CCL7 and hypohidrotic ectodermal dysplasia: Involvement of TAS2Rs was verified (i) by co-incubation of the PBMCs with PP and HED, which decreased (<i>p</i><0.01) the PP-induced secretion of CXCL9, CCL7, and CCL2 by a mean of 80%, 96%, and 95%, respectively, and (ii) via an siRNA knock-down approach targeting <i>TAS2R14</i>.
