Review Series: Cytokines as therapeutic targets: Insights from clinical interventions

The advent of molecularly targeted therapies has fundamentally changed our understanding of allergic diseases. Beyond expanding treatment options, these therapies allow us to explore human disease in vivo by selectively targeting a single molecule and clarifying its role within complex immune networks. We hope that this series will offer useful insights for clinicians and researchers, serving as a reminder that the results of therapeutic intervention can help elucidate the fundamental biology of allergic disease.
