Lp-PLA2 Selective Inhibitor (Darapladib) Effect In Lowering The Expression Level Of IL-1B And IL-6 In The Renal At Type 2 Diabetes Mellitus

Abstract

Purpose The aim of this study is to prove that type 2 diabetes mellitus can induce increasing inflammation marker in renal and that the provision of darapladib as Lp-LA2 Inhibitor agents can inhibit inflammation that were measured from the expression of IL-1B and IL-6- type cytokine in renal. This study also discusses the correlation between IL-1B and IL-6- type cytokine expression in renal.

Methods Thirty Sprague-Dawley (SD) rats were divided into three main groups; those are negative control group (NC), Type 2 Diabetes Mellitus group (T2DM) given high fat diet (HFD) with streptozotocin intraperitoneal injection (35mg/kg BW) and diabetes mellitus + darapladib group (DM + DP). Each group was treated within two serial treatment time: 8 weeks and 16 weeks. Expressions of IL-1B and IL-6- type cytokine in renal were the markers that we measured by immunofluorosense method.

Results The administration of darapladib can significantly decrease the expression of IL-1B- type cytokine (p ANOVA = 0.029, p < 0.005) measured in rats’ renal both at weeks 8 and 16 in the T2DM group. The Expression of IL-6- type cytokine also showed a significant difference after treated with darapladib both at weeks 8 and 16 in T2DM group with p-value of ANOVA = 0.033, p < 0.005. The Pearson correlation showed a strong correlation (linear regression value was r2 = 0.743).

Conclusion Our results show that atherosclerosis caused by inflammation in renal T2DM SD rats could be inhibited by the administration of darapladib.
