摘要:It has been discovered that the stimulation of β-adrenergic receptors, which activate cAMP formation, give rise to increased APP and GFAP synthesis in astrocytes. Hence, the in vitro or in vivo exposure of neuronal cells to certain compositions comprising β-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 β-adrenergic receptor antagonists, such as propranolol. The in vitro or in vivo treatment of these cells with 8Br-cAMP, prostaglandin E 2 (PG E 2 ), 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 β-adrenergic receptors. It has further been found that the increase in APP synthesis caused by 8Br-cAMP, PG E 2 , forskolin, or nicotine ditartrate is inhibited by immunosuppressants 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.

摘要:A method for producing a polysaccharide ester microsphere may include forming a polysaccharide ester product from a polysaccharide synthesis, wherein the polysaccharide ester product comprises a polysaccharide ester and a solvent; diluting the polysaccharide ester product, thereby yielding a polysaccharide ester dope; and forming a plurality of polysaccharide ester microspheres from the polysaccharide ester dope. Suitable polysaccharides may include, but are not limited to, starch, cellulose, hemicellulose, algenates, chitosan, and any combination thereof. Esters thereof may be organic esters (e.g., acetate and the like), inorganic esters (e.g., sulfonates and the like), or combinations thereof. Further, the solids conent of the polysaccharide ester dope, in some instances, may be greater than about 16 wt %.
