Research Abstract

Dendritic cells (DCs) play critical roles in determining the fate of CD4+ T cells. While previous studies have shown that CD11c+ DCs play an indispensable role in the induction of allergic airway inflammation and airway hyperreactivity (AHR) in murine asthma models, the precise roles of monocyte-derived inflammatory DCs (iDCs) in the asthmatic responses remain largely unknown. We show here that Th2 cell-mediated inflammation in murine asthma models instructs iDCs to express a part of alternatively-activated macrophage markers arginase 1 by a mechanism depending on the intrinsic expression of STAT6. Moreover, we show that iDCs under a Th2 environment play a critical role in the induction of AHR independently of allergic airway inflammation. Our results thus indicate the importance of iDCs in the induction of AHR as downstream effector cells inTh2 cell-mediated asthmatic responses.
