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 invention provides a process of incorporation of omega-3 fatty acids such as EPA/DHA into polar lipid molecules present in lecithin, which consists of: (a) an enzymatic exchange reaction between the fatty acids present in the polar lipids of lecithin and the omega-3 fatty acids present in concentrated fish oil, to obtain an oil with a high content of polar lipids and omega-3 fatty acids and (b) a stage of concentration of the polar lipid content of the oil obtained in stage a, by supercritical fractionation or molecular distillation. The composition of the invention promotes at least a 25% peak incremental concentration in plasma of the EPA/DHA when compared to a krill oil derived composition.
