How Vibrio cholerae adapts to the environment: from cell shape transitions to antagonistic behavior

Leonardo Filipe Lemos Rocha

The bacterium Vibrio cholerae is the causative agent of the diarrheal disease cholera, which affects millions of people every year. Apart from being a human pathogen, V. cholerae is also a common member of aquatic habitats. Whilst the mechanism that allow ...

Ammonium is the preferred source of nitrogen for planktonic foraminifer and their dinoflagellate symbionts

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

The symbiotic planktonic foraminiferaOrbulina universainhabits open ocean oligotrophic ecosystems where dissolved nutrients are scarce and often limit biological productivity. It has previously been proposed thatO. universameets its nitrogen (N) requiremen ...

Endothelial extracellular vesicles contain protective proteins and rescue ischemia-reperfusion injury in a human heart-on-chip

Maartje Martina Cornelia Bastings

Extracellular vesicles (EVs) derived from various stem cell sources induce cardioprotective effects during ischemia-reperfusion injury (IRI). These have been attributed mainly to the antiapoptotic, proangiogenic, microRNA (miRNA) cargo within the stem cell ...

Influenza A viruses use multivalent sialic acid clusters for cell binding and receptor activation

Suliana Manley, Christian Sieben

Influenza A virus (IAV) binds its host cell using the major viral surface protein hemagglutinin (HA). HA recognizes sialic acid, a plasma membrane glycan that functions as the specific primary attachment factor (AF). Since sialic acid alone cannot fulfill ...

Bacterial cell cycle dynamics: size regulation during exponential growth and role of polyphosphate during starvation response

Aster Louis K Vanhecke

Bacteria are the most diverse and abundant kingdom of life and have adapted to survive and thrive in habitats around the globe. When provided with ample nutrients they grow and divide at staggering rates, increasing their population exponentially. Upon nut ...

Cellular ultrastructure in benthic foraminifera: general observations and focus on kleptoplasts.

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Research of the past few decades has revealed a great variability of metabolisms (e.g. adaptation to different microhabitats, feeding strategies, symbiosis, survival to stressful conditions) among benthic foraminiferal species. This metabolic variety is re ...

Dispositif et procédé pour l'évaluation de la contraction cellulaire

Boris Hinz, Pierre Jean Arnould Wipff

A method for assessing cell contraction includes adhering contractile cells to an oxidized and cellular adhesion activated surface of a biocompatible silicone elastomer film. The biocompatible silicone elastomer film allows the cells to contract and wrinkl ...

An Amidase_3 domain-containing N-acetylmuramyl-L-alanine amidase is required for mycobacterial cell division

Neeraj Dhar, Ashima Bhaskar, Dong Li

Mycobacteria possess a multi-layered cell wall that requires extensive remodelling during cell division. We investigated the role of an amidase_3 domain-containing N-acetylmuramyl-L-alanine amidase, a peptidoglycan remodelling enzyme implicated in cell div ...
