Article Title: Superior antigen cross-presentation and XCR1 expression define human CD11c + CD141 + cells as homologues of mouse CD8 + dendritic cells

doi: 10.1084/jem.20100348

Figure Lengend Snippet: XCL1 induces a [Ca 2+ ] i signal in CD141 + DCs. CD141 + DCs were flow sorted to a purity >98.7%, immobilized on poly– l -lysine–coated glass coverslips, and loaded with 2 µM fura-2/AM. Cells were imaged in a monochromator-assisted digital video imaging system and challenged with 1 µg/ml XCL1 as indicated (left arrow). Subsequently, the same cells were challenged again with a mixture of 100 ng/ml CCL2, 200 ng/ml CCL21, 200 ng/ml CXCL9, and 1 ng/ml CX3CL1 used as a positive control (right arrow). The data shown represent [Ca 2+ ] i concentrations of 300 single cells (gray lines) measured in two independent experiments. The mean [Ca 2+ ] i signal averaged over all cells responding to XCL1 is indicated (black line).

Article Snippet: The lower chamber was filled with chemotaxis medium containing recombinant human XCL1 (R&D Systems) or any of the chemokines CCL2 (100 ng/ml), CCL21 (200 ng/ml), CX3CL1 (1 ng/ml), CXCL12 (200 ng/ml for T cells, B cells, NK cells, and monocytes; 100 ng/ml for pDCs), and CXCL8 (100 ng/ml; all from R&D Systems), and the cells were incubated for 150 min at 37°C in 5% CO 2 .

Figure Lengend Snippet: XCL1 selectively induces chemotaxis in CD141 + DCs. (A) A mixture of highly purified, flow-sorted DC subtypes (20% CD141 + , 40% CD16 + , and 40% CD1c + DCs; Input DC) was tested for migration in response to medium alone or to serial dilutions of XCL1 (10–5,000 ng/ml) in a Transwell system. A combination of the chemokines CCL2, CCL21, and CX3CL1 was used as a positive control for the DC subsets (Migrated DC). The absolute numbers of CD141 + , CD1c + , and CD16 + DCs in input and migrated cell populations are truly represented in the dot plots, because all cells within a defined volume were included in the analysis in each instance. (B) Proportion of migrated CD1c + , CD16 + , and CD141 + DCs in the experiment shown in A. (C) Proportion of migrated pDCs, monocytes, granulocytes, T cells, B cells, and NK cells in response to XCL1 (10–1,000 ng/ml) or the chemokines CXCL12 and CXCL8, which were used as positive controls. For migration assays of B cells, NK cells, and monocytes, PBMCs were magnetically depleted of T cells, and for T cell migration, PBMCs were used directly. For migration assays of granulocytes, whole blood cells were used after erythrocyte lysis with ACK buffer, and pDCs were magnetically enriched from PBMCs with the Plasmacytoid Dendritic Cell Isolation Kit (Miltenyi Biotec). All experiments with DCs were performed three times; all other populations were assayed twice. Error bars represent means ± SEM.

Figure Lengend Snippet: Involvement of the XCL1–XCR1 communication axis in the innate and adaptive cytotoxic responses to cross-presented microbial and tumor antigens. Secretion of the chemokine XCL1 by activated NK cells specifically attracts XCR1-expressing DCs capable of antigen cross-presentation. This ensures an effective communication between these cells in the innate phase of the immune response. In the adaptive phase, secretion of XCL1 by activated CD8 + T cells optimizes the communication with antigen cross-presenting DCs and facilitates the differentiation of CD8 + T cells to cytotoxic cells.

Figure Lengend Snippet: Figure 2. Flow cytometric analysis results of XCL1 expression. PBMC isolated from WG patients and healthy controls were subjected to flow cytometric analysis after stimulation with PMA/ionomycin. XCL1 was expressed in a significantly greater proportion of CD4+ and CD8+ T cells in WG patients in comparison to controls (A). XCL1 was detected in WG patients in a significantly greater proportion of CD4+ T cells lacking the costimulatory molecule CD28 (p = 0.007) (B). In CD8+ T cells, XCL1 expression was found mainly within the CD8+CD28– T cell subpopulation in WG patients, but there was no statistically significant difference of frequencies of XCL1-expressing CD8+CD28– T cells between WG patients and controls (C). Comparing T cells from patients with active and inactive WG, a significant difference was detected between these patient groups in frequencies of XCL1-positive CD4+ T cells and CD8+ T cells (p < 0.001) (D).

Article Snippet: Cells were subsequently stimulated with human recombinant XCL1 (R&D Systems, Wiesbaden, Germany) at a concentration of 100 ng/ml for 24 h. To control the specificity of XCL1 action, anti-human XCL1 antibody (R&D Systems) was added to the control wells.
