Sex-Specific Cross Tissue Meta-Analysis Identifies Immune Dysregulation in Women With Alzheimer's Disease. Front Aging Neurosci 2021; 13:735611. [PMID: 34658838 PMCID: PMC8515049 DOI: 10.3389/fnagi.2021.735611] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Accepted: 09/01/2021] [Indexed: 01/09/2023] Open
Abstract
Background: Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia in the United States. In spite of evidence of females having a greater lifetime risk of developing Alzheimer's Disease (AD) and greater apolipoprotein E4-related (APOE ε4) AD risk compared to males, molecular signatures underlying these differences remain elusive. Methods: We took a meta-analysis approach to study gene expression in the brains of 1,084 AD patients and age-matched controls and whole blood from 645 AD patients and age-matched controls in seven independent datasets. Sex-specific gene expression patterns were investigated through use of gene-based, pathway-based and network-based approaches. The ability of a sex-specific AD gene expression signature to distinguish Alzheimer's disease from healthy controls was assessed using a linear support vector machine model. Cell type deconvolution from whole blood gene expression data was performed to identify differentially regulated cells in males and females with AD. Results: Strikingly gene-expression, network-based analysis and cell type deconvolution approaches revealed a consistent immune signature in the brain and blood of female AD patients that was absent in males. In females, network-based analysis revealed a coordinated program of gene expression involving several zinc finger nuclease genes related to Herpes simplex viral infection whose expression was modulated by the presence of the APOE ε4 allele. Interestingly, this gene expression program was missing in the brains of male AD patients. Cell type deconvolution identified an increase in neutrophils and naïve B cells and a decrease in M2 macrophages, memory B cells, and CD8+ T cells in AD samples compared to controls in females. Interestingly, among males with AD, no significant differences in immune cell proportions compared to controls were observed. Machine learning-based classification of AD using gene expression from whole blood in addition to clinical features produced an improvement in classification accuracy upon stratifying by sex, achieving an AUROC of 0.91 for females and 0.80 for males. Conclusion: These results help identify sex and APOE ε4 genotype-specific transcriptomic signatures of AD and underscore the importance of considering sex in the development of biomarkers and therapeutic strategies for AD.

Abstract
This study investigated if a prior long-term physical exercise protocol protects the substantia nigra and the striatum against oxidative stress and motor deficits in a Parkinson Disease model induced by 6-hydroxydopamine. Three animal treatment groups were included in the study: sham; 6-hydroxydopamine and 6-hydroxydopamine/exercise. Previously to the intrastriatal lesion by 6-hydroxydopamine, rats in the exercise groups performed a swimming program for 18 weeks. The rats were submitted to behavioral tests before and after intrastriatal 6-hydroxydopamine injection. The oxidative stress was analyzed by Thiobarbituric Acid Reactive Substances and Glutathione reductase activity methods. The exercise decreased lipid peroxidation and increased glutathione reductase activity in the substantia nigra. In contrast, in the striatum, exercise increased lipid peroxidation and decreased glutathione reductase activity. Exercise increased contralateral rotations and reduces immobility levels at 14 days post lesion. The exercise prior to 6-OHDA lesion had protective action only in substantia nigra against oxidative stress.

Cannabinoid Receptor Type 1 Agonist ACEA Protects Neurons from Death and Attenuates Endoplasmic Reticulum Stress-Related Apoptotic Pathway Signaling. Neurotox Res 2017; 33:846-855. [PMID: 29134561 DOI: 10.1007/s12640-017-9839-1] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2017] [Revised: 10/11/2017] [Accepted: 11/02/2017] [Indexed: 02/02/2023]
Abstract
Neurodegeneration is the result of progressive destruction of neurons in the central nervous system, with unknown causes and pathological mechanisms not yet fully elucidated. Several factors contribute to neurodegenerative processes, including neuroinflammation, accumulation of neurotoxic factors, and misfolded proteins in the lumen of the endoplasmic reticulum (ER). Endocannabinoid signaling has been pointed out as an important modulatory system in several neurodegeneration-related processes, inhibiting the inflammatory response and increasing neuronal survival. Thus, we investigated the presumptive protective effect of the selective cannabinoid type 1 (CB1) receptor agonist arachidonyl-2'-chloroethylamide (ACEA) against inflammatory (lipopolysaccharide, LPS) and ER stress (tunicamycin) stimuli in an in vitro neuronal model (Neuro-2a neuroblastoma cells). Cell viability analysis revealed that ACEA was able to protect against cell death induced by LPS and tunicamycin. This neuroprotective effect occurs via the CB1 receptor in the inflammation process and via the transient receptor potential of vanilloid type-1 (TRPV1) channel in ER stress. Furthermore, the immunoblotting analyses indicated that the neuroprotective effect of ACEA seems to involve the modulation of eukaryotic initiation factor 2 (eIF2α), transcription factor C/EBP homologous protein (CHOP), and caspase 12, as well as the survival/death p44/42 MAPK, ERK1/2-related signaling pathways. Together, these data suggest that the endocannabinoid system is a potential therapeutic target in neurodegenerative processes, especially in ER-related neurodegenerative diseases.

