WASH orchestrates phagosomal maturation and bacterial killing in neutrophils through syntaxin 19-mediated lysosomal fusion
Nature · By Elsa Meneses-Salas ·
The 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.
