Endogenous retroviruses expressed in human tumours cannot be used as targets for anti-tumour vaccines

Abstract

Many tumour cells express on their surface proteins of endogenous retroviruses (ERVs) and there are suggestions to use these retroviral antigens as target for anti-tumour vaccines. However, until now there is no convincing data showing that this strategy works, in contrast, there are considerations suggesting that this strategy may be harmful if applied.
