Broad-spectrum antifungal activities and mechanism of drimane sesquiterpenoids
March 12, 2020
This study identifies (-)-drimenol as a potent broad-spectrum antifungal agent effective against multiple pathogenic fungi, including drug-resistant strains, and reveals its mechanism of action involves disruption of fungal membranes and targeting Crk1-related pathways, with potential for structural optimization to enhance efficacy.
More than flipping the lid: Cdc50 contributes to echinocandin resistance by regulating calcium homeostasis in Cryptococcus neoformans
February 20, 2020
In this article, the authors comment on the study "A mechanosensitive channel governs lipid flippase-mediated echinocandin resistance in Cryptococcus neoformans" by Cao et al. (mBio, 2019), which uncovers a dual role for the lipid flippase subunit Cdc50 in Cryptococcus neoformans, linking lipid translocation and calcium signaling via its interaction with the mechanosensitive channel Crm1, thereby contributing to innate resistance against the antifungal drug caspofungin.
Stable and destabilized GFP reporters to monitor calcineurin activity in Saccharomyces cerevisiae
February 5, 2020
This study introduces GFP-based transcriptional reporters driven by a calcineurin-dependent response element, enabling real-time monitoring of calcineurin activity in live yeast cells for studying stress responses, aging, and antifungal drug screening.
New insights in the mode of action of anti-leishmanial drugs by using chemical mutagenesis screens coupled to next-generation sequencing
January 21, 2020
In this article, the authors comment on the study "Coupling chemical mutagenesis to next generation sequencing for the identification of drug resistance mutations in Leishmania" by Bhattacharya et al. (Nat Commun, 2019), which introduces Mut-seq, a chemical mutagenesis and sequencing approach, to uncover drug resistance mechanisms in Leishmania, revealing links between lipid metabolism genes and miltefosine resistance, and a protein kinase involved in translation conferring paromomycin resistance.
Microfluidic techniques for separation of bacterial cells via taxis
January 15, 2020
Microfluidic tools, ideal for studying microbial motility due to their control over laminar flows at microscopic scales, enable precise analysis of various taxis behaviors and have advanced applications in synthetic biology, directed evolution, and medical microbiology.
Influence of delivery and feeding mode in oral fungi colonization – a systematic review
January 7, 2020
A systematic review of oral fungal colonization in infants found that while breastfeeding did not significantly affect the oral mycobiome, vaginal delivery was associated with higher oral yeast colonization, particularly of Candida albicans.
A holobiont view on thrombosis: unravelling the microbiota’s influence on arterial thrombus growth
January 6, 2020
In this article, the authors comment on the study "The microbiota promotes arterial thrombosis in low-density lipoprotein receptor-deficient mice" by Kiouptsi et al. (mBio, 2019) that showed that commensal microbiota, intricately linked to host physiology, may influence cardiovascular disease, as shown by studies using germ-free atherosclerosis-prone mice to examine how microbial presence and diet affect arterial thrombosis and lesion development.
The euchromatic histone mark H3K36me3 preserves heterochromatin through sequestration of an acetyltransferase complex in fission yeast
January 3, 2020
This study reveals that the loss of heterochromatin silencing in Set2-deficient cells is due to unrestrained Mst2C activity, highlighting the need for spatially restricted chromatin-modifying enzymes to maintain distinct chromatin states.
Raman-based sorting of microbial cells to link functions to their genes
February 10, 2020
In this article, the authors comment on the study "An automated Raman-based platform for the sorting of live cells by functional properties" by Lee et al. (Nat Microbiol, 2019), which presents a high-throughput optofluidic platform that integrates Raman microspectroscopy and microfluidics to accurately link microbial phenotypes to genotypes within complex communities, enabling efficient functional sorting and analysis of microbiome members.
