Despite a body of evidence supporting the deleterious health risks associated with tobacco use, a vast number of people continue to suffer from smoking-related ailments. In order to fully understand the role of smoking in the onset and advancement of many of its associated disease states, we have recently initiated a research program studying the role of long-lived nicotine metabolites in disease. Specifically, we have studied the role of nornicotine, a metabolite we have shown capable of participating in both the catalysis of the aldol reaction and the aberrant covalent glycation of proteins. This lecture will summarize our recent findings in this area, including the effects of this phenomenon in scenarios such as the aggregation of the amyloid ß-protein.
