This study aimed to evaluate the effect of Tithonia diversifolia extract (TDE) on leptin, adiponectin, and insulin receptor (IR) concentrations in diabetic rats. Twenty-four Wistar rats were divided into a control and treatment groups (n=6 per group). The control group received normal saline, and the treatment groups received 0.25% sodium carboxy-methyl cellulose, TDE at 100 mg/kg body weight (bw), and catechin at 10 mg/kg bw for 7 days. On day 8, the rats were sacrificed, blood samples were obtained, and leptin, adiponectin, and insulin concentrations were measured using avidin-horseradish peroxidase sandwich-enzyme-linked immunosorbent assay. A calorimetric method was used to measure blood glucose (BG) and total serum cholesterol concentrations. The pancreas and kidneys were collected for the measurement of renal IR and macrophage cluster of differentiation (CD)14 levels using immunohistochemical staining. Acute type 2 diabetes mellitus (T2DM) with elevated BG and total serum cholesterol concentrations was observed in the treatment groups administered streptozotocin. The administration of TDE at 100 mg/kg bw significantly decreased leptin and increased adiponectin concentrations (P≤0.05). Furthermore, TDE treatment significantly increased renal IR and decreased macrophage CD14 levels (P<0.05). Therefore, TDE decreased leptin and BG concentrations by increasing IR levels. TDE also suppressed the necrosis of pancreatic tissues by inhibiting macrophage CD14 expression in diabetic rats. However, further research is necessary to determine the effect of TDE on interleukin and IR levels in the related tissues of patients with T2DM.
