Improving Brain Resilience: Rab Proteins and Future Treatments
How Rab Proteins Orchestrate Synaptic Potentiation Memory formation hinges on synaptic potentiation—the strengthening of connections between neurons. This growth is driven by a tightly coordinated delivery system within neurons that supplies the building blocks essential for remodeling synapses. A large family of cellular switches, known as Rab proteins, governs the flow of these supplies, directing…
