This week’s articles explore the structural basis for nitrate sensing in bacteria, the importance of attenuating healing responses to reduce fibrosis and allergy, and the recruitment of chromatin silencing factors in X chromosome inactivation.

STRUCTURAL BIOLOGY

Bacterial sensing mechanism revealed

Gushchin et al. solved crystal structures of a transmembrane sensor protein to show how sensing of nitrate occurs in bacteria.

TISSUE REPAIR

Local macrophage clean-up

Minutti et al. and Bosurgi et al. showed that the cytokine interleukin-4 is required for macrophage-mediated tissue repair and remodeling (see also Bouchery and Harris).

X INACTIVATION

Polycomb steps to inactivate X

Almeida et al. redefined how polycomb recruitment in X inactivation occurs by showing that PRC1 initiates the recruitment of PRC2 in response to Xist RNA expression.
