TSLP and asthma: Epithelial cell‐derived TSLP stimulates various aspects of basophil functions including, at least in part, basophil activation in asthma patients, in addition to other important epithelial cytokines (alternatively spliced variants of IL‐33 and IL‐25).98, 99 Furthermore, it has recently been shown that in vitro TSLP‐primed basophil migrate to CCL11 chemokine by upregulation of CCR3 expression.98
