HALIFAX, NS ―Award-winning Dalhousie University PhD student Simon Gebremeskel is a pioneer in discovering how the immune system can fight cancer.
“The more we know, the more we realize we don’t know. We’re only starting to scratch the surface,” says says Simon Gebremeskel who, as top-prize winner at this year’s Canadian Student Health Research Forum, has earned himself a coveted nomination to attend the Lindau Nobel Laureate Meeting in Germany in 2018.
Simon Gebremeskel is working with Dr. Brent Johnston in Dalhousie Medical School’s Department of Microbiology & Immunology to develop a cancer treatment that kills cancer cells by both activating the immune system and introducing viruses that kill cancer cells. This novel combination strategy — of immunotherapy plus oncolytic viruses — could be available within a few years.
In fact, Simon predicts people with cancer will be treated entirely differently within “the next decade or so,” once the costs of groundbreaking new treatments come down.
The beauty of cancer immunotherapy is that side effects are not as severe as those in surgery, chemotherapy and radiation. And, there is evidence the immune system “remembers,” so it will fight off new attacks by a returning cancer.
It’s a cops and robbers story with scientists racing towards a cure while devious cancer cells try to outwit the immune system.
Cancer as immune deficiency disease
“What’s becoming clear in the field of cancer therapy is the majority of cancer patients should be looked at as patients who have immune deficiency,” says the Kenyan-born scientist, who did his undergraduate degree at Queen’s University. “Normal cells in our body become transformed quite frequently into pre-cancerous or early-stage cancer cells. Evidence suggests the immune system is able to recognize these changed cells and clear them off.”
As Simon Gebremeskel explains, cancer erupts for two reasons: “The immune system fails to recognize the changed cell, which is now cancerous, and the new cancer cell turns off the immune system, essentially enabling it to proliferate without any checks and balances.”
