This fascinating angle on Parkinson’s comes at an exciting time for gut-brain research on neurological problems. The probiotic L Reuteri has just been shown to strengthen the feedback loops between the levels of the dopamine neurotransmitter and the oxytocin hormone, via the vagus nerve, in recent research by Costa-Mattioli (who stumbled upon it looking for treatments for autism, which is known to correlate with gut issues). Perhaps with CRISPR we are open to engineering new probiotics which can more precisely target these gut-related conditions?
