Abstract
Based on multivariate statistics, this review compared major triacylglycerols (TAGs) in animal milk and human milk fat from China and other countries. Human milk fat differs from animal milk fat in that it has longer acyl chains and higher concentrations of 1,3-dioleoyl-2-palmitoyl-glycerol (O-P-O) and 1-oleoyl-2-palmitoyl-3-linoleoylglycerol (O-P-L). O-P-L is a significant and distinct TAG in human milk fat, particularly in China. 1-oleoyl-2-palmitoyl-3-linoleoylglycerol (OPL) is human milk's major triglyceride molecule of O-P-L, accounting for more than 70%. As a result, OPL has piqued the interest of Chinese academics. The synthesis process and nutritional outcomes of OPL have been studied, including changes in gut microbiota, serum lipid composition, improved fatty acid and calcium absorption, and increased total bile acid levels. However, current OPL research is limited. Therefore, this review discussed enzymatic preparation of 1,3-dioleoyl-2-palmitoyl-glycerol (OPO) and OPL and their nutritional and physiological activity to direct future research direction for sn-2 palmitate and OPL.

Abstract
Adenosine 5'-monophosphate-activated protein kinase (AMPK) is an evolutionarily conserved serine/threonine kinase involved in the homeostasis of cellular energy. AMPK has developed as an appealing clinical target for the diagnosis of multiple metabolic diseases such as diabetes mellitus, obesity, inflammation, and cancer. Genetic and pharmacological studies indicate that AMPK is needed in response to glucose deficiency, dietary restriction, and increased physical activity for preserving glucose homeostasis. After activation, AMPK influences metabolic mechanisms contributing to enhanced ATP production, thus growing processes that absorb ATP simultaneously. In this review, several natural products have been discussed which enhance the sensitivity of AMPK and alleviate sub complications or different pathways by which such AMPK triggers can be addressed. AMPK Natural products as potential AMPK activators can be developed as alternate pharmacological intervention to reverse metabolic disorders including type 2 diabetes.

Neuroprotective Efficacy of Edaravone against Arsenic-Induced Behavioral and Neurochemical Deficits in Rats: Amelioration of Cholinergic and Mitochondrial Functions. CNS & NEUROLOGICAL DISORDERS DRUG TARGETS 2023; 22:125-136.

Abstract
BACKGROUND A substantial amount of evidence indicates that long-term arsenic exposure leads to various types of pathological complications, especially cognitive dysfunction. OBJECTIVE The present study was designed to assess the neuroprotective potential of edaravone (a potent free radical scavenger) against arsenic-induced neurotoxicity in Wistar rats. METHODS Adult male Wistar rats were randomly divided into five groups. Arsenic (20 mg/kg/day; p.o.) and Edaravone (5 and 10 mg/kg/day; i.p.) were administered in different experimental groups for 28 days. RESULTS The results of various behavioral test paradigms revealed that arsenic caused significant learning and memory deficits, along with anxiety-like behavior. In biochemical analysis, we found marked elevations of oxidative-nitrosative stress (indicated by augmentation of lipid peroxidation and nitrite) and a reduction of glutathione levels in the hippocampus and frontal cortex region of arsenictreated rats. Moreover, arsenic administration caused mitochondrial complexes impairment and reduction of acetylcholinesterase level. On the other hand, chronic treatment with edaravone (10 mg/kg) significantly ameliorated the arsenic-induced behavioral deficits and neurochemical anomalies. CONCLUSION This study suggests that edaravone confers neuroprotection against arsenic-induced memory impairment and anxiety-like behavior, which may be attributed to the inhibition of oxidativenitrosative stress and amelioration of cholinergic and mitochondrial functions.

