Summary
Regulatory T cells (Tregs) are crucial for immune tolerance. This review explores how Tregs, specifically CD4+ CD25+ cells, may contribute to rheumatoid arthritis, potentially leading to new therapies.
Area of Science:
- Immunology
- Autoimmunity
- Cellular Biology
Background:
- Regulatory T cells (Tregs) are essential for maintaining peripheral immune tolerance.
- Autoimmune diseases arise from a breakdown in immune tolerance.
- Understanding Treg function is key to developing treatments for autoimmune conditions.
Purpose of the Study:
- To review the role of naturally-occurring CD4+ CD25+ regulatory T cells in rheumatoid arthritis.
- To investigate the mechanisms by which Tregs may influence rheumatoid arthritis progression.
Main Methods:
- Literature review focusing on CD4+ CD25+ regulatory T cells.
- Analysis of existing research on Treg involvement in autoimmune diseases.
- Specific focus on rheumatoid arthritis pathogenesis.
Main Results:
- CD4+ CD25+ Tregs play a significant role in immune tolerance.
- Dysfunction or altered numbers of Tregs are implicated in the breakdown of tolerance seen in autoimmune diseases.
- Evidence suggests a potential involvement of these Tregs in the mechanisms of rheumatoid arthritis.
Conclusions:
- Regulatory T cells are critical players in immune homeostasis.
- Further understanding of CD4+ CD25+ Tregs in rheumatoid arthritis could reveal therapeutic targets.
- Targeting Tregs may offer a novel strategy for treating rheumatoid arthritis.

01:24T 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.

01:11Genome-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.

01:20The 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...
01:23Rheumatic 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...
01:24Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...
01:29Autoimmune Disorders
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.
