Blood-brain barrier (BBB) models are essential for studying drug transport, neurovascular interactions, and disease mechanisms. These models replicate the selective permeability of the BBB, allowing researchers to investigate how therapeutic agents cross into the brain. Scientists use various approaches, including in vitro co-culture systems, microfluidic platforms, and organoid-based models, to enhance the physiological relevance of BBB studies. Advancements in BBB modeling contribute to drug discovery, neurodegenerative disease research, and precision medicine applications.
