Biomarkers of Synaptic Damage in Multiple Sclerosis

Brief description of study

A prospective and retrospective cohort study of about five years will be performed on blood and cerebrospinal fluid samples taken for diagnostic reasons from recruited patients within the Neuromed Neurology Unit. Subjects with other chronic neurodegenerative diseases such as Amyotrophic lateral sclerosis (ALS), Alzheimer's disease (AD) and Parkinson's disease (PD), and healthy subjects subjected to blood sampling and / or lumbar puncture for clinical reasons will be recruited As control groups.

Detailed Study Description

Blood and cerebrospinal fluid samples will be subjected to the procedures required for the isolation of the different components immediately after the withdrawal. Subsequently, the levels of microRNAs, cytokines, chemokines, cell growth factors, neuronal damage markers (tau, phosphorylated and truncated tau, neurofilaments) and mitochondrial (lactate) and free d-amino acids (Objective 1) will be determined. Furthermore, synaptic alterations will be evaluated in the ex vivo chimeric model of MS, using the patch-clamp technique (Objective 2). Genotyping studies will be conducted in order to identify single nucleotide polymorphisms (SNPs) in coding and / or regulating regions of genes (microRNAs or proteins) involved in alterations of the synaptic transmission of MS and its murine experimental model (i.e. SLC1A3, NGFB, PDGFA, etc.), which correlate with specific clinical parameters (i.e. EDSS, BREMS, disease progression index, MS type, disease activity, etc.) and with the levels of potential biomarkers identified
