Oncolytic viral immune therapy, adenocarcinomas, breast cancer, bladder cancer, liver cancer, nectin-4 tumour marker
Our laboratory recently discovered a “receptor” for measles virus which turned out to be a tumor marker called PVRL4/Nectin-4. This marker is found on many breast, bladder, and liver tumours. Receptors are cellular molecules to which the virus attaches, in order to initiate infection. This explains why measles virus can target a wide variety of cancers. We are using a mouse breast cancer model to investigate whether measles and an engineered hybrid virus can kill tumors.
