Background And Objectives: Primary progressive multiple sclerosis (PPMS) displays a highly variable disease progression with a characteristic accumulation of disability, what makes difficult its diagnosis and efficient treatment. The identification of microRNAs (miRNAs)-based signature for the early detection in biological fluids could reveal promising biomarkers to provide new insights into defining MS clinical subtypes and potential therapeutic strategies. The objective of this cross-sectional study was to describe PPMS miRNA profiles in CSF and serum samples compared with other neurologic disease individuals (OND) and relapsing-remitting MS (RRMS).

Article Synopsis
  • The study investigates how disease-modifying therapies, specifically anti-CD20 treatments and sphingosine 1-phosphate receptor modulators (S1PRM), affect immune responses to SARS-CoV-2 vaccines in patients with multiple sclerosis (MS) and other autoimmune diseases.
  • Researchers enrolled 457 patients and measured both humoral (antibody) and cellular (T-cell) immune responses before and after vaccination, finding that responses varied based on treatment type and duration.
  • Results indicate that while anti-CD20 and S1PRM treatments can reduce antibody responses, anti-CD20 patients may still generate T-cell responses even without detectable antibodies, highlighting the complexities of vaccine response in these populations.

Background: The study of circulating miRNAs in CSF has gained tremendous attention during the last years, as these molecules might be promising candidates to be used as biomarkers and provide new insights into the disease pathology of neurological disorders.

Objective: The main aim of this study was to describe an OpenArray panel of CSF-enriched miRNAs to offer a suitable tool to identify and characterize new molecular signatures in different neurological diseases.

Methods: Two hundred and fifteen human miRNAs were selected to be included in the panel, and their expression and abundance in CSF samples were analyzed.

Some clinical and biological characteristics have been described as prognostic factors for clinical conversion into clinically definite multiple sclerosis in radiologically isolated syndrome (RIS) population. The aim of this study was to assess signatures of circulating miRNAs in those patients according to their conversion status after 5 years of follow-up. OpenArray plates assessing 216 miRNA candidates were run in 15 RIS patients, and their relative abundances were analyzed.

Background: MicroRNAs (miRNAs) have been reported as deregulated in active brain lesions derived from patients with multiple sclerosis (MS). In there, these post-transcriptional regulators may elicit very important effects but proper identification of miRNA candidates as potential biomarkers and/or therapeutic targets is scarcely available.

Objective: The aim of the study was to detect the presence of a set of candidate miRNAs in cell-free cerebrospinal fluid (CSF) and to determine their association with gadolinium-enhancing (Gd+) lesions in order to assess their value as biomarkers of MS activity.
