Loss of Bacterial Cell Pole Stabilization in Caulobacter crescentus Sensitizes to Outer Membrane Stress and Peptidoglycan-Directed Antibiotics

Gerardo Turcatti, Marc Chambon, Julien Bortoli Chapalay

Rod-shaped bacteria frequently localize proteins to one or both cellpoles in order to regulate processes such as chromosome replication or polar organ-elle development. However, the roles of polar factors in responses to extracellularstimuli have been gene ...

Tp63-expressing adult epithelial stem cells cross lineages boundaries revealing latent hairy skin competence

Yann Barrandon, Ariane Rochat, Paola Bonfanti, Stéphanie Claudinot, Christèle Gonneau

The formation of hair follicles, a landmark of mammals, requires complex mesenchymal-epithelial interactions and it is commonly believed that embryonic epidermal cells are the only cells that can respond to hair follicle morphogenetic signals in vivo. Here ...

Moire Flat Bands in Twisted Double Bilayer Graphene

Oleg Yazyev, Quansheng Wu, Seyedeh Fatemeh Haddadi Givi

We investigate twisted double bilayer graphene (TDBG), a four-layer system composed of two AB-stacked graphene bilayers rotated with respect to each other by a small angle. Our ab initio band structure calculations reveal a considerable energy gap at the c ...

Role of Activin-A signaling in melanoma

Olivier Andreas Dubey

Cutaneous melanomas arise from transformed skin melanocytes. While accounting for only 1% of skin malignancies, melanoma is responsible for the majority of skin cancer-related deaths. Owing to lifestyle changes and increased exposure to sunlight, melanoma ...

Using NanoSIMS coupled with microfluidics to visualize the early stages of coral infection by Vibrio coralliilyticus

Anders Meibom, Isabelle Domart-Coulon, Emma Mary Gibbin

Background: Global warming has triggered an increase in the prevalence and severity of coral disease, yet little is known about coral/pathogen interactions in the early stages of infection. The point of entry of the pathogen and the route that they take on ...

A balancing act between stratification and EMT in cultured human thymic epithelial cells

Matteo Pluchinotta

The thymus is the primary organ for T cell differentiation and maturation. Its stroma forms a characteristic sponge-like 3D structure mainly composed of thymic epithelial cells. Despite of this unconventional epithelial architecture, TECs express markers a ...

From the early steps of whisker formation to its evolutionary disappearance: the (curious) case of Prdm1 and its regulation

Pierluigi Giuseppe Manti

Whiskers (also known as vibrissae) are sensory organs that are thought to have first appeared in Therapsida, a group of synapsids that includes mammals and evolutionary ancestors like the Thrinaxodon(1). They are highly conserved among mammals to the notab ...

Capturing epidermal stemness

Andrea Zaffalon

Regenerative medicine aims to replace or regenerate tissues or organs to re-establish their normal function. In 1975, Rheinwald and Green developed a technique to isolate and amplify epidermal stem cells. Their discovery led to the development of cultured ...

Chronic inflammation imposes aberrant cell fate in regenerating epithelia through mechanotransduction

Matthias Lütolf, Freddy Radtke, Georg Fantner, Yann Barrandon, Pascal Damian Odermatt, Craig Nowell, Sylke Höhnel

Chronic inflammation is associated with a variety of pathological conditions in epithelial tissues, including cancer, metaplasia and aberrant wound healing. In relation to this, a significant body of evidence suggests that aberration of epithelial stem and ...
