Cell Deletion:

Deletion of Jun and JunB was verified by PCR. Similarly, 300 ng of Diphtheria toxin (DT, List Biological Laboratories, in PBS) was injected intraperitoneally into experimental mice according to the schemes indicated in the figures. For LC depletion, DT was applied every third day, and for pDC depletion, every other day.
