Summary: New research has revealed the diverse assembly and regulation of Type-A GABA receptors (GABAARs), which are crucial for balancing brain activity. Using cryogenic electron microscopy, researchers identified over 324,000 potential receptor structures, shaped by subunit combinations and their relative arrangement.
These variations influence receptor function, drug binding, and the brain’s response to stressors like pregnancy or chronic drug use. The findings pave the way for targeted therapies that enhance receptor-specific functions without inducing tolerance or dependence.
