Pathogenesis of rheumatoid arthritis
1From the Department of Medicine (Rheumatology), Biotechnology Study Center, New York University School of Medicine, New York, NY.
Summary
Immune complexes are the likely cause of rheumatoid arthritis (RA) tissue damage. These complexes activate immune cells, leading to inflammation and joint destruction in RA pathogenesis.
Area of Science:
- Immunology
- Rheumatology
- Pathogenesis Research
Background:
- Rheumatoid arthritis (RA) involves diverse tissue damage mechanisms.
- Immune complexes are strongly implicated as the underlying cause of RA.
- Specific autoantibodies, like those against citrullinated peptides, may be key RA markers.
Purpose of the Study:
- To review recent advancements in understanding RA pathogenesis.
- To elucidate the role of immune complexes in RA development.
- To highlight key inflammatory pathways in rheumatoid arthritis.
Main Methods:
- Review of existing literature on rheumatoid arthritis pathogenesis.
- Analysis of immune complex formation and function in RA.
- Examination of inflammatory mediator cascades in joint destruction.
Main Results:
- Self-aggregating 7s rheumatoid factor complexes in synovial fluid are characteristic of RA.
- Circulating 19s rheumatoid factor complexes and anti-citrullinated peptide antibodies are associated with RA.
- Immune complexes trigger complement activation and phagocyte stimulation, releasing inflammatory mediators.
Conclusions:
- Immune complexes are central to rheumatoid arthritis pathogenesis.
- Complement activation and Fc receptor stimulation by immune complexes drive inflammation.
- Cytokines, metalloproteinases, and reactive oxygen species contribute to joint destruction in RA.

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...
01:24T 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.

01:20The 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...
01:29Autoimmune 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.

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.

01:22Rheumatic 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...
