AML is characterized by excessive proliferation and infiltration of neoplastic cells of hematopoietic origin. AML occurs at a median age of 67 and will lead to an estimated 10,460 deaths in the United States in 2014. Therapy for AML has changed little in the last 30 years, and consists of an induction regimen of cytotoxic chemotherapy, followed by consolidation therapy and hematopoietic stem ce...
Innate lymphoid cells (ILC) are members of a heterogeneous family with a lymphoid origin that mimics the T helper (Th) cytokine profile. ILC are involved in early effector cytokine-mediated responses during infections in peripheral tissues. ILC also play an important role in chronic skin inflammatory diseases, including psoriasis. Although classical ILC express CD127, it has been recently repor...
BACKGROUND Leukemic stem cells (LSCs) are frequently seen as a cause of treatment failure and relapse in patients with acute myeloid leukemia (AML). Thus, successful new therapeutic strategies for the treatment of AML should aim at eradicating LSCs. The identification of targets on the cell surface of LSCs is getting more and more attention. Among these, CD123, also known as the interleukin-3 (...
Loss of circulating CD123+ plasmacytoid dendritic cells (pDCs) during HIV infection is well established. However, changes of myeloid DCs (mDCs) are ambiguous since they are studied as a homogeneous CD11c+ population despite phenotypic and functional heterogeneity. Heterogeneity of CD11c+ mDCs in primates is poorly described in HIV and SIV infection. Using multiparametric flow cytometry, we moni...
Distinct subsets of dendritic cells (DCs) are present in blood, probably "en route" to different tissues. We have investigated the chemokines and adhesion molecules involved in the migration of myeloid (CD11c(+)) and plasmacytoid (CD123(+)) human peripheral blood DCs across vascular endothelium. Among blood DCs, the CD11c(+) subset vigorously migrated across endothelium in the absence of any ch...
PURPOSE We evaluated leukemia-associated immunophenotypes (LAIP) and their correlation with fms-like tyrosine kinase 3 (FLT3) and nucleophosmin (NPM1) gene mutational status in order to contribute a better identification of patients at highest risk of relapse in acute myeloid leukemia (AML). EXPERIMENTAL DESIGN Bone marrow samples from 132 patients with AML were analyzed by nine-color multipa...
Changes in blood dendritic cell (BDC) counts (CD123(hi)BDC and CD11c(+)BDC) and expression of CD62L, CCR7, and CD49d were analyzed in healthy donors, multiple myeloma (MM), and non-Hodgkin lymphoma (NHL) patients, who received granulocyte-colony stimulating factor (G-CSF) containing peripheral blood stem cell (PBSC) mobilization protocols. Low-dose G-CSF in healthy donors (8-10 microg/kg/d subc...
AIMS Squamous cell carcinoma of the skin (SCC) increases dramatically in organ transplant recipients (OTRs). The aim was to determine whether qualitative and quantitative differences in perineoplastic inflammation in OTRs contribute to the increased carcinogenesis. METHODS AND RESULTS We studied the perineoplastic inflammatory infiltrate in SCC, assessing depth, density and phenotype (CD3, 4,...
© 2014 The Authors. doi: 10.2340/00015555-1777 Journal Compilation © 2014 Acta Dermato-Venereologica. ISSN 0001-5555 Lupus erythematosus profundus is a rare inflammatory disorder of subcutaneous fat in patients with lupus ery thematosus. Previous reports suggested that plasmacy toid dendritic cells, which expressed CD123 and CD303 antigens, play a central proinflammatory role in the patho gen...
We have previously described enrichment of antigen-presenting HLA-DR+ nuclear RelB+ dendritic cells (DCs) in rheumatoid arthritis (RA) synovium. CD123+HLA-DR+ plasmacytoid DCs (pDCs) and their precursors have been identified in human peripheral blood (PB), lymphoid tissue, and some inflamed tissues. We hypothesized recruitment of pDCs into the inflamed RA synovial environment and their contribu...
