Where antibiotic resistance mutations meet quorum-sensing
Rok Krašovec1, Roman V. Belavkin2, John A.D. Aston3, Alastair Channon4, Elizabeth Aston4, Bharat M. Rash1, Manikandan Kadirvel5,6, Sarah Forbes6, and Christopher G. Knight1
This article comments on work published by Krašovec et al. (Nat Comm, 2014), which found that the modulation of de novo mutation to promote antibiotic resistance depends on the density of the bacterial population and cell-cell interactions (rather than, for instance, the level of stress).
Sphingolipids and mitochondrial function, lessons learned from yeast
Pieter Spincemaille1, Bruno P.A. Cammue1,2 and Karin Thevissen1
This article reviews recent research showing that Saccharomyces cerevisiae is an invaluable model to investigate sphingolipids as signaling molecules in modulating mitochondrial function, but can also be used as a tool to further enhance our current knowledge on sphingolipids and mitochondria in mammalian cells.
Genome evolution in yeast reveals connections between rare mutations in human cancer
Xinchen Teng1,2 and J. Marie Hardwick2
This article comments on work published by Teng et al. (Mol Cell, 2013), which, using the yeast knockout collections, provides hard evidence that single gene deletions/mutations in most non-essential genes can drive the selection for cancer-like mutations.
Decoding the biosynthesis and function of diphthamide, an enigmatic modification of translation elongation factor 2 (EF2)
Raffael Schaffrath and Michael J. R. Stark
This article comments on work published by Uthman et al. (PLoS Genet, 2013), which suggests that Dph5 has a novel role as an EF2 inhibitor that affects cell growth when diphthamide synthesis is blocked or incomplete and shows that diphthamide promotes the accuracy of EF2 performance during translation.
Autophagy extends lifespan via vacuolar acidification
Christoph Ruckenstuhl1, Christine Netzberger1, Iryna Entfellner1, Didac Carmona-Gutierrez1, Thomas Kickenweiz1, Slaven Stekovic1, Christina Gleixner1, Christian Schmid1, Lisa Klug1, Ivan Hajnal1, Alice G. Sorgo1, Tobias Eisenberg1, Sabrina Büttner1, Guillermo Marin͂o2-4, Rafal Koziel5, Christoph Magnes6, Frank Sinner6,7, Thomas R. Pieber6,7, Pidder Jansen-Dürr5, Kai-Uwe Fröhlich1, Guido Kroemer2,3,8-11, and Frank Madeo1
This article comments on work published by Ruckenstuhl et al. (PLoS Genet, 2014), which uses Saccharomyces cerevisiae to show that autophagy promotes lifespan extension upon MetR and requires the subsequent stimulation of vacuolar acidification, while it is epistatic to the equally autophagy-dependent anti-aging pathway triggered by TOR1 inhibition or deletion.
When less is more: hormesis against stress and disease
Andreas Zimmermann1, Maria A. Bauer1, Guido Kroemer2-5, Frank Madeo1 and Didac Carmona-Gutierrez1
This article condenses the conceptual and potentially therapeutic importance of hormesis by providing a short overview of current evidence in favor of the cytoprotective impact of hormesis, as well as of its underlying molecular mechanisms.
Morphed and moving: TNFα-driven motility promotes cell dissemination through MAP4K4-induced cytoskeleton remodeling
Min Ma1,2 and Martin Baumgartner1
This article comments on work published by Ma and Baumgartner (PLoS Patho, 2014), which investigated Theileria parasite control of host cell motile properties in the context of inflammatory signaling.
Hormesis: a fundamental concept in biology
Edward J. Calabrese
This article addresses the concept of hormetic dose response, which describes the limits to which integrative endpoints can be modulated (i.e., enhanced or diminished) by pharmaceutical, chemical and physical means.
Prohibitins: emerging host targets of bacteria and viruses at the plasma membrane, mitochondria, and cytoplasm
June 3, 2026
Prohibitins are emerging as central host hubs exploited by bacteria and viruses to rewire signaling and mitochondrial dynamics. The current review discusses Prohibitins in host-pathogen interplay and their potential as novel anti-infective targets.
Outer membrane vesicles in Vibrio species: Roles in biofilm formation and pathogenesis
June 2, 2026
This review explores current knowledge on outer membrane vesicles (OMVs) in Vibrio species, highlighting their roles in pathogenesis, host interaction, and marine ecology; and identifies major knowledge gaps, outlining key methodological challenges and future prospects for OMV-based applications.
The mechanism of Tat-dependent protein translocation
May 15, 2026
This review integrates mechanistically relevant biochemical, molecular, and structural studies on Tat-dependent translocation of folded proteins into an in its molecular detail new comprehensive explanation of how the Tat system mediates protein transport.
Protein arginine methyltransferases in protozoan parasites: a new path for antiparasitic chemotherapy?
February 12, 2026
This review discusses the activity and the relevance of arginine methyltransferases for the survival of pathogenic kinetoplastids, apicomplexans and amoebas, and how these enzymes could be exploited as drug targets.
Gut microbiota and ankylosing spondylitis: current insights and future challenges
August 25, 2025
This review explores the growing role of gut microbiota in AS and its potential to reshape targeted treatment strategies and facilitate development of adjunct therapies to address disease onset and progression.
Advancements in vaginal microbiota, Trichomonas vaginalis, and vaginal cell interactions: Insights from co-culture assays
May 15, 2025
This review updates co-culture and co-incubation techniques for studying interactions of Lactobacillus spp., representing a pre-dominant member of the healthy vaginal microbiota; Candida spp., the most abundant yeast in the vagina, and T. vaginalis, responsible for the most widespread nonviral STI worldwide.
Influence of cervicovaginal microbiota on Chlamydia trachomatis infection dynamics
April 15, 2025
This review examines the complex interplay between the cervicovaginal microbiome, C. trachomatis infection, and host immune responses, highlighting the role of metabolites such as short-chain and long-chain fatty acids, indole, and iron in modulating pathogen survival and host defenses.
