- To investigate the shared molecular mechanisms between Parkinson's disease (PD) and COVID-19 through integrated bioinformatics analysis and single-cell RNA sequencing (scRNA-seq). We conducted a comprehensive analysis of bulk RNA-seq data from publicly available databases, along with scRNA-seq data from brain tissues of COVID-19 patients. Differential expression analysis identified 725 differentially expressed genes (DEGs) in COVID-19 and 633 in PD samples. A total of 77 overlapping DEGs were identified, highlighting common pathways associated with neuroinflammation and dopaminergic neuron dysfunction. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses revealed significant enrichment in inflammation-related pathways. The protein-protein interaction network analysis identified CHI3L1 as a key gene linking PD and COVID-19. ScRNA-seq analysis revealed a significant increase in CHI3L1-expressing astrocytes in COVID-19 samples, indicating a potential mechanism by which COVID-19 may exacerbate PD symptoms. Furthermore, cell-cell communication analysis revealed enhanced interactions between astrocytes and microglia, excitatory neurons, or oligodendrocytes through signaling molecules such as phosphoprotein 1, CADM1, NCAM1, NRG, and NRXN1, suggesting that astrocytes play a central role in regulating neuronal excitability, synaptic plasticity, and immune responses in the context of COVID-19. These findings suggest a complex interplay between COVID-19 and PD, emphasizing the need for further investigation into the shared pathogenic mechanisms and potential therapeutic targets.IMPORTANCEThis study demonstrates the critical role of neuroinflammation and dopaminergic neuron damage in the shared pathogenesis of COVID-19 and Parkinson's disease. CHI3L1 emerges as a key target, highlighting its potential involvement in modulating neuroinflammatory pathways and synaptic plasticity. The functional significance of CHI3L1, along with its pathological relevance, warrants further investigation through larger studies. Additionally, the active intercellular communication among astrocytes, microglia, and excitatory neurons underscores the profound impact of COVID-19 on neural circuitry. Collectively, these results provide important insights into the mechanisms driving the neurodegenerative consequences of COVID-19, emphasizing the need for continued exploration of therapeutic interventions and the long-term neurological effects of viral infection. - Source: PubMed

Li LiangyuJiang JunGuo LizhongSantos JavierGonzález Ana MaríaLi SiyiQin Yi - Cachexia is a syndrome characterized by an ongoing loss of skeletal muscle mass associated with poor patient prognosis in non-small cell lung cancer (NSCLC). However, prognostic cachexia biomarkers in NSCLC are unknown. Here, we analyzed computed tomography (CT) images and tumor transcriptome data to identify potentially secreted cachexia biomarkers (PSCB) in NSCLC patients with low-muscularity. We integrated radiomics features (pectoralis muscle, sternum, and tenth thoracic (T10) vertebra) from CT of 89 NSCLC patients, which allowed us to identify an index for screening muscularity. Next, a tumor transcriptomic-based secretome analysis from these patients (discovery set) was evaluated to identify potential cachexia biomarkers in patients with low-muscularity. The prognostic value of these biomarkers for predicting recurrence and survival outcome was confirmed using expression data from eight lung cancer datasets (validation set). Finally, C2C12 myoblasts differentiated into myotubes were used to evaluate the ability of the selected biomarker, interleukin (IL)-8, in inducing muscle cell atrophy. We identified 75 over-expressed transcripts in patients with low-muscularity, which included and . Also, we identified , , , , , , and as PSCB in the tumor secretome. These PSCB were capable of distinguishing worse and better prognosis (recurrence and survival) in NSCLC patients. was confirmed as a predictor of worse prognosis in all validation sets. In vitro assays revealed that IL-8 promoted C2C12 myotube atrophy. Tumors from low-muscularity patients presented a set of upregulated genes encoding for secreted proteins, including pro-inflammatory cytokines that predict worse overall survival in NSCLC. Among these upregulated genes, expression in NSCLC tissues was associated with worse prognosis, and the recombinant IL-8 was capable of triggering atrophy in C2C12 myotubes. - Source: PubMed

Cury Sarah Santilonide Moraes DiogoFreire Paula Pacciellide Oliveira GrasieliMarques Douglas Venâncio PereiraFernandez Geysson JavierDal-Pai-Silva MaeliHasimoto Érica NishidaDos Reis Patricia PintorRogatto Silvia ReginaCarvalho Robson Francisco - Many membrane proteins are subjected to limited proteolyses at their juxtamembrane regions, processes referred to as ectodomain shedding. Shedding ectodomains of membrane-bound ligands results in activation of downstream signaling pathways, whereas shedding those of cell adhesion molecules causes loss of cell-cell contacts. Secreted proteomics (secretomics) using high-resolution mass spectrometry would be strong tools for both comprehensive identification and quantitative measurement of membrane proteins that undergo ectodomain shedding. In this study, to elucidate the ectodomain shedding events that occur during neuronal differentiation, we establish a strategy for quantitative secretomics of glycoproteins released from differentiating neuroblastoma cells into culture medium with or without GM6001, a broad-spectrum metalloprotease inhibitor. Considering that most of transmembrane and secreted proteins are N-glycosylated, we include a process of N-glycosylated peptides enrichment as well as isotope tagging in our secretomics workflow. Our results show that differentiating N1E-115 neurons secrete numerous glycosylated polypeptides in metalloprotease-dependent manners. They are derived from cell adhesion molecules such as NCAM1, CADM1, L1CAM, various transporters and receptor proteins. These results show the landscape of ectodomain shedding and other secretory events in differentiating neurons and/or during axon elongation, which should help elucidate the mechanism of neurogenesis and the pathogenesis of neurological disorders. - Source: PubMed

Tsumagari KazuyaShirakabe KyokoOgura MayuSato FuminoriIshihama YasushiSehara-Fujisawa Atsuko - ST8SIA2 is a polysialyltransferase that attaches polysialic acid to the glycoproteins NCAM1 and CADM1. Polysialylation is involved in brain development and plasticity. ST8SIA2 is a schizophrenia candidate gene, and St8sia2 mice exhibit schizophrenia-like behavior. We sought to identify new pathological consequences of ST8SIA2 deficiency. Our proteomic analysis suggested myelin impairment in St8sia2 mice. Histological and immune staining together with Western blot revealed that the onset of myelination was not delayed in St8sia2 mice, but the content of myelin was lower. Ultrastructure analysis of the corpus callosum showed thinner myelin sheaths, smaller and irregularly shaped axons, and white matter lesions in adult St8sia2 mice. Then we evaluated oligodendrocyte differentiation in vivo and in vitro. Fewer OLIG2+ cells in the cortex and corpus callosum, together with the higher percentage of undifferentiated oligodenroglia in St8sia2 mice suggested an impairment in oligodendrocyte generation. Experiment on primary cultures of oligodendrocyte precursor cells (OPCs) confirmed a cell-autonomous effect of ST8SIA2 in oligodendroglia, and demonstrated that OPC to oligodendrocyte transition is inhibited in St8sia2 mice. Concluding, ST8SIA2-mediated polysialylation influences on oligodendrocyte differentiation, and oligodendrocyte deficits in St8sia2 mice are a possible cause of the demyelination and degeneration of axons, resembling nerve fiber alterations in schizophrenia.
