Increased Proportion of Dual-Positive Th2–Th17 Cells Promotes a More Severe Subtype of Asthma

Asthma is a heterogeneous disease, and abnormal activation of T cells is the driving link of asthma's pathophysiological changes. Dual-positive Th2-Th17 cells, as newly discovered T-helper cells, have the functions of Th2 and Th17 cells and can coproduce Th2 and Th17 cytokines. Previous studies have shown that dual-positive Th2-Th17 cells increase the chances of asthma and correlate with asthma severity. However, the exact role of dual-positive...
