Described herein are compositions and techniques related to generation and therapeutic application of artificial synapses. Artificial synapses are engineered extracellular vesicles, including exosomes, which incorporate sticky binders on their surface to anchor signaling domains against biological targets, such as receptors. These engineered additives can be organized in genetic vector constructs, expressed in mammalian cells, wherein the sticky binders attach to extracellular vesicles such as exosomes, thereby presenting their joined signaling domains which are rapidly taken up by recipient cells. Artificial synapses adopt the hallmark biophysical and biochemical features of extracellular vesicles, allowing for rapid deployment and scale-up. Importantly, this strategy can allow for kinetically favorable signal generation and signal propagation. This includes, for example, increasing density of agonist presentation to support receptor clustering—an onerous barrier for traditional receptor targeting strategies.

The present invention relates to a novel use for HDL-ApoM-S1P (a high density lipoprotein in which apolipoprotein M is impregnated with sphingosine-1-phosphate), and more particularly, to using HDL-ApoM-S1P to prevent, improve, or treat degenerative brain disorders (in particular, Alzheimer's disease), cognitive disorders, learning disabilities, and memory disorders, and using HDL-ApoM-S1P to improve cognitive ability, learning ability, and memory.

The HDL-ApoM-S1P according to the present invention not only alleviates neuroinflammation but also significantly exhibits improvement effects of cognitive disorder, learning disability, and memory disorder with respect to individuals suffering from degenerative brain disorders (in particular, Alzheimer's disease), and exhibits an effect of greatly reducing amyloid beta and tau deposition. Moreover, increased HDL-ApoM-S1P in the body also has an excellent effect of improving the cognitive, learning, and memory abilities of non-disabled individuals.
