Abstract


Purpose: MPTP-induced dopaminergic degeneration is an experimental model commonly used to explore Parkinson’s disease. Cerebral drug transport by ABC transporters in MPTP models has never been reported.
Methods: We have investigated the transport of bromocriptine through the blood-brain barrier (BBB) in a MPTP model to understand the influence of the dopaminergic degeneration on ABCB1 and ABCG2.
Results: We have shown that in MPTP treated mice, bromocriptine is widely distributed to brain (2.3-fold versus control, p
