In this issue of Developmental Cell, Weinreb et al. reveal that loss of the DEAD-box helicase Ddx41 unexpectedly triggers an R-loop-mediated sterile inflammatory cascade which drives HSPC production during embryonic development. Human studies suggest mechanistic conservation for inflammation in DDX41-associated hematologic disease, uncovering a potential route for future therapeutic intervention.
