Challenges and future directions of AIRR-seq-based diagnostics

Area of Science:

• Immunology
• Genomics
• Bioinformatics

Background:

• Adaptive Immune Receptor Repertoire sequencing (AIRR-seq) is a powerful tool for analyzing immune system responses.
• Clinical implementation of AIRR-seq is hindered by several significant challenges.
• Standardization and data interpretation remain critical barriers to widespread adoption.

Purpose of the Study:

• To examine the current state of AIRR-seq diagnostics.
• To identify key obstacles and opportunities for advancing AIRR-seq implementation.
• To discuss the potential of AIRR-seq in precision medicine.

Main Methods:

• Review of current AIRR-seq diagnostic landscape.
• Analysis of challenges including quality control, data privacy (GDPR, HIPAA), and bioinformatics.
• Exploration of machine learning applications for repertoire signature interpretation.

Main Results:

• Standardized quality controls, robust privacy measures, and clinically compatible bioinformatics pipelines are essential.
• Machine learning can aid interpretation but requires a balance between accuracy and clinical interpretability.
• Future applications include early disease detection, prognosis, and treatment/vaccine response monitoring.

Conclusions:

• Successful clinical integration of AIRR-seq necessitates collaboration among stakeholders (funding bodies, regulators, researchers, clinicians).
• Establishing clear guidelines and expanding well-characterized patient sample repositories are crucial.
• Ongoing initiatives aim to unlock AIRR-seq's potential in precision medicine and diagnostics.
