Elevated levels of circulating <scp>CD</scp>4⁺<scp>CRT</scp>h2⁺ T cells characterize severe asthma

Abstract

Elevated levels of circulating CD4(+) CRTh2(+) T cells are a feature of severe asthma, despite high-dose corticosteroids. Tracking the systemic level of these cells may help identify type 2 severe asthmatics at risk of exacerbation.
