Insights

Rheumatoid arthritis (RA) involves joint tissue damage. MicroRNAs, like miR-146a, are increasingly recognized for their role in RA pathogenesis and as potential biomarkers for diagnosis and therapy.

Area of Science:

  • Immunology
  • Molecular Biology
  • Genetics

Background:

  • Rheumatoid arthritis (RA) is a chronic autoimmune disease impacting joints, bone, and cartilage.
  • The precise mechanisms driving RA pathogenesis remain incompletely understood.
  • Established biomarkers include rheumatoid factor and anti-cyclic citrullinated peptide antibodies.

Purpose of the Study:

  • To explore the significance of microRNAs in rheumatoid arthritis (RA) pathogenesis.
  • To evaluate microRNAs as potential biomarkers for RA diagnosis and monitoring.
  • To investigate microRNAs as possible therapeutic targets for RA.

Main Methods:

  • Review of current literature on microRNA expression in RA.
  • Analysis of studies investigating the role of specific microRNAs (e.g., miR-146a) in RA.
  • Examination of diagnostic and prognostic potential of microRNAs in RA patients.

Main Results:

  • MicroRNA expression patterns are altered in various cell types and tissues of RA patients.
  • Upregulation of miR-146a observed in RA patients.
  • MicroRNAs show promise as biomarkers for RA activity and prognosis.

Conclusions:

  • MicroRNAs play a significant role in the pathogenesis of rheumatoid arthritis.
  • Specific microRNAs, such as miR-146a, are potential biomarkers for RA.
  • MicroRNAs represent promising targets for future RA therapeutic strategies.

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

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 the pre-miRNA ends...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
T Cell Types and Functions01:24

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...
