My research focuses on development of new cancer therapies, where viruses are used as a novel anti-cancer drugs.
I did my four-year PhD studies under supervision of Prof. Magnus Essand and my work resulted in the development of what is known as an adenovirus that can specifically kill neuroendocrine cancer cells.
We have published four articles where we describe various ways of controlling and modifying the virus to kill cancer cells, leaving normal cells unharmed. Paper I describes the modification of viral DNA to make it multiply to kill only neuroendocrine cancer cells.
In paper II we describe how we protect normal, non-cancerous, cells from the virus. In papers III and IV we demonstrate how we modified the virus’ surface to improve its ability to infect and spread in tumours.
Our virus has a good efficacy in killing neuroendocrine tumours (NET) in mice. Our hopes are that this treatment will have significant effects for NET patients as well. The only way to find out if our virus can help cancer patients is to perform a clinical trial and to do so we need support from public.
