Acetaldehyde was shown to alter cellular respiration in cultured microvascular endothelial hBMVEC cells, which mainly comprise the bloodbrain-barrier, thereby suggesting negative effects on bloodbrain-barrier integrity (121).Further, in cultured primary cortical neurons, acetaldehyde impaired mitochondrial respiration via NOX -mediated activation (122), and in brain mitochondria in vitro , acrolein inhibited mitochondrial respiration via complex I (123)
