Summary
The ontogeny of native Langerhans cells (LCs) in the epidermis has been debated over the past decade, with most agreeing that such LCs are now best classified as specialized resident-tissue macrophages derived from the embryonic yolk sac that have a self-renewal capacity in the steady state, along with migratory dendritic cell (DC)–like properties (albeit with much slower migration as compared to conventional or classic DCs [cDCs]) (1). The diversity of the epidermal pool of resident and inflammatory macrophages and DCs may be greater than previously realized – with LCs, monocyte-derived LC-like cells, and inflammatory dendritic epidermal cells (IDECs) all acting as human antigen-presenting cells (1).
