Abstract

In the skin, the lack of markers permitting the unambiguous identification of macrophages and of conventional and monocyte-derived dendritic cells (DCs) complicates understanding of their contribution to skin integrity and to immune responses. By combining CD64 and CCR2 staining, we successfully identified each of these cell types and studied their origin, transcriptomic signatures, and migratory and T cell stimulatory properties. We also analyzed the impact of microbiota on their development and their contribution to skin inflammation during contact hypersensitivity. Dermal macrophages had a unique scavenging role and were unable to migrate and activate T cells. Conventional dermal DCs excelled both at migrating and activating T cells. In the steady-state dermis, monocyte-derived DCs are continuously generated by extravasated Ly-6C(hi) monocytes. Their T cell stimulatory capacity combined with their poor migratory ability made them particularly suited to activate skin-tropic T cells. Therefore, a high degree of functional specialization occurs among the mononuclear phagocytes of the skin.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
