Highlight of 2023: Advances in pediatric immunology.

ABSTRACT

In this article for the Highlights of 2023 Series, significant advancements in pediatric immunology are discussed, focusing on new diagnostic and therapeutic approaches. Key studies include the integration of genomic and proteomic profiling for better diagnosis of inborn errors of immunity, the impact of nongenetic factors such as autoantibodies on immune responses, the promising use of Janus kinase inhibitors and chimeric antigen receptor-T cell therapy for treating immune deficiencies and autoimmune diseases and the potential for a curative approach using prime editing. These developments mark a shift toward personalized and precision medicine in pediatric immunology.
