The anti-inflammatory role of heme oxygenase-1 (HO-1) has been studied
extensively in many disease models including asthma. Many cell types are
anti-inflammatory targets of HO-1, such as dendritic cells and regulatory T
cells. In contrast to previous reports that HO-1 had limited effects on
basophils, which participate in T helper type 2 immune responses and
antigen-induced allergic airway inflammation, we demonstrated in this study, for
the first time, that the up-regulation of HO-1 significantly suppressed the
maturation of mouse basophils, decreased the expression of CD40, CD80, MHC-II and
activation marker CD200R on basophils, blocked DQ-ovalbumin uptake and promoted
basophil apoptosis both in vitro and in vivo, leading to the inhibition of T
helper type 2 polarization. These effects of HO-1 were mimicked by exogenous
carbon monoxide, which is one of the catalytic products of HO-1. Furthermore,
adoptive transfer of HO-1-modified basophils reduced ovalbumin-induced allergic
airway inflammation. The above effects of HO-1 can be reversed by the HO-1
inhibitor Sn-protoporphyrin IX. Moreover, conditional depletion of basophils
accompanying hemin treatment further attenuated airway inflammation compared with
the hemin group, indicating that the protective role of HO-1 may involve multiple
immune cells. Collectively, our findings demonstrated that HO-1 exerted its
anti-inflammatory function through suppression of basophil maturation and
activation, but promotion of basophil apoptosis, providing a possible novel
therapeutic target in allergic asthma.
