Atherosclerosis is the most common cardiovascular disease in Europe and North America. The c-Jun N-terminal kinase (JNK) family is implicated in atherogenesis. Ricci et al. addressed the function of JNK in atherogenesis, using atherosclerosis-prone apolipoprotein E (ApoE)-deficient mice simultaneously lacking either JNK1 or JNK2. JNK2 deletion strikingly reduced plaque formation in ApoE-deficient mice. However, deletion of JNK1 revealed only a slight effect on atheroma formation. Pharmacological inhibition of overall JNK activity substantially suppressed atherosclerosis in ApoE-deficient mice. Specific inhibition of JNK2 activity may thus represent a therapeutic approach to ameliorate atherosclerosis.
