Engineering synthetic adhesins for biophysical investigation and rewiring of host-microbe interactions

Xavier Jean-Yves Pierrat

Host attachment is often a critical step in the onset of pathogenesis. To attach to host cells, bacteria have evolved a range of adhesins that bind to specific receptors. Some of these adhesins have been thoroughly characterized using biochemical technique ...

Akt Is S-Palmitoylated: A New Layer of Regulation for Akt

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

The protein kinase Akt/PKB participates in a great variety of processes, including translation, cell proliferation and survival, as well as malignant transformation and viral infection. In the last few years, novel Akt posttranslational modifications have ...

Palmitoylated acyl protein thioesterase APT2 deforms membranes to extract substrate acyl chains

Matteo Dal Peraro, Françoise Gisou van der Goot Grunberg, Florence Pojer, Laurence Gouzi Abrami, Maria Josefina Marcaida Lopez, Francisco De Magalhães Sarmento Ribeiro De Mesquita, Martina Audagnotto, Patrick Alain Sandoz, Sylvia Ho, Giulia Fonti, Muhammad Umair Anwar

Acyl protein thioesterase APT2 interacts with membranes via its charged beta-tongue, becomes palmitoylated by ZDHHC3/7 and deforms the bilayer to extract substrate acyl chains. APT2 deacylation leads to its membrane release and degradation. ...

Disruption of mitochondrial redox homeostasis by enzymatic activation of a trialkylphosphine probe

Pablo Rivera Fuentes, Jade Noémie Nam Nguyen

Redox homeostasis is essential for cell function and its disruption is associated with multiple pathologies. Redox balance is largely regulated by the relative concentrations of reduced and oxidized glutathione. In eukaryotic cells, this ratio is different ...

Nanomechanical bio-sensing for fast and reliable detection of viability and susceptibility of microorganisms

Giovanni Dietler, Sandor Kasas, María Inés Villalba, Leonardo Venturelli, Raphaël Foschia

The metabolic activity of living organisms results in cellular motion on a nanometric scale that can be efficiently detected by micro- and nano- fabricated sensors. Quartz crystal microbalance and atomic force microscopy (AFM) inspired techniques have rece ...

Analysis and Modeling of the Dynamics of Traction Forces during Cell Polarization and their Role in the Organization of Edge Activity

Zeno Messi

The capacity to break symmetry and organize activity to move directionally is a fundamental property of eukaryotic cells. To explain the organization of cell-edge activity, models commonly rely on front-to-back gradients of functional components or regulat ...

Microfluidics and cell-free synthetic biology in the development of new diagnostic and therapeutic platforms

Grégoire Michielin

In phenylketonuria, absence or malfunction of the phenylalanine hydroxylase enzyme results in toxic accumulation of phenylalanine in the body. An injectable recombinant enzyme therapy was recently approved and has the potential to improve the quality of li ...

Organisation and dynamics of mitochondria and their RNA

Timo Henry René Rey

The organisation of molecules into dynamic cells, and collaboration of many of those cells over a billion years led to the evolution of human life. During the last century, biologists then began to unravel the marvels of cellular organisation with ever inc ...

Single-cell lipidomics reveals a role for cell-to-cell sphingolipid heterogeneity in fibroblast activation

Laura Capolupo

Cell-to-cell variability plays a key role in tissue patterning by setting initial asymmetry that primes cell fate decisions. Fluctuations in the activity of regulatory molecules can commit individual cells to divergent differentiation pathways, and cell-to ...

Imaging Cu2+ binding to charged phospholipid membranes by high-throughput second harmonic wide-field microscopy

Sylvie Roke, David Roesel, Seonwoo Lee

The interaction of divalent copper ions (Cu2+) with cell membranes is crucial for a variety of physiological processes of cells, such as hormone synthesis and cellular energy production. These interactions would not be possible without membrane hydration. ...
