SLC6A3 and Parkinson disease: 11C‐CFT, a DAT PET imaging agent with high affinity and selectivity for dopamine transporterand resistance to metabolic degradation, is commonly used for brain imaging to diagnose neurodegenerative diseases such as Parkinson's disease (PD), reflecting dopaminergic neuron damage.[31, 32, 33] Dopamine receptors are also widely expressed in cochlear SGNs,[34, 35] prompting us to test 11C‐CFT in the two aforementioned animal models.
