In Fig. 1a of this Article, the y-axis label should read ‘Fat to lean mass (ratio)’ rather than ‘Lean to fat mass (ratio)’. In addition, the number inside the top left flow cytometry plot in Fig. 4j should be 47.2 instead of 57.5. In the Methods subsection ‘Mice’, the strain IL10GFP should be linked to Jax stock no. 008379 rather than Jax stock no. 014530, and the strain Il33GFP should be associated with ref. 1 (below) rather than with Jax stock no. 002650. This new reference has been added as ref. 36 in the original Article and the subsequent references have been renumbered accordingly. The original Article has been corrected online.
