BRAF-V600E expression in precursor versus differentiated dendritic cells defines clinically distinct LCH risk groups.

2014

BRAF-V600E expression is identified in hematopoietic progenitor and precursor myeloid dendritic cells in patients with high-risk LCH, and enforced expression of BRAF-V600E in CD11c+ cells recapitulates a high-risk LCH-like phenotype in mice.

Topoisomerase 1 inhibition suppresses inflammatory genes and protects from death by inflammation

2015

Unwinding DNA and unleasing inflammation Fighting infections often comes with collateral damage, which sometimes can be deadly. For instance, in septic shock, the overwhelming release of inflammatory mediators drives multi-organ failure. Rialdi et al. now report a potential new therapeutic target for controlling excessive inflammation: the DNA unwinding enzyme topoisomerase I (Top1) (see the Perspective by Pope and Medzhitov). Upon infection, Top1 specifically localizes to the promoters of pathogen-induced genes and promotes their transcription by helping to recruit RNA polymerase II. Pharmacological inhibition of Top1 in a therapeutic setting increased survival in several mouse models of s…
