Abstract:The specific mechanisms by which DCs initiate Th2 responses are not completely understood. We previously found that mice lacking the transcription factor IRF4 in DCs do not develop type 2 lung inflammation in response to house dust mite extract (HDM). Further, IRF4-deficient DCs had a reduced capacity for restimulating T cells towards a Th2 phenotype ex vivo. We hypothesized that IRF4 is necessary for DCs to perform one or more of the functions required to successfully initiate Th2 responses in vivo. Here we d… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
