![immune, cell,](https://cdn.mos.cms.futurecdn.net/HCq4ru9zwbodKtA5foLYzV-1000-80.jpg)
When it comes down to it, it's your immune system versus the world. From "innate" immunity — which protects your body against basic threats — to "adaptive" immunity, which homes in on specific targets, your immune system has you covered. Sometimes, however, your immune system can turn against you, leading to autoimmune diseases. To keep up with all things immune, check here for the latest news.

Master regulator of inflammation found — and it's in the brain stem
By Emily Cooke published
Research in mice suggests that specific neurons within the brain stem act like the dial on a thermostat — fine-tuning inflammation as and when required.
