Aversive stimuli raise glutamate release in brain structures involved in stress-related disorders, like 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, rising NO production (Contestabile, 2000). Resulting from its higher liposolubility, NO can act presynaptically and improve neurotransmitter release (Esplugues, 2002). NO seems to become involved in stress-related disorders (Guimaraes et al., 2005), for example posttraumatic stress disorder (PTSD) (Oosthuizen et al., 2005). Many research have shown that interference with NO and glutamate signaling can attenuate the behavioral consequences of tension 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 worry conditioning, along with a marked impairment of contextual fear conditioning (CFC) (Kelley et al., 2009). This phenotype was pharmacologically 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). However, mice with deletion from the inducible NOS gene (iNOS KO) appear to become a lot more susceptible to pressure, showing anxiogenic-like behavior in the EPM (Buskila et al., 2007). Furthermore, this behavioral modify is exacerbated 7 days immediately after exposure to a predator odor (Abu-Ghanem et al., 2008). This anxiogenic-like effect was prevented by nonselective NOS inhibitor L-NAME remedy, suggesting that this behavioral alter could involve a compensatory enhance in the activity of other NOS isoforms (ie, nNOS or endothelial [eNOS]). In reality, these animals showed enhanced basal levels of NOS activity inside the amygdala and cortex, the latter impact being attenuated by inhibition of NOS constitutive isoforms (Buskila et al., 2007; Gilhotra and Dhingra, 2009). Recent results indicate that the THBS1 Protein Species nitrergic and also the endocannabinoid (ECB) systems could interact throughout stressful or aversive situations (Lisboa and Guimaraes, 2012; Lisboa et al., 2013; Lisboa et al., 2014). ECBs are lipids GAS6 Protein manufacturer synthesized from cellular membranes that behave as organic agonists for cannabinoid receptors (Battista et al., 2006; Di Marzo and Petrosino, 2007; Maccarrone et al., 2007). Similar to NO, ECBs are synthesized “on-demand” in postsynaptic neurons soon after neuronal stimulation and are not stored in vesicles, getting characterized as atypical neurotransmitters (Piomelli, 2003; Ligresti et al., 2005). After their synthesis, ECBs diffuse to presynaptic terminals where they are able to activate cannabinoid receptors type 1 (CB1) or two (CB2) and decrease the release of neurotransmitters for instance 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 suggested that CB1 rec.
