Neurochem Res 2024; 49:1200-1211. [PMID: 38381245 DOI: 10.1007/s11064-024-04105-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Revised: 01/09/2024] [Accepted: 01/11/2024] [Indexed: 02/22/2024]
Abstract
Cognitive dysfunctions are now recognized as core symptoms of various psychiatric disorders e.g., major depressive disorder. Sustained immune activation may leads to cognitive dysfunctions. Proinflammatory cytokines shunt the metabolism of tryptophan towards kynurenine and quinolinic acid may accumulate at toxic concentrations. This acid triggers an increase in neuronal nitric oxide synthase function and promotes oxidative stress. The searching for small molecules that can regulate tryptophan metabolites produced in the kynurenic pathway has become an important goal in developing treatments for various central nervous system diseases with an inflammatory component. Previously we have identified a small hybrid molecule - MM165 which significantly reduces depressive-like symptoms caused by inflammation induced by lipopolysaccharide administration. In the present study, we investigated whether this compound would mitigate cognitive deficits induced by lipopolysaccharide administration and whether treatment with it would affect the plasma or brain levels of quinolinic acid and kynurenic acid. Neuroinflammation was induced in rats by administering lipopolysaccharide at a dose of 0.5 mg/kg body weight for 10 days. We conducted two tests: novel object recognition and object location, to assess the effect on memory impairment in animals previously treated with lipopolysaccharide. In plasma collected from rats, the concentrations of C-reactive protein and tumor necrosis factor alfa were determined. The concentrations of kynurenic acid and quinolinic acid were determined in plasma and homogenates obtained from the cerebral cortex of rats. Interleukin 6 in the cerebral cortex of rats was determined. Additionally, the body and spleen mass and spontaneous activity were measured in rats. Our study shows that MM165 may mitigate cognitive deficits induced by inflammation after administration of lipopolysaccharide and alter the concentrations of tryptophan metabolites in the brain. Compounds exhibiting a mechanism of action analogous to that of MM165 may serve as foundational structures for the development of a new class of antidepressants.

Abstract
There is an increasing interest in the pathophysiological role of the kynurenine pathway of tryptophan metabolism in the regulation of immune function and inflammation. We sought to address the link between this pathway and the presence rheumatic diseases (RD) by conducting a systematic review and meta-analysis of studies reporting the plasma or serum concentrations of tryptophan, kynurenine, and other relevant metabolites in RD patients and healthy controls. We searched electronic databases for relevant articles published between inception and the 30th of June 2023. Risk of bias and certainty of evidence were assessed using the Joanna Briggs Institute Critical Appraisal Checklist and the Grades of Recommendation, Assessment, Development and Evaluation Working Group system. In 24 studies selected for analysis, compared to controls, RD patients had significantly lower tryptophan (standard mean difference, SMD= -0.71, 95% CI -1.03 to -0.39, p<0.001; I2 = 93.6%, p<0.001; low certainty of evidence), and higher kynurenine (SMD=0.69, 95% CI 0.35 to 1.02, p<0.001; I2 = 93.2%, p<0.001; low certainty), kynurenine to tryptophan ratios (SMD=0.88, 95% CI 0.55 to 1.21, p<0.001; I2 = 92.9%, p<0.001; moderate certainty), 3-hydroxykynurenine (SMD=0.74, 95% CI 0.30 to 1.18, p=0.001; I2 = 87.7%, p<0.001; extremely low certainty), and quinolinic acid concentrations (SMD=0.71, 95% CI 0.31 to 1.11, p<0.001; I2 = 88.1%, p<0.001; extremely low certainty). By contrast, there were non-significant between-group differences in kynurenic acid, 3-hydroxyanthranilic acid, kynurenic acid to kynurenine ratio, or quinolinic acid to kynurenine acid ratio. In meta-regression, the SMD of tryptophan, kynurenine, and kynurenine to tryptophan ratio were not associated with age, publication year, sample size, RD duration, C-reactive protein, or use of anti-rheumatic drugs and corticosteroids. In subgroup analysis, the SMD of tryptophan, kynurenine, and kynurenine to tryptophan ratio was significant across different types of RD, barring rheumatoid arthritis. Therefore, we have observed significant alterations in tryptophan, kynurenine, 3-hydroxykynurenine, and quinolinic acid concentrations in RD patients. Further research is warranted to determine whether these biomarkers can be useful for diagnosis and management in this patient group. (PROSPERO registration number: CRD CRD42023443718).

