Energy-harnessing problem solving of primordial life: Modeling the emergence of catalytic host-nested parasite life cycles

Christian Iseli

All life forms on earth ultimately descended from a primordial population dubbed the last universal common ancestor or LUCA via Darwinian evolution. Extant living systems share two salient functional features, a metabolism extracting and transforming energ ...

SARS-CoV-2 hijacks a cell damage response, which induces transcription of a more efficient Spike S-acyltransferase

Didier Trono, Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Béatrice Kunz, Francisco De Magalhães Sarmento R De Mesquita, Lucie Josepha Marie Bracq, Joana Carlevaro Fita, Audrey Geneviève Chuat, Nattawadee Panyain

SARS-CoV-2 infection requires Spike protein-mediated fusion between the viral and cellular membranes. The fusogenic activity of Spike depends on its post-translational lipid modification by host S-acyltransferases, predominantly ZDHHC20. Previous observati ...

Preexisting Heterogeneity of Inducible Nitric Oxide Synthase Expression Drives Differential Growth of Mycobacterium tuberculosis in Macrophages

John McKinney, Ophélie Rutschmann, Chiara Toniolo

Mycobacterium tuberculosis infection is initiated by the inhalation and implantation of bacteria in the lung alveoli, where they are phagocytosed by macrophages. Even a single bacterium may be sufficient to initiate infection. Thereafter, the clinical outc ...

Engineering Agrobacterium tumefaciens Adhesion to Target Cells

Alexandre Louis André Persat, Xavier Jean-Yves Pierrat, Jeremy Pak Hei Wong, Alix Kim Lan Pham

Agrobacterium tumefaciens is a plant pathogen commonly repurposed for genetic modification of crops. Despite its versatility, it remains inefficient at transferring DNA to many hosts, including to animal cells. Like many pathogens, physical contact between ...

Novel High-Throughput Fluorescence-Based Assay for the Identification of Nematocidal Compounds That Target the Blood-Feeding Pathway

Gerardo Turcatti, Marc Chambon, Anthony Marchand, Nicola Harris, Tiffany Babette Angélique Bouchery, Mati André Marie Moyat

Hookworm infections cause a neglected tropical disease (NTD) affecting ~740 million people worldwide, principally those living in disadvantaged communities. Infections can cause high morbidity due to their impact on nutrient uptake and their need to feed o ...

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 ...

A Phylogeny-aware GWAS Framework to Correct for Heritable Pathogen Effects on Infectious Disease Traits

Jacques Fellay, Christian Axel Wandall Thorball

Infectious diseases are particularly challenging for genome-wide association studies (GWAS) because genetic effects from two organisms (pathogen and host) can influence a trait. Traditional GWAS assume individual samples are independent observations. Howev ...

Two defence systems eliminate plasmids from seventh pandemic Vibrio cholerae

Melanie Blokesch, David William Adams, Milena Jadwiga Jaskolska

Horizontal gene transfer can trigger rapid shifts in bacterial evolution. Driven by a variety of mobile genetic elements—in particular bacteriophages and plasmids—the ability to share genes within and across species underpins the exceptional adaptability o ...

Multidisciplinary Investigation of the Gut-Brain Ecosystem in a Model of Alzheimer's Disease

Arielle Louise Planchette

The search for an understanding of the causal elements that lead to neurodegenerative diseases has motivated researchers for decades. Today, Alzheimer's disease is the most prevalent form of dementia and affects approximately fifty million people worldwide ...

Mechanism ofcyclic beta-glucan export by ABC transporter Cgt of Brucella

Henning Paul-Julius Stahlberg, Dongchun Ni, Na Wu

Polysaccharides play critical roles in bacteria, including the formation of protective capsules and biofilms and establishing specific host cell interactions. Their transport across membranes is often mediated by ATP-binding cassette (ABC) transporters, wh ...
