GRINA (Glia Derived Nexin): GRINA is a protein that reflects a key component of the central nervous system, particularly involved in neuroprotection and the regulation of neuronal excitability. It interacts with NMDA (N-methyl-D-aspartate) receptors, which are essential for synaptic plasticity, memory formation, and learning. GRINA’s function is linked to its ability to modulate these receptors, influencing neurodevelopment and neural response mechanisms. Dysregulation of GRINA has been associated with neurological disorders such as Alzheimer's disease, epilepsy, and schizophrenia.
