Introduction:
MicroRNAs (miRNAs) are molecules that in the last decade have gained increased attention a key mediator of the process of gene silencing in mammals. Deregulation of miRNAs is linked to illnesses such as cancer, and autoimmunity. Different reports claim for these molecules pivotal roles in both neuronal and immune processes, as well as in prediction of diseases affecting both systems. Multiple sclerosis (MS) is an example of an illness affecting myelin of axons, caused by autoimmune deregulation.
Aim:
To show the close relationship of the functions of miRNAs and their deregulation processes related to the immune and brain mechanisms in MS. In addition, we illustrate the use of miRNAs a potential noninvasive diagnostics for the assessment of the health status of a patient with MS.
Development:
In the scientific literature, there has been a widely identified role of miRNAs as modulators. However, little is known about the role that these molecules perform together with glial cells in neuronal plasticity and de/re- myelination processes. In spite of the acknowledged role played by miRNAs in all function, little has been investigated on their potential. An overview is presented here in the research, development and implementation o diagnostic techniques relating miRNA and MS.
Conclusions:
There is strong evidence of the role of miRNA and homeostatic processes of brain's white matter in MS. In a field study to exploit and can aid in early diagnosis and also in the development of therapies based on the use of miRNAs.
Insights
MicroRNAs (miRNAs) are key to gene silencing and are linked to autoimmune diseases like multiple sclerosis (MS). Research highlights their role in MS diagnosis and therapy development.
Area of Science:
- Molecular Biology
- Neuroimmunology
- Genetics
Context:
- MicroRNAs (miRNAs) are crucial gene regulators implicated in mammalian gene silencing.
- miRNA deregulation is associated with diseases including cancer, autoimmunity, and neurological disorders.
- Multiple Sclerosis (MS) involves autoimmune-mediated damage to neuronal myelin.
Purpose:
- To elucidate the intricate connection between miRNA function, deregulation, and immune/brain mechanisms in MS.
- To explore the potential of miRNAs as noninvasive biomarkers for assessing MS patient health status.
Summary:
- This review examines the established role of miRNAs in modulating cellular processes and their specific involvement in glial cells, neuronal plasticity, and myelin dynamics in MS.
- It provides an overview of current research, development, and implementation of diagnostic techniques leveraging miRNAs for MS.
Impact:
- Strong evidence supports the role of miRNAs in maintaining white matter homeostasis in the MS brain.
- Exploiting miRNAs offers potential for early MS diagnosis and the development of novel miRNA-based therapies.
