Long noncoding RNAs (lncRNAs) are RNA molecules of 200 nucleotides or more in length that not translated into proteins. Their expression is tissue-specific, with the vast majority involved regulation cellular processes and functions. Many human diseases, including cancer, have been shown to be associated deregulated lncRNAs, rendering them potential therapeutic targets biomarkers for differential diagnosis.

Abstract Neurological disorders such as stroke, multiple sclerosis, well the neurodegenerative diseases Parkinson's or Alzheimer's disease are accompanied even powered by danger associated molecular patterns (DAMPs), defined endogenous molecules released from stressed damaged tissue. Besides protein-related DAMPs “alarmins”, numerous nucleic acid exist in body fluids, cell-free nuclear and mitochondrial DNA different species of extracellular RNA, collectively termed self-extracellular acids (SENAs). Among these, microRNA, long non-coding RNAs, circular RNAs ribosomal RNA constitute majority RNA-based DAMPs. Upon tissue injury, necrosis apoptosis, SENAs neuronal, immune other cells predominantly association with vesicles may be translocated to target where they can induce intracellular regulatory pathways gene transcription translation. The SENA-induced signaling reactions brain appear related neuroinflammatory processes, often causally onset progression respective disease. In this review, impact diverse types on will discussed.

Immune cell function is critically dependent on precise control over transcriptional output from the genome. In this respect, integration of environmental signals that regulate gene expression, specifically by transcription factors, enhancer DNA elements, genome topography and non-coding RNAs (ncRNAs), are key components. The first three have been extensively investigated. Even though represent vast majority cellular RNA species, class remains historically understudied. This partly because a lag in technological bioinformatic innovations capable identifying accurately measuring their expression.

Introduction Upper limb (UL) impairment is common in people with multiple sclerosis (pwMS), and functional recovery of the UL a key rehabilitation goal. Technology-based approaches, like virtual reality (VR), are increasingly promising. While most VR environments task-oriented, our clinical approach integrates neuroproprioceptive ‘facilitation inhibition’ (NFI) principles. To advance this, we developed immersive software based on NFI principles targeting function sit-to-stand ability. This study aims to evaluate effectiveness this therapy compared conventional NFI-based physical pwMS. Our uniquely applies advanced imaging techniques, along biological molecular assessments, explore adaptive processes induced by rehabilitation. Methods analysis double-arm, randomised, assessor-blinded, controlled trial runs over 2 months (1 hour, times per week). PwMS mild severe disability will receive either or real-world therapy.
