World Immune Regulation Meeting (WIRM)--III: special focus on regulatory and effector mechanisms.

Immune regulation is one of the most important topics in basic and clinical research, and IL-17-producing T helper cells (Th17) cells and regulatory T-cells (Tregs) are at the forefront of immunological research. The annual World Immune Regulation Meeting gathers some of the best experts in this field, and this year's meeting included presentations on new regulators of Th17 differentiation, novel mechanisms of immunosuppression by Tregs, and innovative systems for the ex vivo generation of Tregs. Novel targets for allergic inflammation were also discussed.
