Mise en évidence de transporteurs de la résistance pléiotropique dans la muqueuse olfactive et leur implication dans la réponse aux odorants chez les…

Multidrug resistance (MDR) is a property of various cells associated with the capacity to reject or efflux a wide range of potentially harmful substances out of the cell. Pumps that effect such efflux are membrane proteins and belong to the ATP- binding cassette (ABC) superfamily. Among the members of the ABC family two are conferring MDR, P-glycoprotein (Pgp) and the multidrug resistance-associated protein (MRP1). In this study we investigated the functional activity of MDR transporters in olfactory mucosa of two species, rat and mouse. We used the fluorometric calcein-AM uptake assay on olfactory mucosal slices incubated with specific inhibitors of the MDR-transporters, verapamil and cycl…
