Primary sclerosing cholangitis (PSC) is an immune-mediated disease of the bile ducts with no medical treatment. PSC is referred to as ‘the last black box in hepatology’ because there is so much we don’t yet understand about this complex condition, despite impressive research progress in the last decade. People with PSC urgently need a treatment that works. Donating to PSC Support means you are helping us fund more ground-breaking research projects. The next one could be the breakthrough that people with PSC have been waiting for. #LetsBeatPSC
