Disabling the platelet's brakes to promote thrombosis.

In this issue of Blood, Magwenzi et al from the University of Hull report a novel mechanistic connection between oxidized low-density lipoprotein (oxLDL)-induced prothrombotic platelet signaling and the inhibition of endogenous platelet anti-activating signaling mediated by the nitric oxide (NO)/guanosine 3′,5′-cyclic monophosphate (cGMP)/protein kinase G (PKG) pathway.
