Inhibition of Zika virus by Wolbachia in Aedes aegypti
Eric Pearce Caragata, Heverton Leandro Carneiro Dutra and Luciano Andrade Moreira
This article comments on work published by Dutra et al. (Cell Host Microbe, 2016), which investigated the potential of Wolbachia infections in Aedes aegypti to restrict infection and transmission of Zika virus.
Syphilis: Re-emergence of an old foe
Lola V. Stamm
Syphilis is caused by infection with Treponema pallidum subsp. pallidum, a not-yet-cultivable spiral-shaped bacterium that is usually transmitted by sexual contact with an infected partner or by an infected pregnant woman to her fetus. This review provides insights into the etiology, epidemiology, clinical manifestation, diagnosis, treatment and prevention of syphilis.
Trichomoniasis – are we giving the deserved attention to the most common non-viral sexually transmitted disease worldwide?
Camila Braz Menezes, Amanda Piccoli Frasson, Tiana Tasca
Trichomonas vaginalis is the etiologic agent of trichomoniasis, the most common non-viral sexually transmitted disease (STD) in the world. This article contributes to claim the attention of public health policies to control this STD.
House of cellulose – a new hideout for drug tolerant Mycobacterium tuberculosis
Ashwani Kumar
This article comments on work published by Trivedi et al. (Nat Commun, 2016), which shows that Mycobacterium tuberculosis cells organise themselves into biofilms in response to intracellular thiol reductive stress.
Antibiotic use in childhood alters the gut microbiota and predisposes to overweight
Katri Korpela and Willem M de Vos
This article comments on work published by Korpela et al. (Nat Commun, 2016), which investigates the correlation between the use of antibiotics in early life and the excessive weight gain in later childhood.
Evidence for the hallmarks of human aging in replicatively aging yeast
Georges E. Janssens, Liesbeth M. Veenhoff
Recently, efforts have been made to characterize the hallmarks that accompany and contribute to the phenomenon of aging, as most relevant for humans. Remarkably, studying the finite lifespan of the single cell eukaryote budding yeast has been paramount for our understanding of aging. Here, we compile observations from literature over the past decades of research on replicatively aging yeast to highlight how the hallmarks of aging in humans are present in yeast.
Bacterial outer membrane vesicle biogenesis: a new mechanism and its implications
Sandro Roier, Franz G. Zingl, Fatih Cakar, and Stefan Schild
This article comments on work published by Roier et al. (Nat Commun, 2016), which proposes a novel and highly conserved bacterial outer membane vesicle biogenesis mechanism based on phospholipid accumulation in the outer leaflet of the outer membrane.
A plant Bcl-2-associated athanogene is proteolytically activated to confer fungal resistance
Mehdi Kabbage1, Ryan Kessens1 and Martin B. Dickman2
This article comments on work published by Li et al. (Plant Cell, 2016), which focuses on the role of Bcl-2-associated athanogene 6 (BAG6) in plant innate immunity, showing that BAG6 plays a key role in basal plant defense against fungal pathogens.
Methodologies for in vitro and in vivo evaluation of efficacy of antifungal and antibiofilm agents and surface coatings against fungal biofilms
June 14, 2018
This article highlights the critical importance of accurate susceptibility testing methods and the discovery of novel antifungal and antibiofilm agents in combating invasive fungal infections associated with biofilm formation on medical devices, thereby emphasizing the need for advancements in medical mycology research to address these complex diseases.
Shepherding DNA ends: Rif1 protects telomeres and chromosome breaks
May 17, 2018
This review discusses the conserved mechanisms cells have evolved to protect DNA ends at chromosomal termini and DNA double-strand breaks (DSBs), focusing on the protein Rif1’s roles in telomere homeostasis and DSB repair in eukaryotes. It highlights the intriguing connection between Rif1's involvement in both telomere maintenance and DSB repair, and suggests that excluding end-processing factors may underlie Rif1's diverse biological functions at telomeres and chromosome breaks.
The CRISPR conundrum: evolve and maybe die, or survive and risk stagnation
May 16, 2018
In this article García-Martínez et al. cover how the model bacterium Escherichia coli deals with CRISPR-Cas to tackle the major dilemma of evolution versus survival.
pH homeostasis links the nutrient sensing PKA/TORC1/Sch9 ménage-à-trois to stress tolerance and longevity
January 12, 2018
In this article, Deprez et al. discuss accumulating evidence indicates that pH homeostasis plays a prominent role in the determination of ageing and longevity, thereby providing new perspectives and avenues to explore the underlying molecular mechanisms.
Guidelines and recommendations on yeast cell death nomenclature
January 1, 2018
In this review, we propose unified criteria for the definition of accidental, regulated, and programmed forms of cell death in yeast based on a series of morphological and biochemical criteria. Specifically, we provide consensus guidelines on the differential definition of terms including apoptosis, regulated necrosis, and autophagic cell death, as we refer to additional cell death routines that are relevant for the biology of yeast.
Ras signalling in pathogenic yeasts
December 18, 2017
In this article Pentland et al. review the roles of Ras protein function and signalling in the major human yeast pathogens Candida albicans and Cryptococcus neoformans and discuss the potential for targeting Ras as a novel approach to anti-fungal therapy.
The integrated stress response in budding yeast lifespan extension
October 24, 2017
This article summarizes how the budding yeast Saccharomyces cerevisiae has been instrumental in unraveling the molecular and cellular determinants of aging, and how the induction of cellular stress responses has been associated with experimental lifespan extension, thus underscoring the value of yeast as a model for developing potential aging therapies for humans.
Exacerbating and reversing lysosomal storage diseases: from yeast to humans
August 25, 2017
This article summarizes the use of yeast models in advancing our understanding of lysosomal storage diseases (LSDs), where they have been instrumental in researching LSD mechanisms, screening for therapeutic compounds, and exploring genetic and gene-environment interactions relevant to diseases like Batten disease, cystinosis, and Niemann-Pick type C disease, as well as their connection to broader health issues such as viral infections and obesity.
