Accessory cells with immunophenotypic and functional features of monocyte-derived dendritic cells are recruited to the lung during pulmonary inflammation.

abstract：:LPS induces dendritic cell (DC) activation, but the precise in vivo mechanism is unclear since DCs express low levels of TLR4. Here, it is shown that DCs can be activated in response to LPS through a bystander mechanism. This result was obtained using chimeric mice reconstituted with LPS-responsive and nonresponsive b...
