Cancer researchers ‘switch on’ Natural Killer cells to fight cancer Posted on June 8, 2016February 25, 2018 by Carly du Toit Walter and Eliza Hall Institute (WEHI) researchers, led by Dr Sandra Nicholson and Dr Nicholas Huntington, together with colleagues from the Queensland Institute of Medical Research (QIMR), are investigating ways to ‘switch on’ our Natural Killer (NK) cells to fight cancer. The researchers identified a protein ‘brake’ within Natural Killer cells that controls their ability to destroy their target tumour cells. “Natural Killer cells exist to detect and then destroy any deviant cells in our bodies before those cells go on to develop into tumours or before infection spreads,” Dr Nicholson said. “Natural Killer cells are a key part of our immune system they work by locating other cells posing a danger to health either because they are infected or because they are becoming a cancer cell,” she continued. Our bodies are constantly and successfully fighting off the development of cells that lead to tumours – but when there is disruption to this process cancer is free to develop. In their paper published in Nature Immunology, they showed that when the brake was removed in an experimental model, the NK cells were better able to protect the body against metastatic melanoma. Natural Killer cells rely on a growth factor called Interleukin 15 (IL15) to activate. Dr Nicholson and Dr Huntington’s research has shown that an inhibitor protein made inside the Natural Killer cells limits the ability of the NK cell to respond to IL15 and therefore kill cancer cells. By identifying for the first time how this protein inhibits NK cell responses, they now hope that a drug can be developed that will improve the response of NK cells to this growth factor and help patients fight cancer with their own immune system. “This is about learning how to activate the NK cells of the individual patient and boost their immune system to tackle the disease,” Dr Huntington said. “We are hopeful our research will lead to new immunotherapies that supercharge the body’s Natural Killer cells and maintain it in a highly active state to more efficiently and specifically fight cancer.” The Australian Cancer Research Foundation has supported WEHI by providing three grants, totalling AUD 5.5million towards cutting edge cancer research equipment and technology.

A man honours his hero, best friend and father Posted on May 19, 2015March 14, 2018 by Carly du Toit “I have chosen to become a Partner in the Cure due to the recent passing of my father, Stan Phillips, at age 76. My father was a major influence on me and truly was a great man. He lived his life to the fullest and touched the hearts of many. He lived a long life, but for me his passing still came too soon, I was hoping he would be around longer to see his two grandchildren grow up. He was very fit and I think he would have had years left if it wasn’t for cancer. It was a shock when he had to be rushed to hospital and we discovered he had bowel cancer. He fought a hard battle for three years right up until he passed, and through it all he was positive, smiling and enjoying life. He was a real family man who put us first and was more concerned with my family than his own struggle. He worked hard to give us every opportunity in life and rarely treated himself. He was my mentor, training partner and best friend. The way he lived his life and fought cancer is why he is my role model; I will be happy if I can live up to just half of his standards and I hope I can pass this attitude to life onto my children. It’s amazing what a perfect father he was especially when he lost his own in the 2nd World War at the age of four. His determination in life led him to be successful in several different careers, starting out as a carpenter, then serving in the Elite Parachute Regiment, and finally becoming a construction site manager. He was also wonderful husband to my mother Margret. Today would have been their 50th Wedding Anniversary. Karate was one of his favourite hobbies. He trained for eight years earning his black belt in 1983 and only stopping a few months prior to his passing when he became too ill. The club he belonged to now awards a trophy in his name. He requested that people make donations to cancer research in lieu of bringing flowers to his funeral. He believed, as I do, that if we can contribute to the advancement for a cure it will one day save my children or grandchildren from this terrible disease,” Nathan Phillips. Share your story