Abstract
Depression is a very common mental disorder and mechanism that is associated with mitochondrial dysfunction. In the present study, we examined the mechanisms of action of isolated brain mitochondria in rats with depression for the first time. This will help identify the mitochondrial protective pathways of the two drugs and shed light on new therapeutic goals for developing antidepressants. Forced swimming, tail suspension, and sucrose preference tests were used to assess depressive-like behaviors and the oxidative stress factors of brain tissue, and measure the gene expression of apoptotic and anti-apoptotic, neuroplasticity, and neuroinflammatory factors by RT-PCR and acetylcholinesterase (AChE) activity in brain tissue (hippocampus and prefrontal) and the serum levels of corticosterone and fasting blood sugar. The results showed that the separation of neonatal rats from their mothers induced depressive-like behaviors, weight loss, mitochondrial dysfunction, increased expression of genes involved in neuroinflammation, apoptosis, genes involved in the depressive process, and decreased expression of genes involved in mood in both the hippocampus and prefrontal cortex. Maternal separation increased serum corticosterone levels, caused dysfunction of the cholinergic system, and also increased AChE activity. Treatment with different concentrations of minocycline and edaravone (1, 20, and 50 mg/kg), 5MTHF, and citalopram for 14 days showed that these drugs improved depression-like behaviors and mitochondrial function. It also reduced the expression of genes involved in neuroinflammation, apoptosis, and depression and increased the expression of genes involved in mood. In conclusion, minocycline and edaravone have neuroprotective, mitochondrial protective, antioxidant, anti-inflammatory, and anti-apoptotic effects against depressive-like behaviors caused by chronic stress.

Abstract
Different infant diets have strong effects on child development and may engender variations in fecal microbiota and metabolites. The objective of this study was to evaluate the effect of an infant formula containing sn-2 palmitate on fecal microbiota and metabolites in healthy term infants. The study involved three groups as indicated below. Investigational: the group fed a formula containing high sn-2 palmitate for 16 weeks. Control: the group fed a formula using a regular vegetable oil for 16 weeks. Breastfed: the group fed breast milk for 16 weeks. Fecal samples were collected at 8 weeks (n = 35, 37, and 35, respectively) and 16 weeks (n = 30, 32, and 30, respectively) for the control, investigational, and breastfed infants. Microbiota data were obtained using 16S rRNA sequencing. Short-chain fatty acid (SCFA) analysis was performed using GC-MS, and untargeted metabolomics was conducted using LC-MS. The effect of the formula containing sn-2 palmitate was different from that of the control formula on microbiota and metabolites. Sn-2 palmitate promoted the proliferation of Bifidobacterium and reduced the abundance of Escherichia-Shigella at 8 weeks. Furthermore, it increased α-diversity and enhanced acetate content in feces at both 8 and 16 weeks. In the investigational group infants, the abundance of DL-tryptophan, indole-3-acrylic acid, acetyl-β-methylcholine, L-methionine, and 2-hydroxyvaleric acid significantly increased at 8 weeks, while a notable increase in the abundance of 3-phenyllactic acid, palmitic acid, L-phenylalanine, and leucylproline was observed at 16 weeks. In addition, compared with that of the control infants, the intestinal microbiota and metabolites of sn-2 palmitate-supplemented infants were more similar to those of the breastfed infants. The study hopes to provide a scientific basis for the development of functional infant formulas in the future.

Abstract
Neuropathic pain is a maladaptive pain phenotype that results from injury or damage to the somatosensory nervous system and is proposed to be linked to a cascade of events including excitotoxicity, oxidative stress, mitochondrial dysfunction, neuroinflammation and apoptosis. Oxidative/nitrosative stress is a critical link between neuroinflammation and neurodegeneration through poly (ADP) ribose polymerase (PARP) overactivation. Hence, the present study investigated the antioxidant and anti-inflammatory effects of peroxynitrite decomposition catalyst; FeTMPyP in chronic constriction injury (CCI) of sciatic nerve-induced neuropathy in rats. CCI of the sciatic nerve manifested significant deficits in behavioral, biochemical, functional parameters and was markedly reversed by administration of FeTMPyP. After 14 days of CCI induction, oxidative/nitrosative stress and inflammatory markers such as iNOS, NF-kB, TNF-α and IL-6 were elevated in sciatic nerves of CCI rats along with depleted levels of ATP and elevated levels of poly (ADP) ribose (PAR) in both sciatic nerves in ipsilateral (L4-L5) dorsal root ganglions (DRG's), suggesting over activation of PARP. Additionally, CCI resulted in aberrations in mitochondrial function as evident by decreased Mn-SOD levels and respiratory complex activities with increased mitochondrial fission protein DRP-1. These changes were reversed by treatment with FeTMPyP (1 & 3 mg/kg, p.o.). Findings of this study suggest that FeTMPyP, by virtue of its antioxidant properties, reduced both PARP over-activation and subsequent neuroinflammation resulted in protection against CCI-induced functional, behavioral and biochemical deficits.

