India, Feb. 18 -- Scientists at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine) have developed a ground-breaking technique to deliver therapeutic molecules directly to the brain, bypassing the blood-brain barrier.

This novel approach utilises a naturally occurring nasal bacterium, Lactobacillus plantarum (Lp), which was genetically engineered to produce therapeutic compounds and release them through a specific nose-to-brain pathway.

The blood-brain barrier (BBB) plays a crucial role in protecting the brain from harmful substances but also poses significant challenges to delivering medications for neurological conditions. Existing drug delivery methods often struggle with limited efficiency and requir...
