Understanding membrane fusion is paramount to the fabrication of biomimetic fusion systems, but replicating membrane fusion in vitro under neutral pH conditions without prior modification of lipid vesicles remains challenging. Here, the authors use the diphtheria toxin T-domain as a fusogenic tool, showing that it spontaneously interacts with anionic nanosized unilamellar vesicles at neutral pH in a non-disruptive manner, rendering membrane modifications unnecessary.
