Abstract:Research on the association between platelet monoamine oxidase (MAO) activity and personality traits, such as sensation seeking and impulsiveness, is reviewed with an emphasis on early history and current situation. The effects of MAO-inhibiting compounds in cigarette smoke for the interpretation of this association are discussed and recent results confirming a true association between platelet MAO activity and personality and vulnerability, for e.g. type 2 alcoholism are presented. From a clinical point of view, the link between platelet MAO activity, which is highly genetically regulated and is stable in the individual, and personality traits, has had its greatest impact on the understanding of the nature of constitutional factors making individuals vulnerable, for e.g. substance abuse and other forms of sociopathic behaviour. The molecular mechanisms underlying the association between platelet MAO and behaviour are discussed and evidence that common transcriptional factors, e.g. within the AP-2 family, regulating both the expression of platelet MAO and components of the central monoaminergic systems, such as synthesising enzymes, receptors and transporters, are presented. A hypothesis is put forward, that such common transcription factors may not directly regulate platelet MAO expression, but rather mitochondrial density, or outer mitochondrial membrane surface.
