Inborn errors in immunity reveal critical roles for the interleukin-17 (IL-17) pathway in oral health. Genetic defects illuminate immune functions and susceptibility to fungal infections and inflammatory periodontitis.
Area of Science:
- Immunology
- Genetics
- Oral Health
Background:
- Inborn errors in immunity (IEI) studies have identified novel immune system genes.
- Genomics advancements accelerate the discovery of genetic defects.
- Naturally occurring mutations offer mechanistic insights into human immune function.
Purpose of the Study:
- To discuss how IEI serve as models for understanding human biology and common diseases.
- To highlight the role of the interleukin-17 (IL-17) pathway in oral mucosal immunity.
Main Methods:
- Review of emerging evidence on IEI.
- Analysis of genetic disruptions in patients.
- Focus on the IL-17 axis in oral immune surveillance.
Main Results:
- IEI provide critical insights into human biology and common diseases like those affecting oral health.
- The IL-17 pathway is crucial for oral immune surveillance.
- Disruptions in the IL-17 axis are linked to fungal susceptibility.
- Overactivation of IL-17 pathways is associated with inflammatory periodontitis.
Conclusions:
- IEI are invaluable models for understanding immune system function and disease.
- The IL-17 pathway is a key player in oral health, influencing susceptibility to infections and inflammatory conditions.
- Understanding IL-17 in IEI can inform strategies for managing oral diseases.

Introduction to Innate and Adaptive Immunity
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...
Defense Mechanism Against Infection
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...
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...

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,...
