Due to the authors’ carelessness, we used mistakenly PBMCs isolated from same patient in Fig. 1a for P2X3 immunoreactivity in VI: PUE-treated group on the second day (Third row middle graph) and VII: PUE-treated on the third day (Third row right- side graph).

Fig. 1 Effect of puerarin on the expression of P2X3 receptors in peripheral blood mononuclear cells (PBMCs) by immunohistochemistry. a I: healthy volunteers (control); II: normal saline (NS)-treated group on the first day; III: NS-treated group on the second day; IV: NS-treated group on the third day; V: puerarin (PUE)-treated group on the first day; VI: PUE-treated group on the second day; VII: PUE-treated on the third day. (Arrows indicate the immunostaining of PBMCs; scale bars, 20 μm)
