Autoimmune Disorders

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.

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...

T Cell Activation and Clonal Selection

T Cell Activation and Clonal Selection

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
Naive T cells that have not yet encountered an antigen express two primary CD...

Special Features of Adaptive Immunity

Special Features of Adaptive Immunity

The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

Diversity of Antigen Receptors

Diversity of Antigen Receptors

Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

Autoimmunity Reviews

|January 15, 2008

Summary

Toll-like receptors (TLRs) are key players in autoimmune diseases like systemic lupus erythematosus (SLE). Recent findings show TLRs 7, 8, and 9 detect host molecules, driving autoimmune conditions.

Area of Science:

Immunology
Pathophysiology
Molecular Biology

Background:

Autoimmune diseases are increasingly understood with the identification of Toll-like receptors (TLRs).
TLRs are crucial in initiating immune responses against pathogens.
Emerging data highlight TLRs' role in the development and progression of autoimmune disorders, particularly systemic lupus erythematosus (SLE).

Purpose of the Study:

To review recent findings on the involvement of TLRs in autoimmune disease pathogenesis.
To focus on Toll-like receptors 7, 8, and 9 and their specific roles.

Main Methods:

Review of current in vitro and in vivo studies.
Analysis of literature on TLRs 7, 8, and 9 in autoimmunity.

Main Results:

TLRs are implicated in the induction and perpetuation of autoimmune diseases.
TLRs 7, 8, and 9, initially known for detecting microbial nucleic acids, are now linked to recognizing self-derived molecules.
These receptors can detect host RNA, DNA, and associated proteins in autoimmune contexts.

Conclusions:

TLRs play a significant role in the pathophysiology of autoimmune diseases.
The recognition of self-nucleic acids and associated proteins by TLRs 7, 8, and 9 contributes to autoimmunity.
Further research into TLRs offers potential therapeutic targets for autoimmune conditions like SLE.
