项目摘要
Type 2 diabetes mellitus (T2DM) is a prevalent disease in the elderly for which current treatments are available, but not satisfactory. It is a chronic, age-related degenerative disorder that is a leading cause of morbidity and mortality in the elderly, and has attained epidemic proportion, with some 425 million afflicted with diabetes worldwide. A variety of risk factors have been implicated in the development of T2DM (Gtz et al. Cell Mol Life Sci 66:1321-5, 2009; Jin & Patti, Clin Sci 116:99-111, 2009), including a genetic predisposition, age, oxidative stress, obesity, diet, and physical inactivity. By comparison, several of these same factors appear to be involved in neurodegenerative disorders, such as Alzheimer's disease (AD), the most common dementia (Reddy et al. J Alzheimers Dis 16:763-74, 2009; Luchsinger & Gustafson, J Alzheimers Dis 16:693-704, 2009). Interestingly, a number of well-designed epidemiological studies have established a link between these two diseases, together with others, including Parkinson's disease (PD) and stroke, identifying T2DM as a risk factor for developing various chronic and acute neurodegenerative disorders (Toro et al. J Alzheimers Dis 16:687-91, 2009; Craft, Curr Alzheimer Res 4:147-52, 2007). The pancreas and brain are both highly insulin sensitive tissues. T2DM and AD, together with other neurological conditions (fibromyalgia: Pappolla et al. Pain Physician 24:175-184, 2021), share several clinical and biochemical features. Particularly important amongst these is an impaired insulin signaling, suggesting overlapping pathogenic mechanisms. Hence, an effective treatment strategy in one disease could have potential value in the other.
A recent effective treatment strategy in T2DM is the use of incretin-based therapies based on the insulinotropic actions of the endogenous peptide, glucagon-like peptide-1 (GLP-1), utilizing the long-acting analog exendin-4 (Ex-4) (Drucker, Diabetes 62:3316-23, 2013). The acute actions of GLP-1 and receptor (R) agonists on beta-cells include stimulation of glucose-dependent insulin release, augmentation of insulin biosynthesis and stimulation of insulin gene transcription. Chronic actions include stimulation of beta-cell proliferation, induction of islet neogenesis and inhibition of beta-cell apoptosis that, together, promote expansion of beta-cell mass and the normalization of insulin signaling (Drucker, Diabetes 64:317-26, 2015). Ex-4 has been reported to readily enter the brain (Kastin et al. Int J Obes Relat Metab Disord 27:313-8, 2003), where the GLP-1R is expressed widely (Perry & Greig, Trends Pharmacol Sci 24:377-83, 2003) and its activation results in multiple biological responses. GLP-1R stimulation in brain is classically allied to regulation of appetite and satiety (Drucker ibid, 2015). More recently, however, it has been associated with neurotrophic (Perry et al., J Pharmacol Exp Ther 300:958-66, 2002) and neuroprotective actions in both cellular and in vivo models of acute and chronic neurodegenerative conditions (Perry et al. J Pharmacol Exp There 302:881-8., 2002; Perry et al. J Neurosci Res 72:603-12, 2003), including stroke, AD, PD and Huntingtons disease (HD) (Li et al. PNAS 106:1285-90, 2009; Li et al. J Alz Dis 19:1205-19, 2010; Harkavyi et al. J Neuroinflamm 21:519, 2008; Kim et al. Cell Transplant 26:1560-71, 2017; Glotfelty et al. ACS Pharmacol Transl Sci 2:66-91, 2019).
