Biological Description of 109 Cases of Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN) from the French Network of BPDCN
2015
Abstract Blastic plasmacytoid dendritic cell neoplasm is a clonal disease derived from precursors of plasmacytoid dendritic cells (pDC). It is a rare neoplasm involving the skin which may or may not be associated from the outset with a leukemic component. The disease invariably progresses to aggressive leukemic dissemination, leading to a differential diagnosis with acute leukemia. In 2004, we set up a French network to recruit biological data at diagnosis. Diagnosis was according to recommendations (Swerdlow et al, 2008), with, in addition, a mandatory panel of pDC markers (Garnache-Ottou et al, 2009) detected by flow cytometry or by immunohistochemistry on infiltrated blood, bone marrow o…
LXR agonist treatment of blastic plasmacytoid dendritic cell neoplasm restores cholesterol efflux and triggers apoptosis
2016
International audience; Blastic plasmacytoid dendritic cell (PDC) neoplasm (BPDCN) is an aggressive hematological malignancy with a poor prognosis that derives from PDCs. No consensus for optimal treatment modalities is available today and the full characterization of this leukemia is still emerging. We identified here a BPDCN-specific transcriptomic profile when compared with those of acute myeloid leukemia and T-acute lymphoblastic leukemia, as well as the transcriptomic signature of primary PDCs. This BPDCN gene signature identified a dysregulation of genes involved in cholesterol homeostasis, some of them being liver X receptor (LXR) target genes. LXR agonist treatment of primary BPDCN …
