This review explores how dendritic cells (DCs) and regulatory T cells (Tregs) maintain self-tolerance. It highlights their interactions and potential therapeutic targets for immune tolerance.
Area of Science:
- Immunology
- Cell Biology
- Autoimmunity
Background:
- Self-tolerance is crucial for preventing autoimmune diseases.
- Dendritic cells (DCs) and regulatory T cells (Tregs) are key players in immune regulation.
- Understanding their interplay is vital for developing new therapies.
Purpose of the Study:
- To review mechanisms of self-tolerance.
- To examine the roles of DCs and Tregs in maintaining tolerance.
- To discuss technological advances and therapeutic targets for tolerance induction.
Main Methods:
- Literature review of immunological mechanisms.
- Analysis of cellular interactions (DCs and Tregs).
- Survey of technological and therapeutic prospects.
Main Results:
- DCs and Tregs collaborate to sustain antigen-specific tolerance.
- B-cell tolerance and hematopoietic cell chimerism are important factors.
- Cosignaling pathways significantly impact tolerance induction.
Conclusions:
- Interplay between DCs and Tregs is essential for self-tolerance.
- Technological advancements offer new ways to monitor and predict tolerance.
- Novel therapeutic targets for promoting tolerance are emerging.

Special Features of Adaptive Immunity
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,...

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature is...
