D-Serine is primarily used in neuroscience research due to its role as a co-agonist of the NMDA receptor, which is crucial for synaptic plasticity and memory formation. It is often employed in studies to understand and modulate glutamate signaling in the brain, particularly in conditions like schizophrenia, where NMDA receptor dysfunction is implicated. Additionally, D-Serine is utilized in experimental models to explore its potential therapeutic effects in neurodegenerative diseases, such as Alzheimer's, and in enhancing cognitive functions. Its application also extends to investigating neuropathic pain mechanisms and developing treatments for related disorders.