Our target for drug design is the GLP-1R. GLP-1 is secreted from the gut in response to food and is a potent secretagogue that binds to the GLP-1R on pancreatic beta-cells to induce glucose-dependent insulin secretion, thereby regulating plasma glucose levels. We are evaluating long-acting GLP-1 analogues (collaborators: Drs. Hoffer, DiMarchi, Pick, Mattson, Wang, Kim, Egan). This research aided in the development of the peptide exendin-4 (Ex-4) into clinicall studies in type 2 diabetes. Novel chimeric peptidesthat combine the best features of GLP-1 and Ex-4 have also been designed and assessed in a variety preclinical models (Wang et al. J Clin Invest 99:2883-9, 1997, DeOre et al. J Gerontol A Biol Sci Med Sci 52:B245-9, 1997; Greig et al. Diabetologia 42:45-50, 1999; Szayna et al. Endocrinol 141:1936-41, 2000; Doyle et al. Endocrinol 142:4462-8, 2001; Doyle et al. Regul Pept 114:153-8, 2003; Doyle et al. Endocrine 27:1-9, 2005). We are characterizing the role of GLP-1R stimulation in the nervous system, as it is found present in brain and peripheral nerve. Our collaborative studies were the first to define that GLP-1 analogs possess neurotrophic properties and protect neuronal cells from a wide variety of lethal insults. Neuroprotection and anti-inflammation in cell culture translated to in vivo studies in classical rodent neurodegeneration models, which include AD, stroke, PD, HD, ALS, traumatic brain injury and peripheral neuropathy (as reviewed in Greig et al. Alzheimers Dement 10(1S):S62-75, 2014; Kim et al. Cell Transplant 26:1560-71, 2017; Glotfelty et al. ACS Pharmacol Transl Sci 2:66-91, 2019; Glotfelty et al., Expert Opin Investig Drugs 29:595-602, 2020). Current studies are focused on selecting agents for clinical assessment and defining mechanisms underpinning the neurotrophic/neuroprotective actions (Li et al. J Neurochem 113:621-31, 2010; Li et al. J Neurochem 135:1203-17, 2015; Chen et al. Sci Rep 8:10722, 2018; Bader et al. Neurobiol Dis 124: 439-53, 2019). Additional research is focused on optimizing the translation of Ex-4 for the treatment of neurodegenerative disorders, and defining which specific disorders are most likely to have a clinical response. Specifically, the long-acting GLP-1 receptor agonist exendin-4 has been evaluated in human MCI/early AD (Collaborators: Drs. Kapogiannis, Egan, Mattson: Curr Alzheimer Res 16:741-52, 2019) and a trial in PD has been completed (Lancet 390:1664-75, 2017; JAMA Neurol 76:420-9, 2019; Collaborators: Drs. Foltynie, Athauda). Other clinical trials in different disorders are on going involving a sustained-release formulation of Ex-4 (PT320, Peptron, S. Korea) (Collaborators: Drs. Choi, Jung & Peptron colleagues; Hoffer; Kapogiannis), as well as in idiopathic intracranial hypertension (Dr. Alex Sinclair).
An alternate approach is to augment the levels of endogenous incretins available within the body by inhibiting their metabolism and to, thereby, elevate their levels. In this regard, GLP-1 and the incretin, glucose-dependent insulinotropic polypeptide (GIP) are released following food ingestion and bind to their respective receptors on pancreatic beta cells to induce insulin secretion. Receptors for these endogenous peptides are found throughout the body, including the brain - which both GLP-1 and GIP can readily enter. The presence of the metabolizing serine protease enzyme, dipeptidyl peptidase-4 (DPP-4), results in the rapid clearance of both incretins. Current studies are assessing the utility of selective and well tolerated DPP-4 inhibitors in cellular and preclinical animal studies to elevate available GLP-1 and GIP levels in plasma and brain to a level at which they may provide neurotrophic/protective actions for the treatment of neurodegenerative disorders. Still other approaches being evaluated involve augmenting GIP-R and GLP-1R stimulation separately and together by the use of dual incretin mimetic peptides, and tri-incretin mimetics to the glucagon receptor too. Ongoing studies are in preclinical stages to both evaluate new drug development and drug repurposing towards neurological disorders currently lacking effective pharmacological treatment where this incretin strategy could prove highly beneficial (Collaborators: Drs. Foltynie, Athuada, Wang, Hoffer, Tones, Zaleska, Mattison, Kim, DiMarchi, Peptron colleagues). Current preclinical studies also are evaluating incretin mimetics in COVID-19 studies
2型糖尿病(T2DM)是老年人的一种流行疾病,目前的治疗方法是可行的,但并不令人满意。糖尿病是一种与年龄有关的慢性退行性疾病,是老年人发病和死亡的主要原因,已成为流行病,全世界约有4.25亿人患有糖尿病。多种危险因素与T2DM的发展有关(Gtz等)。生物科学进展(英文版);2009;Jin & Patti,临床科学116:99-111,2009),包括遗传易感性、年龄、氧化应激、肥胖、饮食和缺乏运动。相比之下,这些相同的因素中有几个似乎与神经退行性疾病有关,如阿尔茨海默病(AD),最常见的痴呆症(Reddy等)。中华老年痴呆症杂志(英文版);2009;《老年痴呆症杂志》(英文版),2009年第6期。有趣的是,许多精心设计的流行病学研究已经建立了这两种疾病之间的联系,以及其他疾病,包括帕金森病(PD)和中风,确定T2DM是发展各种慢性和急性神经退行性疾病的危险因素(Toro等)。中华老年痴呆症杂志(英文版);2009;《老年痴呆症杂志》(第4期),2007年。胰腺和大脑都是胰岛素高度敏感的组织。2型糖尿病和AD,连同其他神经系统疾病(纤维肌痛:Pappolla等。疼痛医师24:175-184,2021),共享几个临床和生化特征。其中特别重要的是胰岛素信号受损,提示重叠的致病机制。因此,一种疾病的有效治疗策略可能对另一种疾病具有潜在价值。
