Fig. 7

Higher abundance of tyrosine decarboxylase can explain increased levodopa administration requirement in Parkinson’s disease patients. A model representing two opposing situations, in which the proximal small intestine is colonized by low (left) or high abundance of tyrosine decarboxylase-encoding bacteria. The latter could result from or lead to increased individual L-DOPA dosage intake
