Summary
The epigenome, including microRNAs (miRNAs), offers insights into autoimmune disease origins. Epigenetic deregulation, particularly miRNA activity, is crucial in rheumatic autoimmune disorders, guiding future research.
Area of Science:
- Immunology
- Genetics
- Molecular Biology
Background:
- The causes of autoimmune diseases are not fully understood.
- Epigenetic factors, beyond genetics, are increasingly implicated in autoimmunity.
- Epigenetic mechanisms regulate gene expression and cellular responses.
Purpose of the Study:
- To review epigenetic deregulations in rheumatic autoimmune disorders.
- To highlight the specific role of microRNAs (miRNAs) in autoimmunity.
- To explore the epigenome's contribution to disease initiation and progression.
Main Methods:
- Literature review of epigenetic mechanisms in autoimmune diseases.
- Focus on DNA methylation, histone modifications, and miRNA activity.
- Analysis of miRNA's role in rheumatic autoimmune conditions.
Main Results:
- Epigenetic deregulation is frequently observed in rheumatic autoimmune disorders.
- MicroRNAs play a significant role in the pathogenesis of these conditions.
- Epigenetic modifications influence gene and protein expression relevant to autoimmunity.
Conclusions:
- Epigenetic mechanisms, especially miRNAs, are critical in rheumatic autoimmune diseases.
- Understanding epigenetic alterations can lead to new therapeutic strategies.
- Further research into miRNA's function is essential for unraveling autoimmunity.

Autoimmune 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.

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.

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.

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...
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...
