Type 2 diabetes mellitus (T2D) is becoming increasingly prevalent worldwide and complications of T2D cause significant systemic and dental morbidity in the susceptible individual. Although T2D has been linked as a significant risk factor for chronic periodontitis (CP), molecular mechanisms explaining the pathogenesis and inflammatory impact of CP in T2D are lacking. iPLA2 is the calcium-independent form of phospholipase A2. In previous studies, we demonstrated that iPLA2 enzyme activity is altered in T2D. The purpose of this study was to elucidate the level of the iPLA2 abnormality in T2D by measuring messenger RNA levels in T2D-associated CP. A total of 53 healthy and T2D subjects with CP were recruited for this study. The clinical periodontal exam included probing pocket depth, clinical attachment levels and bleeding on probing. Peripheral venous blood was collected and neutrophils were isolated. Real time polymerase chain reaction was used to quantify iPLA2 mRNA in neutrophils from healthy controls and people with diabetes. Results revealed that the prevalence of moderate to severe CP was increased in people with T2D. The iPLA, mRNA levels in diabetics with different severity of CP were not significantly different compared to healthy controls; 1.07 vs 0.97 (mild CP), 1.07 vs 0.85 (moderate CP) and 1.07 vs 1.05 (severe CP). Collectively, the data suggest that levels of iPLA2 mRNA in T2D are not different than in health and are not directly influenced by periodontal disease status. The impact of inflammation on iPLA2 regulation is at the level of activation of the enzyme rather than expression at the mRNA level.
