Diabetes patients have reduced basal cognitive abilities like learning, memory, and perceptual quickness, as well as a 65 percent higher risk of acquiring AD. AD and diabetes share a number of risk factors, including elevated cholesterol, Aβ deposition, degeneration, inflammation, oxidative stress, cardiovascular diseases, dysmetabolism syndrome, τ-protein phosphorylation, glycogen synthesis kinase 3, apoptosis and apolipoprotein E4. This study explores the potential inhibitory effects of imatinib at doses of 1 and 5 mg/kg, with a particular emphasis on the role of c-Abl in amyloidogenesis, a common mechanism that underlies T2DM and AD. Induction of T2DM induced AD by HFD-STZ-Aβ model. Assessment of behavioural parameters like polydipsia, polyphagia, morris water maze & passive avoidance test; biochemical estimation of glucose, insulin, oxidative stress (SOD, GSH, Cat, TBARS), neuroinflammation (IL-1β, IL-6, TNF-α, NF-κβ), Aβ levels, c-Abl through ELISA technique. Imatinib (1 & 5 mg/kg) results in a reduction in food and water intake, as well as a reduction in memory impairment in the Morris water maze and passive avoidance test. Further, it normalises glucose, insulin, and anti-oxidant elements (SOD, GSH, Cat) levels, while decreasing TBARS levels. Additionally, ELISA data demonstrated a reduction in neuroinflammation (downregulation of IL-1β, IL-6, TNF-α, and NF-κβ), Aβ accumulation, and c-Abl levels by imatinib (1 & 5 mg/kg). Consequently, c-Abl can play a crucial role in the mediation of amyloidogenesis induced by T2DM, thereby establishing a connection between T2DM and AD. Therefore, Imatinib has the potential to treat and prevent the progression of T2DM to AD.
糖尿病患者的基础认知能力如学习、记忆和感知速度会降低,患阿尔茨海默病(AD)的风险也会高出65%。AD和糖尿病有许多共同的风险因素,包括胆固醇升高、β淀粉样蛋白(Aβ)沉积、神经退行性变、炎症、氧化应激、心血管疾病、代谢综合征、τ蛋白磷酸化、糖原合成激酶3、细胞凋亡和载脂蛋白E4。本研究探讨了1毫克/千克和5毫克/千克剂量的伊马替尼的潜在抑制作用,特别强调了c-Abl在淀粉样蛋白生成中的作用,这是2型糖尿病(T2DM)和AD的共同潜在机制。通过高脂饮食-链脲佐菌素-Aβ模型诱导T2DM引发AD。评估诸如多饮、多食、莫里斯水迷宫和被动回避试验等行为参数;通过酶联免疫吸附测定(ELISA)技术对葡萄糖、胰岛素、氧化应激(超氧化物歧化酶、谷胱甘肽、过氧化氢酶、硫代巴比妥酸反应物)、神经炎症(白细胞介素-1β、白细胞介素-6、肿瘤坏死因子-α、核因子-κβ)、Aβ水平、c-Abl进行生化测定。伊马替尼(1毫克/千克和5毫克/千克)可减少食物和水的摄入量,并减轻莫里斯水迷宫试验和被动回避试验中的记忆障碍。此外,它可使葡萄糖、胰岛素和抗氧化元素(超氧化物歧化酶、谷胱甘肽、过氧化氢酶)水平恢复正常,同时降低硫代巴比妥酸反应物水平。此外,ELISA数据显示,伊马替尼(1毫克/千克和5毫克/千克)可减轻神经炎症(白细胞介素-1β、白细胞介素-6、肿瘤坏死因子-α和核因子-κβ的下调)、Aβ积累和c-Abl水平。因此,c-Abl在介导T2DM诱导的淀粉样蛋白生成中可能起关键作用,从而在T2DM和AD之间建立联系。所以,伊马替尼有潜力治疗和预防T2DM向AD进展。
