03.12.2012 - French researchers have identified how the body’s immune systems triggers therapy resistance to the cancer drugs gemcitabine and 5-fluorouracil.
The researchers, headed by François Ghiringhelli from INSERM in Dijon, found that in mice, the drugs activate a protein complex, termed Nlrp3 inflammasome, in myeloid derived suppressor cells. This activation leads to the release of the immune cell interleukin (IL)-1 beta, which then skews T immune cells to produce protumorigenic IL-17 and results in enhanced growth of tumours in mice (Nature Medicine, doi: 10.1038/nm.2999).
The chemotherapeutics were more efficacious at inhibiting tumour growth in mice lacking Nlrp3 or IL-17, or treated with an IL-1 receptor antagonist. The findings suggest that targeting the inflammasome pathway in conjunction with chemotherapy may improve its tumour killing efficacy by preventing the induction of protumorigenic immune responses.

12.11.2014 Glitz and glamour are not words often used to describe science and mathematics. But once a year, celebrities from the science and showbiz world come together at the Breakthough Prizes, a glitzy television bash that honours scientists for their achievements. French life scientist Emmanuelle Charpentier was among this year’s winners.
