Boosting the immune system to treat brain cancer

Researchers at the University of Calgary’s Hotchkiss Brain Institute (HBI) have made a discovery that could lead to better treatment for patients suffering from brain cancer.

Despite current treatment strategies, the median survival for patients with the most aggressive brain cancer – called glioblastoma, is 15 months. Less than five per cent of patients survive beyond five years.

HBI member V. Wee Yong, PhD and research associate Susobhan Sarkar, PhD, and their team including researchers from the Department of Clinical Neurosciences and the university’s Southern Alberta Cancer Research Institute, looked at human brain tumour samples and discovered that specialized immune cells in brain tumour patients are compromised. The researchers took this discovery and, in an animal model, identified a drug that is able to re-activate those immune cells and reduce brain tumour growth, thereby increasing the lifespan of mice two to three times. Their discovery was published December 8 in the prestigious journal Nature Neuroscience. Read more here.