Abstract
Insulin deficiency or resistance can promote dementia and hallmarks of Alzheimer's disease (AD). The formation of neurofibrillary tangles of p-TAU protein, extracellular Aβ plaques, and neuronal loss is related to the switching off insulin signaling in cognition brain areas. Metformin is a biguanide antihyperglycemic drug used worldwide for the treatment of type 2 diabetes. Some studies have demonstrated that metformin exerts neuroprotective, anti-inflammatory, anti-oxidant, and nootropic effects. This study aimed to evaluate metformin's effects on long-term memory and p-Tau and amyloid β modulation, which are hallmarks of AD in diabetic mice. Swiss Webster mice were distributed in the following experimental groups: control; treated with streptozotocin (STZ) that is an agent toxic to the insulin-producing beta cells; STZ + metformin 200 mg/kg (M200). STZ mice showed significant augmentation of time spent to reach the target box in the Barnes maze, while M200 mice showed a significant time reduction. Moreover, the M200 group showed reduced GFAP immunoreactivity in hippocampal dentate gyrus and CA1 compared with the STZ group. STZ mice showed high p-Tau levels, reduced p-CREB, and accumulation of β-amyloid (Aβ) plaque in hippocampal areas and corpus callosum. In contrast, all these changes were reversed in the M200 group. Protein expressions of p-Tau, p-ERK, pGSK3, iNOS, nNOS, PARP, Cytochrome c, caspase 3, and GluN2A were increased in the parietal cortex of STZ mice and significantly counteracted in M200 mice. Moreover, M200 mice also showed significantly high levels of eNOS, AMPK, and p-AKT expression. In conclusion, metformin improved spatial memory in diabetic mice, which can be associated with reducing p-Tau and β-amyloid (Aβ) plaque load and inhibition of neuronal death.

Antioxidants (Basel) 2020; 9:antiox9060467. [PMID: 32492872 PMCID: PMC7346179 DOI: 10.3390/antiox9060467] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Revised: 05/22/2020] [Accepted: 05/22/2020] [Indexed: 01/01/2023] Open
Abstract
Mn(III) meso-tetrakis(N-n-hexylpyridinium-2-yl)porphyrin, (H2O)MnTnHex-2-PyP5+ (MnHex) carrying long hexyl chains, is a lipophilic mimic of superoxide dismutase (SOD) and a redox-active drug candidate. MnHex crosses the blood–brain barrier, and improved neurologic outcome and decreased infarct size and inflammation in a rat middle cerebral artery occlusion (MCAO) ischemic stroke model. Yet, the dose and the therapeutic efficacy of Mn porphyrin were limited by an adverse effect of arterial hypotension. An equally lipophilic Fe analog, (OH)FeTnHex-2-PyP4+ (FeHex), is as redox-active and potent SOD mimic in vitro. With different coordination geometry of the metal site, FeHex has one hydroxo (OH) ligand (instead of water) bound to the Fe center in the axial position. It has ~2 orders of magnitude higher efficacy than MnHex in an SOD-deficient E. coli model of oxidative stress. In vivo, it does not cause arterial hypotension and is less toxic to mice. We thus evaluated FeHex versus MnHex in a rodent MCAO model. We first performed short- and long-term pharmacokinetics (PK) of both porphyrins in the plasma, brain, and liver of rats and mice. Given that damage to the brain during stroke occurs very rapidly, fast delivery of a sufficient dose of drug is important. Therefore, we aimed to demonstrate if, and how fast after reperfusion, Fe porphyrin reaches the brain relative to the Mn analog. A markedly different plasma half-life was found with FeHex (~23 h) than with MnHex (~1.4 h), which resulted in a more than 2-fold higher plasma exposure (AUC) in a 7-day twice-daily treatment of rats. The increased plasma half-life is explained by the much lower liver retention of FeHex than typically found in Mn analogs. In the brain, a 3-day mouse PK study showed similar levels of MnHex and FeHex. The same result was obtained in a 7-day rat PK study, despite the higher plasma exposure of FeHex. Importantly, in a short-term PK study with treatment starting 2 h post MCAO, both Fe- and Mn- analogs distributed at a higher level to the injured brain hemisphere, with a more pronounced effect observed with FeHex. While a 3-day mouse MCAO study suggested the efficacy of Fe porphyrin, in a 7-day rat MCAO study, Mn-, but not Fe porphyrin, was efficacious. The observed lack of FeHex efficacy was discussed in terms of significant differences in the chemistry of Fe vs. the Mn center of metalloporphyrin; relative to MnHex, FeHex has the propensity for axial coordination, which in vivo would preclude the reactivity of the Fe center towards small reactive species.

