Innate immunity and metal ion trafficking pathway perturbations in idiopathic Parkinson's disease and Tuberculosis: A comparative transcriptomics approach
Introduction: The purpose of our study is to detect and compare common, significantly enriched pathways in peripheral blood mononuclears (PBMC) and CNS tissue donated by idiopathic Parkinson's Disease (iPD) patients and compare their transcriptomic profiles with those donated by tuberculosis (T...

| Sumario: | Introduction: The purpose of our study is to detect and compare common, significantly enriched pathways in peripheral blood mononuclears (PBMC) and CNS tissue donated by idiopathic Parkinson's Disease (iPD) patients and compare their transcriptomic profiles with those donated by tuberculosis (TB) patients. Methods: We performed comparative transcriptomic analyses between gene expression studies published in the GEO Datasets repository, retrieved as queries of iPD and TB each vs healthy controls. Results: Datasets retrieved involved iPD: 2 PBMC studies, 1 Substantia Nigra (SN) and 1 Dorsal Motor Nucleus of the Vagus (DMNV) study, as well as TB: 1 PBMC and one study with monocyte (Mc) gene expression profiles. Among significantly enriched pathways were the influenza A (IAV) associated “Viral mRNA Translation” and “L13a-mediated translational silencing of Ceruloplasmin expression”, common between DMNV, active Tb Monocytes (TBA Mc), post-treatment TB and both iPD PBMC datasets. Discussion: Our results support the hypothesis that remnant, postinfectious epigenetic changes on PBMCs inflicted by Mycobacterium Tuberculosis (Mtb) may alter their phenotype, facilitating non-abortive intracellular residency for a subsequent pathogen. This pathogen may be transmissible to the CNS via sites such as the vagal projections, and prime iPD pathogenesis by disrupting metal ion homeostasis in a lifecycle – dependent manner. |
