Research Interests
My research is focused on the enhancement of the oncolytic capacity of Newcastle disease virus (NDV), considered nowadays one of the most promising viral vectors for cancer treatment. Using reverse genetics technology, we are able to generate new recombinant NDVs capable of inducing better and more specific therapeutic responses in different in vivo murine tumor models. The development of new armed NDVs provides us with an extraordinary tool to target programmed cell death, create innate and adaptive anti-tumor responses and design more efficient cancer virotherapies. Our latest work has focused on the enhancement of the killing capacity of NDV, arming the virus with the pro-apoptotic human Fas receptor. Our results showed that the manipulation of the death pathways involved in the cellular response to NDV is a rational strategy to improve natural antitumor activity, with extraordinary therapeutic benefits in very aggressive tumor models like melanoma.

The cover images show murine B16-F10 melanoma (Mol Cancer Ther., left) and human HeLa cells (Virus Res., right) infected by the recombinant rNDV-B1/Fas virus undergoing apoptotic cell death. The human Fas receptor (red) is expressed on the surface of infected cells (green). DNA was counterstained with Hoechst.
