Septin Architecture Dictates Size-Dependent Diffusion Barriers on biomimetic Membranes

This study shows septins create size-dependent diffusion barriers on synthetic membranes by organizing into filaments, restricting the movement of membrane-bound objects with large cytosolic domains.

Unexpected softening of giant unilamellar vesicles by budding yeast septin filaments: a curvature dependent mechanism

The paper investigates how budding yeast septin filaments affect the mechanical properties of giant unilamellar vesicles (GUVs), finding that large GUVs become more deformable while small ones become less deformable due to septin-induced membrane reshaping.

Polarization MultiFocus Microscopy for volumetric super-resolution and orientation imaging of biofilaments

This paper introduces PolMFM, a method for simultaneous 3D localization and orientation imaging of single molecules, validated on actin filaments and chromatin in crickets.

SPITFIR(e): A supermaneuverable algorithm for restoring 2D-3D fluorescence images and videos,and background subtraction

The paper introduces SPITFIR(e), an algorithm for restoring 2D-3D fluorescence images/videos and subtracting background, demonstrating its effectiveness across multiple microscopy modalities.

Molecular basis of CTCF binding polarity in genome folding

The paper investigates how CTCF binding polarity influences chromatin loop formation by showing that CTCF positions cohesin but does not control its binding dynamics.
