Abstract: Described herein are methods for inhibiting generation of one or more non-classical variant(s) of amyloid precursor protein (APP) gene. Provided herein are methods for diagnosing an individual having or suspected of having Alzheimer's-disease following identification of an expression profile or an activity profile of the one or more non-classical variant(s) and treating the individual using a reverse transcriptase inhibitor or salt thereof.

Abstract: The invention relates to methods of modulating neurite outgrowth, in culture or in a subject. The methods generally utilize cell-signaling phospholipids which interact and bind to the G protein-coupled cellular receptors (GPCRs). Such phospholipids include lysophospholipids, as well as synthetic lysophospholipid receptor agonists and antagonists that may be chemically distinct from lysophospholipids. The methods include contacting astrocytes with an effective amount of a lysophospholipid agent, and contacting neurons with the astrocytes. The methods also include treating neurons by contacting the neurons with astrocytes pretreated with a lysophospholipid agent. The methods further include contacting the neurons with an effective amount of an astrocyte-derived soluble factor (ADSF).
