Kind: research · Impact: low

## In brief

- WASH drives actin-dependent lysosomal dynamics in neutrophils, according to the study.
- The authors report that WASH regulates late phagosomal maturation through STX19-mediated lysosomal fusion.
- The work links this pathway to bacterial killing by neutrophils.

## Why it matters

It clarifies how actin regulates the maturation of phagosomes and the killing of microbes in neutrophils, a basic mechanism of innate immunity that cell biologists and immunologists can build on.