Abstract
Parkinson's disease (PD) is one of the most common neurodegenerative diseases whose relentless progression results in severe disability. Although PD aetiology is unknown, growing evidences point to the mitochondrial involvement in the pathobiology of this disorder. So, it seems imperative to understand the means by which the molecular pathways harboured in this organelle are regulated. With the advances in MS-based proteomics, there is a substantial expectation in the increased knowledge of mitochondrial protein dynamics. Still, few studies have been performed on mitochondrial protein profiling in the context of PD. In order to integrate data from these studies, network analyses were performed taking into consideration variables such as model of PD, cell line, or tissue origin. Overall, data retrieved from these analyses highlighted the modulation of the biological processes related with "generation of energy," "cellular metabolism," and "mitochondrial transport" in PD. However, it was noted that the impact of sample type and/or PD model on the biological processes was modulated by the disease. Moreover, technical considerations related to protein characterization using gel-based or gel-free MS approaches should be considered in data comparison among different studies. Data from the present review will help to envisage future studies targeting these mechanisms.

Abstract
Salvia lavandulifolia Vahl., known as "Spanish sage", has potential value in dementia for its sedative, antioxidant, anti-inflammatory and anticholinesterase properties. This work aimed to evaluate the in vitro neuroprotective activity of S. lavandulifolia essential oils, obtained from plants at different phenological stages (vegetative and flowering phases) and plants grown at different densities, against H2O2-induced oxidative stress in PC12 cells. The effect on cell viability and morphology, lipid peroxidation, GSH/GSSG ratio, intracellular ROS levels, antioxidant enzymes (CAT, SOD, GR, GPx, HO-1) and apoptotic enzymes was investigated. Comparing with H2O2-treated PC12 cells, pretreatments with essential oil samples attenuated morphological changes and loss of cell viability, decreased MDA levels and intracellular ROS production and increased GSH/GSSG ratio. Moreover, Spanish sage increased antioxidant status as evidenced in an increase of antioxidant enzyme activity and protein expression and inhibited caspase-3 activity. Furthermore, our results suggest that S. lavandulifolia essential oils are able to activate Nrf2 transcription factor. Collectively, the sample of essential oil obtained with the highest densities of planting and at flowering phase exerted the major neuroprotective activity. Our findings demonstrate that S. lavandulifolia essential oils may have therapeutic value for the prevention and treatment of neurodegenerative diseases associated with oxidative stress-induced neuronal injury.

Abstract
Objetivo: Analisar as funções executivas de idosos com doença de Parkinson (DP – com e sem quadro demencial) e doença de Alzheimer (DA), e confrontar os escores dos participantes no que se refere às atividades funcionais da vida diária e à habilidade motora em situações de dupla tarefa. Métodos: Sob um desenho transversal, 54 idosos foram divididos em quatro grupos: G1, composto por 11 sujeitos com DP; G2, formado por 10 sujeitos com demência de Parkinson; G3, composto por 13 participantes com DA; e G4, formado por 20 idosos saudáveis. Os procedimentos metodológicos envolveram análise das funções cognitivas pré-frontais dos sujeitos, da realização das atividades da vida diária e da habilidade motora em situações de dupla tarefa. A análise dos dados envolveu a estatística descritiva (média e erro-padrão) e inferencial (teste ANOVA e pós-teste de Scheffé), admitindo significância de 5% (p < 0,05) e intervalo de confiança de 95%. Resultados: As funções cognitivas pré-frontais apresentaram diferença significativa entre os grupos, sobretudo nas comparações envolvendo G2 e G3, em relação a G1 e G4 (p = 0,001). Os grupos com déficit cognitivo apresentaram pior rendimento na realização das atividades da vida diária, com menor escore do G2, na qual há junção de déficit cognitivo e motor (p = 0,001). Em situações de dupla tarefa, G2 e G3 apresentaram maiores dificuldades que os demais grupos (p < 0,05). Conclusão: Distúrbios pré-frontais repercutem negativamente nas atividades funcionais e na habilidade psicomotora dos indivíduos. Quando não vinculado a quadro demencial, os pacientes com DP apresentaram escores cognitivos pré-frontais e independência funcional semelhantes aos de idosos saudáveis.
