Updated:

Recent clinical studies have demonstrated that specific probiotic strains can influence cognitive function and neurological health through gut-brain axis mechanisms. Measurements of neurotransmitter levels, inflammatory markers, and cognitive performance metrics show significant changes after targeted probiotic interventions. For example, PS128 administration has been shown to increase neurotransmitter production in AADC deficiency patients, while specific Lactobacillus strains demonstrate measurable effects on memory and learning parameters.

The core challenge lies in identifying and validating specific bacterial strains that can survive gastrointestinal transit, colonize effectively, and produce neurologically active compounds in sufficient quantities to cross the blood-brain barrier.

This page brings together solutions from recent research—including engineered probiotics for neurotransmitter production, nano-protected bacterial delivery systems, strain combinations for enhanced cognitive function, and microbiome modulation approaches for neurodegenerative conditions. These and other approaches focus on translating gut-brain axis insights into practical therapeutic interventions for neurological and cognitive disorders.

1. Liposome-Encapsulated Probiotic Bacteria with Gamma-Aminobutyric Acid Production Capability

Tangyi Holdings(Shenzhen) Limited, 2023

A nano-armored single cell product for treating Parkinson's disease that encapsulates probiotic bacteria producing gamma-aminobutyric acid (GABA) inside liposomes. The liposome coating protects the bacteria from stomach acid and enzymes during oral ingestion. Once in the intestines, the liposomes break down and release the bacteria to produce GABA that can be absorbed into the bloodstream and cross the blood-brain barrier to potentially alleviate Parkinson's symptoms.
