Abstract

Background: Chronic inflammation has critical role in Type 2 Diabetes (T2D), in which IL-1β contributes in insulin resistance and beta cell dysfunction. The activation of NLRP3 and AIM2 by endogens ligands, such as mtDNA can lead to the release of active form of IL-1β . Objective: To evaluate AIM2 expression and activation as well as circulating mtDNA levels in T2D patients. Methods: AIM2 expression was analyzed by flow cytometry, it’ s activity was assessed by measuring in vitro release of IL-1β induced by Poly (dA: dT), and mtDNA copy number was determined by quantitative real-time polymerase chain reaction. Results: Increased percent of AIM2+ cells were detected in monocytes from patients with T2D. Moreover, increased levels of IL-1β in monocytes cultures from T2D patients compared to healthy controls were observed. Also, association between AIM2+ cells and hyperglycemia (r=0. 4385, P=0. 0095) and triglycerides levels (r=0. 5112, P=0. 002) and waist-hip ratio (r=0. 4710, P=0. 0049) were detected. Likewise, the mtDNA copy number was augmented in T2D patients compared to control group. The mtDNA copies number was associated with body mass index (r=0. 4231, P=0. 0008) and TNF-α levels (r=0. 5231, P=0. 0005). In addition, increased levels of IL-12p70, TNF-a, IL-10, IL-6, IL-8 and IL-1β were detected in a serum from T2D patients. Conclusion: These results suggest the involvement of AIM2 and mtDNA in the inflammatory process seen in T2D.