Abstract
BACKGROUND Pharmacological inhibition of soluble epoxide hydrolase (sEH) enhances the synaptic function in the CNS and has a protective role in cognitive decline. We hypothesized that the sEH inhibitor TPPU might prevent the diabetes-induced decline in learning and memory which is associated with an alteration in the level of neurotransmitters and oxidative stress. METHODS Type 1 diabetes was induced in rats and the animals were treated with TPPU for 8 weeks. The learning and memory functions were assessed by the Barnes maze and a step-down test. Indicators of oxidative stress, levels of neurotransmitters, and activity of acetylcholinesterase were measured in the discrete regions of the brain. RESULTS Our results revealed that treatment with TPPU significantly improves learning and memory performance in diabetic rats along with decreasing the level of blood sugar. Moreover, treatment with TPPU significantly prevented the diabetes-induced alteration in levels of neurotransmitters, the activity of acetylcholinesterase and preserved anti-oxidant defence system. CONCLUSION Inhibition of the sEH alleviates diabetes-induced decline in learning and memory.

Abstract
This study investigated the effect of Aloe vera in diabetes-induced nephropathy in rats. As diabetes-associated hyperlipidemia and oxidative stress have been implicated in the pathogenesis of diabetic nephropathy, we evaluated the protective effect of whole leaf extract of Aloe vera on the basis of its hypolipidemic and antioxidative property. Aloe vera (300 mg/kg orally) has been noted to possess renoprotective effect in experimental diabetic nephropathy. However, its mechanism is not fully understood. Rats were administered streptozotocin (STZ) (55 mg/kg intraperitoneally once) to induce experimental diabetes mellitus. The development of diabetic nephropathy was assessed biochemically and histologically. In addition, the diabetes-induced lipid profile and renal oxidative stress were assessed. The single administration of STZ produced diabetes, which induced renal oxidative stress, altered the lipid profile, and subsequently produced nephropathy in eight weeks by increasing serum creatinine, blood urea nitrogen, proteinuria, and glomerular damage. Treatment with Aloe vera (300 mg/kg/day orally) was noted to be more effective against the diabetes-induced nephropathy and renal oxidative stress as compared to lisinopril (1 mg/kg/day orally), a reference agent. It may be concluded that diabetes-induced oxidative stress and lipid alterations may be accountable for the induction of nephropathy in diabetic rats. The treatment with Aloe vera (300 mg/kg/day orally) may have prevented the development of diabetes-induced nephropathy by reducing lipid alteration, decreasing renal oxidative stress, and providing direct renoprotective action.

Abstract
Several studies reported that stress can enhance the consumption of alcohol in humans and animals. However, the combinatorial effect of stress and alcohol on cognitive function and neurochemical alterations is quite understudied. In the present study, we have elucidated the involvement of oxidative stress-PARP cascade in alcohol and restraint stress (RS)-exposed animals using a PARP inhibitor, 1,5-isoquinolinediol (3mg/kg for 14days). Male Swiss albino mice were given alcohol (ALC) or RS (2h per day) or both in ALC+RS group for 28days. Behavioral analysis revealed cognitive dysfunction in ALC+RS group. Furthermore, oxidative stress and raised level of pro-inflammatory cytokines were found in the hippocampus region of ALC+RS group. Semi-quantitative reverse transcriptase PCR showed overactivation of PARP-1 gene in ALC+RS group. 1,5-isoquinolinediol treatment significantly prevented cognitive deficits and aforementioned neurochemical alterations. Overall, our findings showed that ALC+RS exerted deleterious effects on the hippocampus which involves oxidative stress-PARP overactivation cascade.

