Insights

This study found that the full-length Mediterranean fever (MEFV) gene is downregulated in early-stage rheumatoid arthritis (RA) patients. This reduced MEFV-fl expression may contribute to RA pathogenesis and inflammation.

Area of Science:

  • Immunology
  • Genetics
  • Rheumatology

Background:

  • Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by T cell activation and inflammation.
  • The Mediterranean fever (MEFV) gene, encoding pyrin, is linked to RA severity, but its specific role in pathogenesis remains unclear.

Purpose of the Study:

  • To investigate the expression of the full-length MEFV gene (MEFV-fl) and its exon 2-deleted splice isoform (MEFV-d2) in rheumatoid arthritis patients.
  • To determine if MEFV gene expression is associated with RA clinical conditions.

Main Methods:

  • Quantitative real-time polymerase chain reaction (RT-qPCR) was used to analyze MEFV gene expression in peripheral blood samples.
  • The study included 47 RA patients and 47 age- and gender-matched healthy controls.

Main Results:

  • Downregulation of MEFV-fl mRNA was observed in non-treated RA patients compared to healthy controls and treated patients.
  • No significant difference in MEFV-d2 expression was found between the groups.

Conclusions:

  • This is the first study to examine MEFV transcript expression in RA.
  • Downregulation of MEFV-fl may play a role in the pathogenesis of early-stage RA.
  • Therapeutic interventions might ameliorate MEFV-fl expression in RA patients.

Master Transcription Regulators02:23

Master Transcription Regulators

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

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...

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

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...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
