Targeting the bile acid receptor TGR5 with Gentiopicroside to activate Nrf2 antioxidant signaling and mitigate Parkinson's disease in an MPTP mouse model.

Summary: Parkinson's disease causes shaking and stiffness because brain cells get damaged by harmful stress. Scientists tested a natural plant extract called GPS in mice with Parkinson's. They found that GPS acts like a protective shield. It flips a special switch in the brain called TGR5, which turns on the body's own cleaning system to protect brain cells from damage. The mice given GPS kept more of their healthy brain cells and moved much better! This plant extract shows great promise as a future treatment to slow down Parkinson's disease.
