Insights

MicroRNAs (miRNAs) influence T helper 17 (Th17) cell differentiation in multiple sclerosis (MS). This review explores how miRNAs regulate Th17 cells in MS pathophysiology and identifies potential therapeutic targets.

Area of Science:

  • Neuroimmunology
  • Molecular Biology

Background:

  • Multiple sclerosis (MS) is an immune-mediated central nervous system disorder.
  • T helper 17 (Th17) cells are key players in MS-related neuroinflammation.
  • MicroRNAs (miRNAs) are implicated in MS disease activity and progression.

Purpose of the Study:

  • To review the mechanisms by which miRNAs regulate CD4+ T cell differentiation into Th17 cells in MS.
  • To explore the role of miRNAs in the pathophysiology of multiple sclerosis.
  • To identify potential miRNA targets for MS disease-modifying therapies.

Main Methods:

  • Literature review of studies on miRNAs, T helper cells, and multiple sclerosis.
  • Analysis of molecular mechanisms regulating T cell differentiation.
  • Identification of miRNA-gene interactions relevant to MS.

Main Results:

  • miRNAs play a crucial role in controlling the differentiation of CD4+ T cells towards the Th17 lineage.
  • Specific miRNAs are associated with disease activity, duration, and patterns in MS.
  • Dysregulation of miRNA pathways contributes to neuroinflammation in MS.

Conclusions:

  • miRNAs are significant regulators of Th17 cell differentiation in multiple sclerosis.
  • Targeting specific miRNAs offers a promising strategy for developing novel MS treatments.
  • Understanding miRNA-mediated pathways is essential for advancing MS therapeutics.

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

Regulation of Expression Occurs at Multiple Steps

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

B Cell Activation and Differentiation01:24

B Cell Activation and Differentiation

The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
