Integrins in disguise – mechanosensors in Saccharomyces cerevisiae as functional integrin analogues
Tarek Elhasi1 and Anders Blomberg1
This article shows that although yeast lack integrin-like proteins, they possess WSC- and MID-type mechanosensors that functionally resemble integrins in animal cells, playing a role in sensing external mechanical stimuli and activating the conserved PKC1-SLT1 cell wall integrity pathway, with potential implications for understanding mechanosensing in yeast biology.
Bacterial maze runners reveal hidden diversity in chemotactic performance
M. Mehdi Salek1,#, Francesco Carrara1,#, Vicente Fernandez1 and Roman Stocker1
This article comments on work published by Salek et al. (Nat Commun, 2019), which combined microfluidic experiments with mathematical modeling to demonstrate that even in clonal populations, bacteria are individuals with different abilities to climb chemical gradients.
Laundry and textile hygiene in healthcare and beyond
Dirk P. Bockmühl1, Jan Schages1 and Laura Rehberg1
This article shows that while institutional laundering is regulated to ensure hygiene, the trend towards energy-efficient washing at lower temperatures raises concerns about the antimicrobial efficacy of domestic laundering, with a focus on addressing microbial contamination in both clinical and home settings.
Bacterial pathogens under high-tension: Staphylococcus aureus adhesion to von Willebrand factor is activated by force
Felipe Viela1, Pietro Speziale2,3, Giampiero Pietrocola2 and Yves F. Dufrêne1,4
This article comments on work published by Viela et al (mBio, 2019), which shows that the bacterial cell surface protein A to the large plasma glycoprotein von Willebrand factor interaction is tightly regulated by mechanical force.
Yeast AP-1 like transcription factors (Yap) and stress response: a current overview
Claudina Rodrigues-Pousada1, Frédéric Devaux2, Soraia M. Caetano1, Catarina Pimentel1, Sofia da Silva1, Ana Carolina Cordeiro1 and Catarina Amaral1
This review summarizes current understanding of the eight Yap transcription factors in Saccharomyces cerevisiae, detailing their activation by specific stress conditions and discussing their function and evolution across various fungal species.
Septin clearance from the division site triggers cytokinesis in budding yeast
Davide Tamborrini1 and Simonetta Piatti1
This article comments on work published by Tamborrini et al (Nat Commun., 2019), which shows that septin displacement during splitting is an essential prerequisite for contractile actomyosin ring constriction during mitosis.
The influence of the microbiota on immune development, chronic inflammation, and cancer in the context of aging
Taylor N. Tibbs1,#, Lacey R. Lopez1,#, and Janelle C. Arthur1,2,3
This article shows that the microbiota is crucial for immune system development and that its relationship with the immune system during aging and the pathogenesis of age-related diseases, including cancer, needs further research to inform disease treatment and prevention.
Ser/Thr protein phosphatases in fungi: structure, regulation and function
Joaquín Ariño1, Diego Velázquez1 and Antonio Casamayor1
In this work we present the members of this family in S. cerevisiae and other fungal species, and review the most recent findings concerning their regulation and the roles they play in the most diverse aspects of cell biology.
Antibiotic use in childhood alters the gut microbiota and predisposes to overweight
June 20, 2016
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.
Bacterial outer membrane vesicle biogenesis: a new mechanism and its implications
May 10, 2016
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
April 16, 2016
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.
Chemical proteomics approach reveals the direct targets and the heme-dependent activation mechanism of artemisinin in Plasmodium falciparum using an activity-based artemisinin probe
April 5, 2016
This article comments on work published by Wang et al. (Nat Commun, 2014), which provides insights into the mode-of-action of artemisinin and its specificity against malaria parasites.
Translational repression in malaria sporozoites
April 5, 2016
This article comments on work published by Zhang et al. (PLoS Pathog, 2016), which summarizea recent advances in the translational repression of gene expression in the malaria sporozoite.
When and where? Pathogenic Escherichia coli differentially sense host D-serine using a universal transporter system to monitor their environment
March 31, 2016
This article comments on work published by Connolly et al. (PLoS Pathog, 2016), which describes the discovery of a functional and previously uncharacterized D-serine uptake system in E. coli.
The bacterial cell cycle checkpoint protein Obg and its role in programmed cell death
March 16, 2016
This article comments on work published by Dewachter et al. (mBio, 2015), which identified a programmed cell death mechanism in Escherichia coli that is triggered by a mutant isoform of the essential GTPase ObgE.
Control of the gut microbiome by fecal microRNA
March 9, 2016
This article comments on work published by Liu et al. (Cell Host & Microbe, 2016), which identifies miRNAs in gut lumen and feces of both mice and humans that were able to enter bacteria, specifically regulate bacterial gene transcripts and affect bacterial growth thereby regulating the gut microbiome.