Toll-Like Receptor 4 Plays a Significant Role in the Biochemical and Neurological Alterations Observed in Two Distinct Mice Models of Huntington's Disease. Mol Neurobiol 2023; 60:2678-2690.

Abstract
Toll-like receptors (TLRs) are central players in innate immunity responses. They are expressed in glial cells and neurons, and their overactivation leads to the production of proinflammatory molecules, neuroinflammation, and neural damage associated with many neurodegenerative pathologies, such as Huntington's disease (HD). HD is an inherited disorder caused by a mutation in the gene coding for the protein Huntingtin (Htt). Expression of mutated Htt (mHtt) causes progressive neuronal degeneration characterized by striatal loss of GABAergic neurons, oxidative damage, neuroinflammatory processes, and impaired motor behavior. The main animal models to study HD are the intrastriatal injection of quinolinic acid (QA) and the transgenic B6CBA-Tg (HDexon1)61Gpb/1 J mice (R6/1). Those models mimic neuronal damage and systemic manifestations of HD. The objective of this work was to study the participation of TLR4 in the manifestations of neuronal damage and HD symptoms in the two mentioned models. For this purpose, C57BL6/J and TLR4-KO mice were administered with QA, and after that motor activity, and neuronal and oxidative damages were measured. R6/1 and TLR4-KO were mated to study the effect of low expression of TLR4 on the phenotype manifestation in R6/1 mice. We found that TLR4 is involved in motor activity, and neurological and oxidative damage induced by intrastriatal injection of QA, and the low expression of TLR4 causes a delay in the onset of phenotypic manifestations by the mHtt expression in R6/1 mice. Our results show that TLR4 is involved in both models of HD and focuses then as a therapeutic target for some deleterious reactions in HD.

Neurochem Res 2022; 47:2728-2740. [PMID: 35604516 DOI: 10.1007/s11064-022-03627-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Revised: 04/19/2022] [Accepted: 05/05/2022] [Indexed: 11/28/2022]
Abstract
D-Serine has been shown to play an important role in the expression and control of a variety of brain functions by acting as the endogenous coagonist for the N-methyl-D-aspartate type glutamate receptor (NMDAR), at least, in the forebrain. To obtain further insight into the still debatable cellular localization of the D-amino acid, we have examined the effects of the selective destruction of the neuronal cell bodies by quinolinate on the tissue or extracellular D-serine concentrations in the medial prefrontal cortex of the rat. A local quinolinate infusion into the bilateral medial prefrontal cortex produced a cortical lesion with a marked (- 65%) and non-significant alteration (- 5%) in the cortical and striatal tissue D-serine concentrations, respectively, 7 days post-infusion. In vivo microdialysis experiments in the right prefrontal lesion site 9 days after the quinolinate application revealed that the basal extracellular D-serine levels were also dramatically reduced (- 64%). A prominent reduction in the tissue levels of GABA in the interneurons of the prefrontal cortex (- 78%) without significant changes in those in the striatum (+ 12%) verified that a major lesion part was confined to the cortical portion. The lack of a significant influence of the prefrontal quinolinate lesion on its dopamine concentrations in the mesocortical dopamine projections suggests that the nerve terminals and axons in the lesion site may be spared. These findings are consistent with the perikarya-selective nature of the present quinolinate-induced lesion and further support the view that neuronal cell bodies of intrinsic neurons in the prefrontal cortical region contain substantial amounts of D-serine, which may sustain the basal extracellular concentrations of D-serine.

