AADC Activity Can Be Assessed with High Resolution FMT-PET, Study Shows

Changes in the activity of the enzyme aromatic l-amino acid decarboxylase (AADC) can be assessed through a high-resolution imaging technology called FMT-PET, a new study has confirmed. The study also showed that measuring changes in AADC activity in the brain by FMT-PET — an abbreviation for 6-fluoro-meta-tyrosine positron emission tomography —…

Study Identifies New Mechanisms of AADC Deficiency Mutations

Mutations discovered in the past five years that cause aromatic amino acid decarboxylase (AADC) deficiency affect the functioning of the AADC protein in previously unappreciated ways, namely promoting aggregation and preventing interactions among AADC protein pairs, a molecular study demonstrates. The new mechanisms identified in the study light the…
