Researchers from the Georg-Speyer-Haus in Frankfurt am Main, Germany, were able to identify a new approach for the therapy of colorectal cancer (CRC) as part of an interdisciplinary project of the LOEWE Center Frankfurt Cancer Institute (FCI). In preclinical models as well as in studies on human immune cells, they found that urolithin A, a metabolite product of the pomegranate, sustainably improves the function of immune cells in their combat against cancer.
