This week’s articles describe the signals mediating gut microbe activation of T cells, skin patterning in development, and photosynthesis.

IMMUNOLOGY

Bacteria-selective gut T cells

Cervantes-Barragan et al. show that Lactobacillus reuteri induces a specific type of gut intraepithelial T cell through tryptophan catabolites that activate aryl hydrocarbon receptors.

DEVELOPMENT

Mechanosensation directs skin development

Shyer et al. discover that mechanical force establishes the patterning of skin follicles in developing chicks.

STRUCTURAL BIOLOGY

Structure and assembly of a plant supercomplex

Su et al. report that structural differences in the photosynthetic machinery enable plants to optimize photosynthesis under different light conditions.
