True Molecular Scale Visualization of Variable Clustering Properties of Ryanodine Receptors
Cell Reports, 2018 Summary: Signaling nanodomains rely on spatial organization of proteins to allow controlled intracellular signaling. Examples include calcium release sites of cardiomyocytes where ryanodine receptors (RyRs) are clustered with their molecular partners ...

Probing active forces via a fluctuation-dissipation relation: Application to living cells [PDF]
, 2013 We derive a new fluctuation-dissipation relation for non-equilibrium systems with long-term memory. We show how this relation allows one to access new experimental information regarding active forces in living cells that cannot otherwise be accessed. For

An archaellum filament composed of two alternating subunits
Nature Communications, 2022 The archaellum is a molecular machine used by archaea to swim, consisting of an intracellular motor that drives the rotation of an extracellular filament composed of multiple copies of proteins named archaellins.

A functional family of fluorescent nucleotide analogues to investigate actin dynamics and energetics
Nature Communications, 2021 Actin polymerization provides force for vital processes of the eukaryotic cell, but our understanding of actin dynamics and energetics remains limited due to the lack of high-quality probes.

Analysis of Pneumocystis Transcription Factor Evolution and Implications for Biology and Lifestyle
mBio, 2023 Pneumocystis jirovecii kills hundreds of thousands of immunocompromised patients each year. Yet many aspects of the biology of this obligate pathogen remain obscure because it is not possible to culture the fungus in vitro independently of its host ...

An adaptive microscope for the imaging of biological surfaces
Light: Science & Applications, 2021 A smart-scanning fluorescence microscope adapts its scanning scheme to the curved surface of embryonic cell sheets. This results in a considerable reduction in light dose without deterioration of the images.
