abstract：:In comparison to murine dendritic cells (DCs), less is known about the function of human DCs in tissues. Here, we analyzed, by using lung tissues from humans and humanized mice, the role of human CD1c(+) and CD141(+) DCs in determining the type of CD8(+) T cell immunity generated to live-attenuated influenza virus (LA...
