Use of chiral cell shape to ensure highly directional swimming in trypanosomes
PLoS Comput. Biol., 2017 Swimming cells typically move along a helical path or undergo longitudinal rotation as they swim, arising from chiral asymmetry in hydrodynamic drag or propulsion bending the swimming path into a helix.

The nucleus measures shape changes for cellular proprioception to control dynamic cell behavior
Science, 2020 The nucleus makes the rules Single cells continuously experience and react to mechanical challenges in three-dimensional tissues. Spatial constraints in dense tissues, physical activity, and injury all impose changes in cell shape.

Nuclear shapes are geometrically determined by the excess surface area of the nuclear lamina
Frontiers in Cell and Developmental Biology, 2023 Introduction: Nuclei have characteristic shapes dependent on cell type, which are critical for proper cell function, and nuclei lose their distinct shapes in multiple diseases including cancer, laminopathies, and progeria.

Cell shape information is transduced through tension-independent mechanisms
Nature Communications, 2017 The shape of a cell within tissues can represent the history of chemical and physical signals that it encounters, but can information from cell shape regulate cellular phenotype independently?

HLA-DR15 Molecules Jointly Shape an Autoreactive T Cell Repertoire in Multiple Sclerosis
Cell, 2020 Summary The HLA-DR15 haplotype is the strongest genetic risk factor for multiple sclerosis (MS), but our understanding of how it contributes to MS is limited.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Asymptomatic infection poses a significant risk for children undergoing hematopoietic stem cell transplantation (HSCT). Pre‐transplant surveillance computed tomography (CT) is commonly used to identify occult infection, though its diagnostic yield remains uncertain.

Multistability and dynamic transitions of intracellular Min protein patterns
Molecular Systems Biology, 2016 Cells owe their internal organization to self‐organized protein patterns, which originate and adapt to growth and external stimuli via a process that is as complex as it is little understood. Here, we study the emergence, stability, and state transitions

Epithelial tricellular junctions act as interphase cell shape sensors to orient mitosis
Nature, 2016 The orientation of cell division along the long axis of the interphase cell—the century-old Hertwig’s rule—has profound roles in tissue proliferation, morphogenesis, architecture and mechanics.

Getting bacterial cells into shape
eLife, 2023 The conformational state of a structural protein in bacteria can vary, depending on the concentration level of potassium ions or the nucleotide bound to it.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.
