Woronin bodies move dynamically and bidirectionally by hitchhiking on early endosomes in Aspergillus nidulans

The paper shows Woronin bodies in Aspergillus nidulans move by hitchhiking on early endosomes, and this movement is dependent on PxdA, though not essential for their septal function.

Cytoplasmic dynein-1 cargo diversity is mediated by the combinatorial assembly of FTS-Hook-FHIP complexes

The paper investigates how dynein cargo diversity is achieved through the combinatorial assembly of FTS-Hook-FHIP complexes in human cells.

Optimizing microtubule arrangements for rapid cargo capture

The paper models diffusive cargo capture along microtubules in tubular cells, showing that optimal microtubule arrangements with a single long microtubule and broad plus-end distribution minimize capture times.

Wnt-mediated interactions of tumor-initiating cells with a macrophage niche drive skin tumor formation

The paper identifies a macrophage-tumor-initiating cell niche regulated by Wnt signaling that drives skin tumor formation and maintenance.

PxdA interacts with the DipA phosphatase to regulate endosomal hitchhiking of peroxisomes

The paper identifies PxdA as a specific molecular linker for peroxisome hitchhiking on early endosomes in A. nidulans and reveals DipA as a regulator of this process.

Hitching a Ride: Mechanics of Organelle Transport Through Linker-Mediated Hitchhiking

The paper develops a quantitative model to study hitchhiking transport of organelles in fungal hyphae, showing how linker proteins and cytoskeletal tracks affect transport efficiency.

Chlamydomonas reinhardtii formin FOR1 and profilin PRF1 are optimized for acute rapid actin filament assembly

This study identifies FOR1 and PRF1 in Chlamydomonas reinhardtii as key regulators of rapid F-actin assembly for fertilization tubule formation.
