Membrane lipid poly-unsaturation selectively affects dopamine D2 receptor internalization

S. Sposini, R. Baccouch, M. Lescuyer, A. A. Mali, V. De Smedt-Peyrusse, J. Heuninck, A. Gorse, T. Durroux, P. Trifilieff, D. Perrais, I. Alves

This study shows that membrane poly-unsaturated fatty acids (PUFAs) impair dopamine D2 receptor (D2R) endocytosis without affecting other GPCRs or clathrin-mediated endocytosis.
