London, Apr 27 : Scientists from The Campbell Family Institute for Breast Cancer Research have identified a novel way to boost immune response to cancer.

During the study, the research team led by Dr. Pamela Ohashi, co-director, CFIBCR combined interleukin-7 (IL-7), a key component of the immune system, with a viral vaccine to improve the ability of the cells of the immune system to attack tumours.

They found that the combination improved immunity to tumours.

"We are extremely excited because our research has revealed the unexpected ways IL-7 works to break down barriers that naturally block the immune response to tumours," Nature quoted Dr. Ohashi as saying.

"This is important because current vaccine approaches for immune therapy induce a response in just 1pct to 3pct of patients," she added.

"The promise of using the body''s own defenses to fight cancer is enormous," said Dr. Tak Mak, co-author and CFIBCR director.

"The day is coming when immunotherapy may help spare cancer patients the toxic side effects of traditional therapies and greatly improve their quality of life while treating the disease," Mak added.

The findings are published in Nature Medicine. (ANI)
