T Cell Types and Functions

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...

Inflammatory Bowel Disease III: Crohn's Disease

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

The JAK-STAT Signaling Pathway

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...

Chronic Inflammation: Introduction

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...

Summary

This summary is machine-generated.

The single nucleotide polymorphism (SNP) rs6897932 in the IL7RA gene may increase the risk of developing chronic inflammatory arthropathies like rheumatoid arthritis. Further research is needed to confirm this association.

Area of Science:

Immunogenetics
Rheumatology
Genetics

Background:

The interleukin-7 receptor alpha chain (IL7RA) gene plays a role in immune system regulation.
A specific single nucleotide polymorphism (SNP), rs6897932, in IL7RA has been linked to autoimmune diseases like multiple sclerosis and Type I diabetes.

Purpose of the Study:

To investigate the association between 13 SNPs in the IL7RA gene and chronic inflammatory arthropathies.
To determine if rs6897932 is associated with rheumatoid arthritis and juvenile idiopathic arthritis.

Main Methods:

Genotyping of 13 SNPs within the IL7RA gene in 368 patients with chronic inflammatory arthropathies and 532 healthy controls.
Statistical analysis to assess the association between SNP genotypes and disease status.

Main Results:

No significant association was found for most IL7RA SNPs with chronic inflammatory arthropathies.
The TT genotype of the non-synonymous SNP rs6897932 was modestly enriched in patients with arthritic conditions compared to controls (P = 0.02; OR 1.72).

Conclusions:

The SNP rs6897932 in the IL7RA gene may play a role in the predisposition to chronic inflammatory arthropathies.
These findings suggest a potential genetic link between IL7RA and autoimmune arthritis.
