Overexpression of Mdr65G1190D.Scer\UAS.T:Avic\GFP in the humoral interface (at the blood-brain barrier) under the control of Scer\GAL4SPG significantly decreases brain-specific Rhodamine B content, implicating a role for Mdr65 in blood-brain barrier transport.
Expression of Mdr65G1190D.Scer\UAS.T:Avic\GFP at the humoral interface under the control of Scer\GAL4SPG is sufficient to restore efflux transport of small-molecule fluors, indicating that a role of Mdr65 in CNS protection is localized to the SPG.
