    • It has been discovered that the stimulation of beta -adrenergic receptors, which activate cAMP formation, gives rise to increased APP and GFAP synthesis in astrocytes. Hence, the in vitro or in vivo exposure of neuronal cells to certain compositions comprising beta -adrenergic receptor ligands or agonists, including, e.g., norepinephrine, isoproterenol and the like, increases APP mRNA transcription and consequent APP overproduction. These increases are blocked by beta -adrenergic receptor antagonists, such as propranolol. The in vitro or in vivo treatment of these cells with 8Br-cAMP, prostaglandin E2 (PG E2), forskolin, and nicotine ditartrate also increased APP synthesis, including an increase in mRNA and holoprotein levels, as well as an increase in the expression of glial fibrillary acidic protein (GFAP). Compositions and methods are disclosed of regulating APP overexpression and mediating reactive astrogliosis through cAMP signaling or the activation of beta -adrenergic receptors. It has further been found that the increase in APP synthesis caused by 8Br-cAMP, PG E2, or forskolin is inhibited by immunosuppressants, immunophilin ligands, or anti-inflammatory agents, such as cyclosporin A, and FK-506 (tacrolimus), as well as ion-channel modulators, including ion chelating agents such as EGTA, or calcium/calmodulin kinase inhibitors, such as KN93. The present invention has broad implications in the alleviation, treatment, or prevention of neurological disorders and neurodegenerative diseases, including Alzheimer's Disease.
    • 已经发现刺激cAMP形成的β-肾上腺素能受体的刺激引起星形胶质细胞中APP和GFAP合成的增加。 因此,将神经元细胞体外或体内暴露于包含β-肾上腺素受体配体或激动剂(包括例如去甲肾上腺素,异丙肾上腺素等)的某些组合物 APP mRNA转录和随后的APP过量产生。 这些增加被β-肾上腺素能受体拮抗剂如普萘洛尔所阻断。 这些细胞用8Br-cAMP,前列腺素E2(PG E2),毛喉素和酒石酸二酒石酸盐进行的体外或体内治疗也增加了APP合成,包括增加 mRNA和全蛋白水平,以及胶质纤维酸性蛋白(GFAP)表达的增加。 公开了调节APP过表达和通过cAMP信号传导或β-肾上腺素能受体的激活介导反应性星形胶质化的组合物和方法。 进一步发现,由8Br-cAMP,PG E2或毛喉素引起的APP合成的增加被免疫抑制剂,亲免素配体或抗炎剂如环孢菌素A和FK-506(他克莫司)所抑制,如 以及离子通道调节剂,包括离子螯合剂如EGTA,或钙/钙调蛋白激酶抑制剂如KN93。 本发明在减轻,治疗或预防包括阿尔茨海默氏病的神经病症和神经退行性疾病方面具有广泛的意义。
