Monoamine oxidase is classified into type A and B (MAO-A, MAO-B) according to the substrate specificity and sensitivity to inhibitors. The isoenzymes are different proteins coded by different genes localized on the X-chromosome, but they have identical intron-exon organization, similar protein structure and enzymatic mechanism and are considered to be derived from the same ancestral gene. The isoform-specific transcription organization regulates expression and function of MAO-A in response to cellular signaling pathways and environmental factors. MAO-A shows distinct properties and functions: isoform-specified polymorphisms, localization in catecholamine neurons, expression during early embryonic stage, regulation of brain architecture development and mediation of death and survival of neuronal cells. MAO-A is more flexible to genetic and environmental changes than MAO-B. Defective MAO-A expression impairs embryonic brain development and causes adult abnormal mood and behavior, as shown by human male cases with MAO-A deletion. This paper presents the regulation of brain MAO-A expression epigenetically by interaction between genetic and environmental factors. Association of aberrant MAO-A expression and activity with aggression, asocial behaviors, depressive disorders, and neurodegenerative diseases is discussed. Novel therapeutic strategy for psychiatric diseases by intervention to the regulation of MAO-A expression and activity is proposed.</p>","PeriodicalId":16579,"journal":{"name":"Journal of Neural Transmission","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142769874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, research on MPTP-induced experimental parkinsonism has significantly advanced our understanding. In this model, it is widely accepted that mitochondrial respiratory failure is the primary mechanism of cell death. Studies have shown that a toxic metabolite of MPTP inhibits Complex I and alpha-ketoglutarate dehydrogenase activities in mitochondria. Since then, many research groups have focused on mitochondrial dysfunction in PD, identifying deficiencies in Complex I or III in PD patients' brains, skeletal muscle, and platelets. There is some debate about the decline in mitochondrial function in peripheral organs. However, since α-synuclein, the main component protein of Lewy bodies, accumulates in peripheral organs, it is reasonable to consider PD a systemic disease. Additionally, mutant mitochondrial DNA with a 4,977 base pair deletion has been found in the brains of PD patients, suggesting that age-related accumulation of deleted mtDNA is accelerated in the striatum and may contribute to the pathophysiology of PD. While the cause of PD remains unknown, mitochondrial dysfunction is undoubtedly a factor in cell death in PD. In addition, the causative gene for familial PD, parkin (now PRKN), and PTEN-induced putative kinase 1 (PINK1), both gene products are also involved in mitochondrial quality control. Moreover, we have successfully isolated and identified CHCHD2, which is involved in the mitochondrial electron transfer system.

Recent studies have suggested that hypomimia is not only related to motor dysfunction but also to impairment in emotional processing networks. Therefore, we hypothesized that the severity of hypomimia could be associated with performance on a task aimed at assessing facial emotion recognition. In this study, we explored the association between hypomimia, recognition of facial expressions of basic emotions using the Ekman 60 Faces Test (EF), and brain correlates of both hypomimia and performance on the EF. A total of 94 subjects underwent clinical assessments (neurological and neuropsychological examinations), and 56 of them participated in the neuroimaging study. We found significant correlation between hypomimia, EF Disgust (r = -0.242, p = 0.022) and EF Happiness (r = -0.264, p = 0.012); an independent reduction in Cortical Thickness (Cth) in the postcentral gyrus, insula, middle and superior temporal gyri, supramarginal gyrus, banks of the superior temporal sulcus, bilateral fusiform gyri, entorhinal cortex, parahippocampal gyrus, inferior and superior parietal cortex, and right cuneus and precuneus; and multiple correlations between negative emotions such as EF Disgust or EF Anger and a reduced Cth in fronto-temporo-parietal regions.

Events associated with the neuroinflammatory cascades, such as ageing, immunologic dysfunction, and eventually disruption of the blood-brain barrier and the \"cytokine storm\", appear to be orchestrated mainly through the activation of microglial cells and communication with the neurons. The inflammatory processes prompt cellular protein dyshomeostasis. Parkinson's and Alzheimer's disease share a common feature marked by characteristic pathological hallmarks of abnormal neuronal protein accumulation. These Lewy bodies contain misfolded α-synuclein aggregates in PD or in the case of AD, they are Aβ deposits and tau-containing neurofibrillary tangles. Subsequently, these abnormal protein aggregates further elicit neurotoxic processes and events which contribute to the onset of neurodegeneration and to its progression including aggravation of neuroinflammation. However, there is a caveat for exclusively linking neuroinflammation with neurodegeneration, since it's highly unlikely that immune dysregulation is the only factor that contributes to the manifestation of many of these neurodegenerative disorders. It is unquestionably a complex interaction with other factors such as genetics, age, and environment. This endorses the \"multiple hit hypothesis\". Consequently, if the host has a genetic susceptibility coupled to an age-related weakened immune system, this makes them more susceptible to the virus/bacteria-related infection. This may trigger the onset of chronic cytotoxic neuroinflammatory processes leading to protein dyshomeostasis and accumulation, and finally, these events lead to neuronal destruction. Here, we differentiate \"neuroinflammation\" and \"inflammation\" with regard to the involvement of the blood-brain barrier, which seems to be intact in the case of neuroinflammation but defect in the case of inflammation. There is a neuroinflammation-inflammation continuum with regard to virus-induced brain affection. Therefore, we propose a staging of this process, which might be further developed by adding blood- and CSF parameters, their stage-dependent composition and stage-dependent severeness grade. If so, this might be suitable to optimise therapeutic strategies to fight brain neuroinflammation in its beginning and avoid inflammation at all.</p>","PeriodicalId":16579,"journal":{"name":"Journal of Neural Transmission","volume":" ","pages":"1429-1453"},"PeriodicalIF":3.2,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11608394/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139521174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Depressive symptoms occur in all stages of HD, beginning in presymptomatic HD gene carriers, and are strongly associated with suicidal ideation and suicidality, but their relationship with other clinical dimensions in HD is controversial and the underlying pathophysiology is poorly understood. Analysis of the available literature until November 2023 concerned the prevalence, clinical manifestations, neuroimaging, transgenic models, and treatment options of HD depression. While it was believed that depression in HD is due to psychosomatic factors in view of the fatal disease, studies in transgenic models of HD demonstrated molecular changes including neurotrophic and serotonergic dysregulation and disorders of the hypothalamic-pituitary-adrenal axis inducing depression-like changes. While relevant neuropathological data are missing, recent neuroimaging studies revealed correlations between depressive symptoms and dysfunctional connectivities in the default mode network, basal ganglia and prefrontal cortex, and changes in limbic and paralimbic structures related to the basic neurodegenerative process. The impact of response to antidepressants in HD patients is controversial; selective serotonin reuptake inhibitors are superior to serotonin-norepinephrine reuptake inhibitors, while electroconvulsive therapy may be effective for pharmacotherapy resistant cases.
