compared to the control animals (Okuda et al., 2009). However, the authors used a biased CPP design (by using one conditioning cue) and place preference was scored by comparing pre-conditioning and post-conditioning times. In our laboratory we use two distinct conditioning cues that are neutral to the mice meaning that they do not prefer either one of them initially (unbiased design). This is to prevent e.g., the anxiolytic effect of the drug used that could lead to false-positive result (Cunningham et al., 2003). Further, studies have shown that mice change their preference during the conditioning period without any reinforcing drugs, so in our paradigm place preference is scored as time spent in one of the sides of the chamber during the preference test following the conditioning days (Tzschentke, 2007). We compare this time between two groups that received alcohol paired with separate cues. Significant difference between the subgroups indicates place preference.
Studies on histamine’s role in morphine dependence are few but support the inhibitory role of histamine in reward and reinforcement. Morphine-induced CPP was attenuated by increasing histamine levels with L-histidine and potentiated by inhibiting histamine synthesis with α-fluoromethyl histidine in mice (Suzuki et al., 1995; Table 2). H2 receptor antagonist zolantadine potentiated morphine-induced CPP but also induced place preference alone accompanied by an increase in dopamine turnover suggesting that it has other targets, possibly dopamine transporter, in addition to H2Rs. In accordance with our data with alcohol, the morphine-induced place preference was stronger in HDC KO mice (Gong et al., 2010).
Studies on psychostimulants (cocaine, methamphetamine) are not in line with the suggested inhibitory role of histamine in addictive behaviors. In contrast to other findings in HDC KO mice (Gong et al., 2010; Nuutinen et al., 2010), no difference in cocaine-induced CPP was found between the HDC KO and wild type mice (Brabant et al., 2007). Further, a pretreatment with an H3R antagonist thioperamide enhanced cocaine’s effects by inducing place preference in mice with a cocaine dose that did not induce CPP alone (Brabant et al., 2005). However, thioperamide was later found to inhibit cocaine metabolism via inhibition of liver CYP-450 enzymes (Brabant et al., 2009). Amphetamine is also metabolized via liver CYP-450 enzymes. Thus, the observations that H3R antagonists thioperamide and clobenpropit potentiate self-administration and discrimination of methamphetamine might be due to inhibition of methamphetamine metabolism by these imidazole-based H3R antagonists (Munzar et al., 1998, 2004). Further studies with non-imidazole-based H3R compounds and with knockout/transgenic animal models are needed to reveal the role of H3R in psychostimulant-induced reward and reinforcement.
Numerous studies on first generation H1R antagonists support the inhibitory role of histamine in reward (for a review see Brabant et al., 2010). However, these drugs have many targets in addition to H1Rs such as muscarinic receptors and more importantly, the dopamine transporter (Shishido et al., 1991; Oishi et al., 1994). Thus, it is most probably the inhibition of dopamine uptake rather than H1R blockade that explains why H1R blockers can cause per se or increase behavioral effects typically induced by addictive substances.
Conclusions
There is accumulating evidence from alcohol drinking and place preference studies suggesting that alcohol reward could be decreased by treatment with H3R antagonists. More studies are still needed to test the potential of H3R antagonists to prevent alcohol withdrawal symptoms or relapse. Cellular and molecular mechanistic studies are also of great importance in order to more widely increase our understanding of the complex role of H3R in addictive behaviors. Studies on alcohol and morphine suggest that targeting brain H3Rs could be a potential means to treat drug addiction. However, due to conflicting findings with H3R antagonists in psychostimulant addiction-related behaviors, more preclinical studies are needed to really show whether H3R antagonist would be beneficial in other types of drug addictions. One of the key questions to be solved is related to the possible differential expression of H3R in different dopaminergic neurons, and analysis of direct vs. indirect effects of H3R on dopamine release. Whereas it seems that histamine H3 receptor is a key element in alcohol drinking and place preference, the role of histamine in these behaviors is still unclear. The relative importance of histamine and other transmitters regulated by H3 receptor antagonism in several alcohol-related behaviors remains to be studied using specific tools.