Abstract
Huntington´s disease (HD) is a pathological condition that can be studied in mice by the administration of quinolinic acid (QUIN), an agonist of the N-methyl-d-aspartate receptor (NMDAR) that induces NMDAR-mediated cytotoxicity and neuroinflammation. Mast cells (MCs) participate in numerous inflammatory processes through the release of important amounts of histamine (HA). In this study, we aimed to characterize the participation of MCs and HA in the establishment of neural and oxidative damage in the QUIN-induced model of HD. C57BL6/J mice (WT), MC-deficient c-KitW-sh/W-sh (Wsh) mice and Wsh mice reconstituted by intracerebroventricular (i.c.v.) injection of 5 × 105 bone marrow-derived mast cells (BMMCs), or i.c.v. administered with HA (5 µg) were used. All groups of animals were intrastriatally injected with 1 µL QUIN (30 nmol/µL) and 3 days later, apomorphine-induced circling behavior, striatal GABA levels and the number of Fluoro-Jade positive cells, as indicators of neuronal damage, were determined. Also, lipid peroxidation (LP) and reactive oxygen species production (ROS), as markers of oxidative damage, were analyzed. Wsh mice showed less QUIN-induced neuronal and oxidative damage than WT and Wsh-MC reconstituted animals. Histamine administration restored the QUIN-induced neuronal and oxidative damage in the non-reconstituted Wsh mice to levels equivalent or superior to those observed in WT mice. Our results demonstrate that MCs and HA participate in the neuronal and oxidative damages observed in mice subjected to the QUIN -induced model of Huntington's disease.

Abstract
Vascular dementia (VaD) is the second most common form of dementia worldwide. It is caused by cerebrovascular disease, and patients often show severe impairments of advanced cognitive abilities. Nitric oxide synthase (NOS) and nitric oxide (NO) play vital roles in the pathogenesis of VaD. The functions of NO are determined by its concentration and bioavailability, which are regulated by NOS activity. The activities of different NOS subtypes in the brain are partitioned. Pathologically, endothelial NOS is inactivated, which causes insufficient NO production and aggravates oxidative stress before inducing cerebrovascular endothelial dysfunction, while neuronal NOS is overactive and can produce excessive NO to cause neurotoxicity. Meanwhile, inflammation stimulates the massive expression of inducible NOS, which also produces excessive NO and then induces neuroinflammation. The vicious circle of these kinds of damage having impacts on each other finally leads to VaD. This review summarizes the roles of the NOS/NO pathway in the pathology of VaD and also proposes some potential therapeutic methods that target this pathway in the hope of inspiring novel ideas for VaD therapeutic approaches.

Hepatic nitric oxide synthase 1 adaptor protein regulates glucose homeostasis and hepatic insulin sensitivity in obese mice depending on its PDZ binding domain. EBioMedicine 2019; 47:352-364.

Abstract
BACKGROUND NOS1AP is an adaptor protein and its SNP rs12742393 was associated with type 2 diabetes (T2D). However, it remains uncertain whether NOS1AP plays a role in regulation of insulin sensitivity. Hepatic insulin resistance contributed to the development of T2D. Here, our investigation was focused on whether NOS1AP is involved in the regulation of hepatic insulin sensitivity and its underlying mechanisms. METHODS Liver specific NOS1AP condition knockout (CKO) and NOS1AP overexpression mice were generated and given a high fat diet. SNPs of NOS1AP gene were genotyped in 86 human subjects. FINDINGS NOS1AP protein is expressed in human and mouse liver. CKO mice exhibited impaired pyruvate, glucose and insulin tolerance, and increased lipid deposits in the liver. Conversely, NOS1AP overexpression in livers of obese mice improved pyruvate and/or glucose, and insulin tolerance, and attenuated liver lipid accumulation. Moreover, hepatocytes from CKO mice exhibited an elevated glucose production and mRNA expressions of Pc and Pck1. Overexpression of NOS1AP potentiated insulin-stimulated activation of IR/Akt in livers from obese mice. The insulin sensitizing effect of NOS1AP could be mimicked by overexpression of C-terminal domain of NOS1AP in ob/ob mice. Furthermore, NOS1AP overexpression in liver significantly inhibited p38 MAPK phosphorylation, and maintained ER homeostasis through p-eIF2a-ATF4-CHOP pathway. Subjects with rsl2742393 of NOS1AP have higher risk to develop hepatic steatosis. INTERPRETATION Our data demonstrate a novel role of NOS1AP in regulating hepatic insulin sensitivity and p38 MAPK inactivation in obese mice, which makes NOS1AP a potential therapeutic target for the prevention and treatment of T2D.
