Hierarchical Protofilament Intertwining Rules the Formation of Mixed-Curvature Amyloid Polymorphs

Giovanni Dietler, Henning Paul-Julius Stahlberg, Meltem Tatli, Francesco Simone Ruggeri, Jiangtao Zhou, Salvatore Assenza, Raffaele Mezzenga

Amyloid polymorphism is a hallmark of almost all amyloid species, yet the mechanisms underlying the formation of amyloid polymorphs and their complex architectures remain elusive. Commonly, two main mesoscopic topologies are found in amyloid polymorphs cha ...

Towards understanding centriole elimination

Nils Kalbfuss

Centrioles are microtubule-based structures crucial for forming flagella, cilia and centrosomes. Through these roles, centrioles are critical notably for proper cell motility, signalling and division. Recent years have advanced significantly our understand ...

Cellularization across eukaryotes: Conserved mechanisms and novel strategies

Omaya Pierre Dudin

Many eukaryotes form multinucleated cells during their devel-opment. Some cells persist as such during their lifetime, others choose to cleave each nucleus individually using a specialized cytokinetic process known as cellularization. What is cellula-rizat ...

Two antagonistic response regulators control Pseudomonas aeruginosa polarization during mechanotaxis

Alexandre Louis André Persat, Lorenzo Anton-Louis Talà, Xavier Jean-Yves Pierrat, Joanne Netter Engel, Marco Julian Kühn

The opportunistic pathogen Pseudomonas aeruginosa adapts to solid surfaces to enhance virulence and infect its host. Type IV pili (T4P), long and thin filaments that power surface-specific twitching motility, allow single cells to sense surfaces and contro ...

Refining S-acylation: Structure, regulation, dynamics, and therapeutic implications

Françoise Gisou van der Goot Grunberg, Muhammad Umair Anwar

S-acylation is one of the most frequent posttranslational modifications that regulates diverse cellular processes. Anwar and van der Goot discuss the complexity and disease implications of this highly regulated reversible lipidation. With a limited number ...

Micro- or nanostructured optical element

Niels Quack, Dorian Giraud Herle

A micro- or nanostructured optical element (1) is proposed comprising: a membrane (3) with an array of holes (5), the membrane (3) comprising a membrane light wave facing surface; an array of pillars (7) sized and shaped such that a respective pillar (7) i ...

Characterization of Pseudomonas aeruginosa mechanosensing through label-free imaging of type IV pili

Lorenzo Anton-Louis Talà

Bacteria are ubiquitously found in all sorts of environment. They're found in the ocean, soil, or even in our guts or on our skin. Independently of their niche, they can transition from a planktonic state were they freely swim in an aqueous environment to ...

Coral holobiont cues prime Endozoicomonas for a symbiotic lifestyle

Nils Rädecker, Claudia Isabella Pogoreutz, Gabriela Hannah Holligan Perna

Endozoicomonas are prevalent, abundant bacterial associates of marine animals, including corals. Their role in holobiont health and functioning, however, remains poorly understood. To identify potential interactions within the coral holobiont, we character ...

Fluorescent D-Amino Acids for Super-resolution Microscopy of the Bacterial Cell Wall

Suliana Manley, Luc Reymond, Chen Zhang, Ophélie Rutschmann, Willi Leopold Stepp, Faustine Ambroisine Charline Ryckebusch, Juliette Griffie, Jiangtao Qiao

Fluorescent D-amino acids (FDAAs) have previ-ously been developed to enable in situ highlighting of locations of bacterial cell wall growth. Most bacterial cells lie at the edge of the diffraction limit of visible light; thus, resolving the precise details ...

Highly motile nanoscale magnetic artificial cilia

Yves Bellouard, Tanveer Ul Islam

Among the many complex bioactuators functioning at different scales, the organelle cilium represents a fundamental actuating unit in cellular biology. Producing motions at submicrometer scales, dominated by viscous forces, cilia drive a number of crucial b ...
