Aversive stimuli enhance glutamate release in brain structures involved in stress-related issues, for example the medial prefrontal cortex (MPFC), amygdala, hippocampus (HIP), and dorsal periaqueductal gray matter (Moghaddam, 1993; Musazzi et al., 2011; Riaza Bermudo-Soriano et al., 2012). Glutamate, by acting on NMDA receptors and rising calcium influx, can activate the neuronal nitric oxide synthase (nNOS) enzyme, escalating NO production (Contestabile, 2000). As a consequence of its high liposolubility, NO can act presynaptically and raise neurotransmitter release (Esplugues, 2002). NO seems to become involved in stress-related problems (Guimaraes et al., 2005), for instance posttraumatic anxiety disorder (PTSD) (Oosthuizen et al., 2005). Quite a few research have shown that interference with NO and glutamate signaling can attenuate the behavioral consequences of pressure exposure in rodents (Forestiero et al., 2006; Joca and Guimaraes, 2006; Spolidorio et al., 2007; Resstel et al., 2008; Aguiar and Guimaraes, 2009; Tonetto et al., 2009; Lisboa, 2011, 2013; ). Supporting NO involvement in anxiousness, nNOS knockout (KO) mice present anxiolytic-like behavior inside the elevated plus maze (EPM) test (Wultsch et al., 2007), decreased auditory fear conditioning, as well as a marked impairment of contextual worry conditioning (CFC) (Kelley et al., 2009). This phenotype was pharmacologically CD200 Protein Gene ID mimicked by administration of preferential nNOS inhibitors to wild-type (WT) mice or rescued by an NO donor in nNOS KO mice (Kelley et al., 2010). Alternatively, mice with deletion with the inducible NOS gene (iNOS KO) seem to be a lot more susceptible to strain, displaying anxiogenic-like behavior within the EPM (Buskila et al., 2007). In addition, this behavioral change is exacerbated 7 days following exposure to a predator odor (Abu-Ghanem et al., 2008). This anxiogenic-like effect was prevented by nonselective NOS inhibitor L-NAME therapy, suggesting that this behavioral modify could involve a compensatory boost within the activity of other NOS isoforms (ie, nNOS or endothelial [eNOS]). The truth is, these animals showed elevated basal levels of NOS activity within the amygdala and cortex, the latter impact getting attenuated by inhibition of NOS constitutive isoforms (Buskila et al., 2007; Gilhotra and Dhingra, 2009). Recent outcomes indicate that the nitrergic along with the endocannabinoid (ECB) systems could interact in the course of stressful or aversive scenarios (Lisboa and Guimaraes, 2012; Lisboa et al., 2013; Lisboa et al., 2014). ECBs are lipids synthesized from cellular membranes that behave as all-natural agonists for cannabinoid receptors (Battista et al., 2006; Di Marzo and Petrosino, 2007; Maccarrone et al., 2007). Related to NO, ECBs are synthesized “on-demand” in postsynaptic neurons right after neuronal stimulation and are not stored in vesicles, being characterized as atypical neurotransmitters (LAIR1 Protein custom synthesis Piomelli, 2003; Ligresti et al., 2005). Immediately after their synthesis, ECBs diffuse to presynaptic terminals where they will activate cannabinoid receptors variety 1 (CB1) or 2 (CB2) and lower the release of neurotransmitters which include glutamate and GABA (Wilson and Nicoll, 2002; De Petrocellis et al., 2004; Fernandez-Ruiz et al., 2007, 2008). ECBs are metabolized postsynaptically by the enzymes fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL). It has been recommended that CB1 rec.
