Inborn errors of immunity: A field without frontiers.

Area of Science:

• Immunology
• Genetics
• Human Physiology

Background:

• Primary immunodeficiencies (PIDs) are crucial for understanding immune system function.
• Historically focused on genetic causes and molecular pathways of infection-related conditions.
• The field has expanded beyond rare infections to include autoinflammation, autoimmunity, malignancy, and allergies.

Purpose of the Study:

• To highlight the evolving scope of inborn errors of immunity research.
• To demonstrate the expanding impact of PID studies across medical disciplines.
• To emphasize the link between understanding PIDs and developing targeted therapies.

Main Methods:

• Review of the progression of PID research.
• Analysis of diagnostic advancements in genetics.
• Integration of clinical observations across various medical fields.

Main Results:

• PID research has broadened from infection-focused phenotypes to diverse manifestations.
• Genetic diagnostics have enabled the study of a wider range of conditions.
• Impact is now seen in inflammatory bowel disease, neurology, and hematology.

Conclusions:

• Inborn errors of immunity research significantly advances fundamental immunology.
• Understanding PID genetics provides crucial insights into complex diseases.
• Identifying specific PIDs enables life-saving, targeted therapeutic strategies.
