Preventing drugs from being transported

Pharmacology - Jun 17

Certain membrane proteins specialise in transporting molecules out of cells - a problem for the efficacy of cancer medication and antibiotics. An international research team has investigated the transport mechanism of a bacterial membrane protein using an artificially produced antibody fragment. The transport proteins, called ABC exporters, are present, for instance, in the cell membranes of bacteria and in large quantities in cancer cells and are responsible for transporting small molecules out of the cells.
