P-gp could play role in the development of AD by depleting Ach levels.
Rivastigmine lowers Aβ brain load, at least in part, by upregulating P-gp and LRP1 at the BBB.
P-gp deletion attenuates rivastigmine effect on Aβ and its related pathology.
Rivastigmine's neuroprotective effect is P-gp expression dependent (APP/mdr1+/+ > APP/mdr1+/−>APP/mdr1−/−).
