SlanDCs/M-DC8+ cells constitute a distinct subset of dendritic cells in human tonsils [corrected].

ABSTRACT: Human blood dendritic cells (DCs) include three main distinct subsets, namely the CD1c+ and CD141+ myeloid DCs (mDCs) and the CD303+ plasmacytoid DCs (pDCs). More recently, a population of slan/M-DC8+ cells, also known as "slanDCs", has been described in blood and detected even in inflamed secondary lymphoid organs and non-lymphoid tissues. Nevertheless, hallmarks of slan/M-DC8+ cells in tissues are poorly defined. Herein, we report a detailed characterization of the phenotype and function of slan/M-DC8+ cells present in human tonsils. We found that tonsil slan/M-DC8+ cells represent a unique DC cell population, distinct from their circulating counterpart and also from all other tonsil DC and monocyte/macrophage subsets. Phenotypically, slan/M-DC8+ cells in tonsils display a CD11c+HLA-DR+C
