A constricted mitochondrial morphology optimizes respiration.

The paper identifies a new mitochondrial morphology in yeast called Ringo that enhances respiration by ensuring proper OXPHOS complex assembly.

A polarized cell system amenable to subcellular resolution imaging of influenza virus infection

This paper describes a 3D cell culture method to study influenza virus infection in polarized cells with subcellular resolution.

HIV-1 hijacks the cell extracellular matrix to spread collectively and efficiently between T lymphocytes

This study shows HIV-1 spreads between T lymphocytes via extracellular matrix (ECM)-clustered viral particles, enhancing transmission efficiency and resistance to antiretroviral treatment and antibodies.

SARS-CoV-2 infection damages airway motile cilia and impairs mucociliary clearance

This study shows SARS-CoV-2 infection damages airway motile cilia and impairs mucociliary clearance, potentially facilitating viral spread to the deeper lung.

Intraflagellar transport during the assembly of flagella of different length in Trypanosoma brucei isolated from tsetse flies

This study examines how Trypanosoma brucei modulates flagellum length during development in tsetse flies, finding a correlation between intraflagellar transport protein levels and flagellum length.

Timing and original features of flagellum assembly in trypanosomes during development in the tsetse fly

This paper investigates flagellum assembly in Trypanosoma brucei during differentiation in tsetse flies, revealing unique structural and temporal features distinct from procyclic cells.

Bidirectional intraflagellar transport is restricted to two sets of microtubule doublets in the trypanosome flagellum

This study identifies two distinct IFT tracks in trypanosome flagella using microscopy, showing bidirectional transport on parallel lines and dynamic conversion of anterograde to retrograde trains.

Adhesion to nanofibers drives cell membrane remodeling through 1D wetting

This study identifies a novel physical mechanism, 1D wetting, by which Neisseria meningitidis drives plasma membrane remodeling on nanofibers independent of F-actin.
