Summary
Autoimmune dysfunction may play a role in Tourette syndrome (TS) and related childhood-onset neurological disorders. This review updates evidence on immune dysfunction in TS, exploring clinical and genetic studies.
Area of Science:
- Neuroscience
- Immunology
- Genetics
Background:
- Tourette syndrome (TS) and chronic tic disorder are common childhood-onset neurological conditions with unclear pathophysiology.
- Current research often focuses on the corticostriatal-thalamocortical circuit, but autoimmune dysfunction is an emerging area of investigation.
- Autoimmune mechanisms are also implicated in related disorders like obsessive-compulsive disorder, autism, and ADHD.
Purpose of the Study:
- To review and update the understanding of immune dysfunction in the pathogenesis of Tourette syndrome.
- To consolidate evidence from clinical, genetic, in vitro, and animal studies.
- To explore the potential role of autoimmune processes in TS and related neuropsychiatric conditions.
Main Methods:
- Systematic review of existing literature.
- Analysis of clinical characteristics and findings related to immune markers in TS.
- Evaluation of genetic studies, in vitro experiments, and animal models investigating immune involvement.
Main Results:
- Evidence suggests a potential link between autoimmune dysfunction and Tourette syndrome.
- Clinical and genetic studies provide support for immune system involvement in TS.
- Animal models and in vitro studies offer further insights into pathogenetic mechanisms.
Conclusions:
- Autoimmune dysfunction is a plausible contributing factor to the pathophysiology of Tourette syndrome.
- Further research integrating immunological, genetic, and clinical data is warranted.
- Understanding immune mechanisms may lead to novel therapeutic strategies for TS and related disorders.

Disorders of the Nervous Tissue

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

Immunodeficiency Diseases
1.5K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

T Cell Types and Functions
1.8K
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.

Autoimmune Disorders
1.1K
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 Activation and Clonal Selection
14.1K
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.
