Reconfigurable Microenvironments Uncover Mechano‐Sensing Timescales and Direct Cell Polarity

Advanced Functional Materials, EarlyView.
A synthetic DNA‐crosslinked cell culture matrix enables control over the mechanical microenvironment surrounding cells. Independent tuning of stiffness and stress relaxation uncovers distinct timescales of mechano‐sensing that regulate cell behavior.

Human cyclophilin 40 unravels neurotoxic amyloids.

PLoS Biology, 2017
The accumulation of amyloidogenic proteins is a pathological hallmark of neurodegenerative disorders. The aberrant accumulation of the microtubule associating protein tau (MAPT, tau) into toxic oligomers and amyloid deposits is a primary pathology in ...

Multifunctional Protein Eutectogels Based on Polyphenolic: Zwitterionic Low‐Transition‐Temperature Mixtures

Advanced Functional Materials, EarlyView.
This work presents the first example of multifunctional protein eutectogels based on a tannic acid: betaine low‐transition‐temperature mixture, exhibiting elastomeric behavior, strong adhesion to various substrates, including biological tissues, and notable anti‐inflammatory properties derived from the natural polyphenol and zwitterion.

Transport by molecular motors in the presence of static defects [PDF]

, 2009
The transport by molecular motors along cytoskeletal filaments is studied theoretically in the presence of static defects. The movements of single motors are described as biased random walks along the filament as well as binding to and unbinding from the
