Developing immune tolerance therapies aims to restore immune system regulation for autoimmune disorders. Key challenges include selecting disease models, safety assessments, biomarkers, and regulatory guidelines for drug development.
Area of Science:
- Immunology and Pharmacology
- Drug Development and Regulatory Science
Background:
- Immune tolerance is crucial for preventing autoimmune diseases, characterized by immune unresponsiveness to self-antigens.
- Loss of immune tolerance leads to autoantibodies, tissue injury, and autoimmune conditions.
- Emerging immune tolerance therapies aim to restore immune system regulation for treating autoimmune disorders.
Purpose of the Study:
- To review the significant challenges in developing pharmaceutical drugs that induce immune tolerance.
- To outline critical steps from preclinical efficacy in animal models to human translation for tolerance therapies.
Main Methods:
- Discussion of challenges in selecting appropriate animal models for establishing pharmacological efficacy.
- Review of essential in vitro and in vivo safety assessment strategies.
- Identification of relevant biomarkers for human safety and therapeutic efficacy.
Main Results:
- The review highlights the complexity of translating preclinical findings to human applications.
- It emphasizes the need for robust safety evaluations and predictive biomarkers.
- Regulatory guidelines are crucial for successful development of immune tolerance therapeutics.
Conclusions:
- Developing effective immune tolerance therapeutics requires overcoming significant hurdles in preclinical and clinical development.
- Addressing challenges in model selection, safety, biomarkers, and regulatory pathways is essential for advancing these treatments.

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...