Abstract
Cisplatin is a chemotherapeutic agent used in the treatment of malignant tumors. A major clinical limitation of cisplatin is its potential toxic effects, including neurotoxicity. Edaravone, a potent free radical scavenger, has been reported to have the neuroprotective effect against neurological deficits. The aim of the present study was to determine the neuroprotective effect of edaravone against cisplatin-induced behavioral and biochemical anomalies in male Wistar rats. Our results showed that cisplatin (5mg/kg/week, i.p.) administration for seven weeks caused marked cognitive deficits and motor incoordination in rats. This was accompanied by oxido-nitrosative stress, neuroinflammation, NF-κB activation and down-regulation of Nrf2/HO-1 gene expression level in the hippocampus. Edaravone (10mg/kg/week, i.p.) treatment for seven weeks inhibited the aforementioned neurobehavioral and neurochemical deficits. Furthermore, edaravone was found to up-regulate the gene expression level of Nrf2/HO-1 and prevented the cisplatin-induced NF-κB activation. These findings demonstrated that oxido-nitrosative stress and inflammatory signaling mediators play a key role in the development of cisplatin-induced neurobehavioral deficits which were prevented by edaravone treatment.

PARP inhibition attenuates neuroinflammation and oxidative stress in chronic constriction injury induced peripheral neuropathy. Life Sci 2016; 150:50-60. [PMID: 26921631 DOI: 10.1016/j.lfs.2016.02.085] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2015] [Revised: 02/12/2016] [Accepted: 02/23/2016] [Indexed: 12/20/2022]
Abstract
AIM Peripheral nerve degeneration after nerve injury is accompanied with oxidative stress that may activate poly ADP-ribose polymerase (PARP, DNA repair enzyme). PARP overactivation amplifies the neuronal damage either due to energy crisis or through inflammatory process by facilitating nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB). Hence investigated the role of PARP inhibitors, 3-Aminobenzamide (3-AB) and 1,5-isoquinolinediol (ISO) in the attenuation of chronic constriction injury (CCI) induced peripheral neuropathy in rats. METHODS 3-AB and ISO (at doses 30 and 3mg/kg i.p., respectively) were tested in rats subjected to standard tests for evaluating hyperalgesia and allodynia. Sciatic functional index (SFI) was assessed by performing walking track analysis. Oxidative stress and inflammation induced biochemical alterations were estimated after 14 days in sciatic nerve and lumbar spinal cord. Molecular changes were explored by immunohistochemistry and DNA fragmentation by TUNEL assay. KEY FINDINGS Treatment significantly improved sensorimotor responses (p<0.001), SFI (p<0.001) and foot posture. PARP inhibition significantly (p<0.01 and p<0.001) reduced the elevated levels of nitrite, inflammatory markers and also normalized the depleted NAD(total) levels. The protein expression of poly (ADP-ribose) (PAR), NF-κB, cyclooxygenase-2 (COX-2) and nitrotyrosine were significantly (p<0.01 and p<0.001) decreased in both sciatic nerve and lumbar spinal cord, evident through immunohistochemistry. SIGNIFICANCE Present study outcomes fortify the pathological role of PARP overactivation in CCI induced neuropathy and PARP inhibition ameliorated oxidative stress and neuroinflammation associated with CCI induced nerve injury. Therefore, the current study suggests the PARP inhibitors can further be evaluated for designing futuristic strategies for the management of trauma induced neuropathy.

Abstract
Mounting evidence suggests that long-term aluminum exposure results in severe toxic effects, including neurobehavioral and neurochemical anomalies. The present study was performed to examine the neuroprotective potential of hesperidin and silibinin against aluminum chloride (AlCl3)-induced neurotoxicity in mice. AlCl3 (100 mg/kg/day) was injected daily through oral gavage for 42 days. Concomitantly, hesperidin (50 and 100 mg/kg/day, p.o.) and silibinin (100 and 200 mg/kg/day, p.o.) was administered for 42 days in different groups. The extent of cognitive impairment was assessed by Morris water maze and novel object recognition test on the 43rd day. Neurotoxicity was assessed by measuring oxido-nitrosative stress and proinflammatory cytokines in the hippocampus of mice. Six weeks treatment with AlCl3 caused cognitive impairment as indicated by an increase in the retention latency time and reduction in the percentage of recognition index. AlCl3-treated group showed oxido-nitrosative stress as indicated by increase in the level of lipid peroxidation, nitrite and depleted reduced glutathione, catalase activity in the hippocampus. Moreover, the chronic AlCl3 administration raised the proinflammatory cytokines (interleukin-1β and tumor necrosis factor-α) level and increased acetylcholinesterase activity and reduced the BDNF content in the hippocampus of AlCl3-treated animals. However, chronic treatment with hesperidin and silibinin at higher doses significantly ameliorated the AlCl3-induced cognitive impairment and hippocampal biochemical anomalies. The present study clearly indicated that hesperidin and silibinin exert neuroprotective effects against AlCl3-induced cognitive impairment and neurochemical changes. Amelioration of cognitive impairment may be attributed to the impediment of oxido-nitrosative stress and inflammation in the hippocampus.

