abstract = {Langerin/CD207 is expressed by a subset of dendritic cells (DC), the epithelial Langerhans cells. However, langerin is also detected among lymphoid tissue DC. Here, we describe striking differences in langerin-expressing cells between inbred mouse strains. While langerin+ cells are observed in comparable numbers and with comparable phenotypes in the epidermis, two distinct DC subsets bear langerin in peripheral, skin-draining lymph nodes of BALB/c mice (CD11c(high) CD8alpha(high) and CD11c(low) CD8alpha(low)), whereas only the latter subset is present in C57BL/6 mice. The CD11c(high) subset is detected in mesenteric lymph nodes and spleen of BALB/c mice, but is virtually absent from C57BL/6 mice. Similar differences are observed in other mouse strains. CD11c(low) langerin+ cells represent skin-derived Langerhans cells, as demonstrated by their high expression of DEC-205/CD205, maturation markers, and recruitment to skin-draining lymph nodes upon imiquimod-induced inflammation. It will be of interest to determine the role of lymphoid tissue-resident compared to skin-derived langerin+ DC.},

abstract = {The mononuclear phagocyte system of human lymphoid tissue comprises macrophages and dendritic cells (DCs). The heterogeneity of the non-DC mononuclear phagocyte population in human lymphoid tissue has been little addressed. Here, we studied the expression of 2 monocyte-derived markers, CD14 and CD169 (sialoadhesin), in reactive human lymphoid tissue as well as in a series of 51 B-cell lymphomas by immunohistochemistry on paraffin-embedded tissue. We confirmed that lymph node sinusoidal monocyte-derived cells were the only population staining for CD169. Although most sinusoidal histiocytes also expressed CD14, monocyte-derived cells with phagocytosis such as erythrophagocytosis, anthracosis, or tingible bodies macrophage lacked CD14 and CD169. Among B-cell lymphomas, splenic marginal zone lymphoma was the only one associated with an expansion of the CD14(+)CD169(+) cells in the cords. With respect to nodal B-cell lymphomas, CD14(+) cells were rare among B-chronic lymphocytic leukemia, follicular lymphoma (FL), mantle cell lymphoma (MCL). However, strikingly, we found a strong expansion of CD14(+)CD169(-) cells in numerous diffuse large B-cell lymphomas (DLBCLs), except in cases associated with numerous mitoses, apoptotic bodies, and tingible bodies macrophages. When cultivated in granulocyte/macrophage colony stimulating factor/interleukin 4, DLBCL purified CD14(+) cells differentiate into plasmacytoid cells, expressing DC-specific intercellular adhesion molecule 3-grabbing nonintegrin, suggesting dendritic cell differentiation potential. Our observation fits well with the lymph node and host response cluster signatures described in the gene profiling signatures of DLBCL. However, the role of this CD14(+) population that may constitute a microenvironment-related marker of this subgroup of DLBCL remains to be determined},

abstract = {Decysin, a gene encoding a disintegrin metalloprotease, is transcribed in human dendritic cells (DC) and germinal centers (GC). We have cloned its murine homologue and show that it is processed by the endoprotease furin before secretion of the catalytic domain. We have defined the cell types that express decysin in mouse spleen in the course of an immune response to T cell-dependent Ags. Like in humans, decysin is transcribed by activated CD11c(+) DC that enter the T cell zone from the marginal zone (MZ). In the GC, decysin is expressed by follicular DC and tingible body macrophages. In addition, a MZ cell population expresses decysin and appears to migrate into the B cell follicle. The majority of these follicle-homing cells express the mannose receptor ligand, a marker for the macrophage-like MZ metallophils. The follicle-homing cells are M-CSF dependent, as they are absent in op/op mice that lack functional M-CSF. This suggests that mannose receptor ligand(+) MZ metallophils differentiate into cells that migrate from the MZ into the B cell follicle. Decysin represents the first marker for this previously unrecognized cell population of the mouse spleen, which may represent a precursor for GCDC and may be specialized in the transport of unprocessed Ag from the MZ into developing GC.},
