LAG-3 Regulates Plasmacytoid Dendritic Cell Homeostasis

DAP12 signaling regulates plasmacytoid dendritic cell homeostasis and down-modulates their function during viral infection.

DAP12 is an ITAM-containing adaptor molecule conveying activating properties to surface receptors on many cell types. We show here that DAP12 paradoxically down-modulates plasmacytoid dendritic cell (pDC) cytokine production in vivo during murine CMV (MCMV) infection. Higher levels of IFN-alphabeta and IL-12 were detected upon MCMV infection or CpG treatment in DAP12-deficient (DAP12(o)) mice a...

Blastic Plasmacytoid Dendritic Cell Neoplasm; A Report of Three Cases

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematodermic myeloid malignancy that is known to be derived from plasmacytoid dendritic cells which are characterized by expression of CD4, CD56, and more specific markers such as CD123. Here, the authors present three cases of BPDCN diagnosed in the past two years and address different available diagnostic modalities such as morpho...

Blastic Plasmacytoid Dendritic Cell Neoplasm

Introduction Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare, highly aggressive hematopoietic malignancy. It manifests as cutaneous and bone marrow involvement and leukemic spread. It represents 0.7% of primary cutaneous lymphomas. Recently, it was established as a distinct entity. We present a rare case of BPDCN with good response to chemotherapy and review the clinicopathologic...
