Show moreSolute carrier transporters (SLCs) limit receptor activation via uptake of extracellular ligands. Novel concepts are emerging that describe the modulation of intracellular and plasma membrane receptors by ligand influx and efflux via SLCs, respectively. Here, we evaluate recent insights and provide an outlook for developing potential therapeutic strategies. Show less