Abstract
Poly(ADP-ribose) polymerase-1 (PARP-1) is a DNA nick-sensor enzyme that functions at the center of cellular stress response and affects the immune system at several key points, and thus modulates inflammatory diseases. Our previous study demonstrated that lipopolysaccharide (LPS)-induced depressive-like behavior in mice can be ameliorated by 3-aminobenzamide, which is a PARP-1 inhibitor. In the present study we've examined the effect of a free radical scavenger, edaravone pretreatment against LPS-induced anxiety and depressive-like behavior as well as various hippocampal biochemical parameters including PARP-1. Male Swiss albino mice were treated with edaravone (3 & 10mg/kgi.p.) once daily for 14days. On the 14th day 30min after edaravone treatment mice were challenged with LPS (1mg/kgi.p.). After 3h and 24h of LPS administration we've tested mice for anxiety and depressive-like behaviors respectively. Western blotting analysis of PARP-1 in hippocampus was carried out after 12h of LPS administration. Moreover, after 24h of LPS administration serum corticosterone, hippocampal BDNF, oxido-nitrosative stress and pro-inflammatory cytokines were estimated by ELISA. Results showed that pretreatment of edaravone (10mg/kg) ameliorates LPS-induced anxiety and depressive-like behavior. Western blotting analysis showed that LPS-induced anomalous expression of PARP-1 significantly reverses by the pretreatment of edaravone (10mg/kg). Biochemical analyses revealed that LPS significantly diminishes BDNF, increases pro-inflammatory cytokines and oxido-nitrosative stress in the hippocampus. However, pretreatment with edaravone (10mg/kg) prominently reversed all these biochemical alterations. Our study emphasized that edaravone pretreatment prevents LPS-induced anxiety and depressive-like behavior, mainly by impeding the inflammation, oxido-nitrosative stress and PARP-1 overexpression.

Abstract
Poly (ADP-ribose) polymerase-1 (PARP-1) functions at the center of cellular stress and sways the immune system at several key points, thus modulates inflammatory diseases. The antiinflammatory properties of PARP-1 inhibitors have been demonstrated ameliorating effect in various neuroinflammatory disorders. It has been reported that there is a close relationship between the inflammatory processes and major depressive disorder. In the present study, we have elucidated the role of oxidative-nitrosative stress-PARP-1 pathway in lipopolysaccharide (LPS)-induced neurobehavioral and neurochemical alterations in mice. 3-Aminobenzamide (10 and 30mg/kg) and imipramine (10 and 30mg/kg) were administered once daily for 14days. Mice were challenged with LPS (1mg/kg, i.p.) 30min after drug administration on the 14th day. The mRNA expression level of PARP-1 (12h after LPS injection) in the hippocampus was measured through quantitative real-time PCR. All the behavioral and biochemical parameters were assessed at 24h after LPS injection. The expression level of PARP-1mRNA was found significantly up-regulated in the hippocampus at 12h after LPS administration. Results showed that the LPS-challenged mice exhibited an increase in immobility time seen in forced swimming test and tail suspension test. LPS increased the levels of proinflammatory cytokines and oxido-nitrosative stress parameters in the hippocampus. However, pretreatment with 3-aminobenzamide (30mg/kg) significantly reversed the LPS-induced alterations in behavioral parameters, proinflammatory cytokines, oxidative-nitrosative stress and PARP-1 mRNA levels. Imipramine failed to prevent the up-regulation of PARP-1 induced by LPS administration. Our results emphasized that oxidative-nitrosative stress-PARP-1 cascade can play a key role in LPS-induced neurobehavioral and neurochemical anomalies.
