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.
Depletion of SNAP-23 and Syntaxin 4 alters lipid droplet homeostasis during Chlamydia infection
December 3, 2019
This study reveals that the plasma membrane SNARE proteins SNAP-23 and Syntaxin 4 are crucial for Chlamydia trachomatis development by regulating lipid droplet homeostasis and supporting the formation of infectious progeny within host cells.
The role of Lactobacillus species in the control of Candida via biotrophic interactions
November 25, 2019
Microbial communities, including Candida and Lactobacillus species, play a crucial role in human health, particularly in the context of mucosal infections, but our understanding of their interactions and effects is still incomplete due to the variability of species and isolates as well as the complexity of the human host.
Sulfur dioxide resistance in Saccharomyces cerevisiae: beyond SSU1
November 21, 2019
This article discusses the importance of understanding sulfite resistance in Saccharomyces cerevisiae due to its use in winemaking and the potential role of the transcription factor Com2. While the SSU1 gene and its activity have been correlated with sulfite tolerance, the work by Lage et al. (2019) indicates that Com2 might control a large percentage of the genes activated by SO2 and contribute to the yeast's protective response, offering new insights into the molecular factors influencing this oenological trait.
Yeast can express and assemble bacterial secretins in the mitochondrial outer membrane
November 19, 2019
Secretins, essential components of bacterial secretion systems, can be expressed in yeast and show differential dependencies on mitochondrial import and assembly factors for membrane integration, suggesting diverse pathways for their assembly into the bacterial outer membrane.
Metabolic reprogramming of Salmonella infected macrophages and its modulation by iron availability and the mTOR pathway
November 14, 2019
This article shows that iron plays a critical role in both the immune response and metabolic reprogramming of macrophages during infection, influencing the TCA cycle and mTOR pathway, with implications for the growth of intracellular bacteria like Salmonella.
Tribal warfare: Commensal Neisseria kill pathogen Neisseria gonorrhoeae using its DNA
October 19, 2019
This article comments on work published by Kim et al (Cell Host Microbe, 2019), which adds a new dimension to the concept of commensal protection. It shows that commensal Neisseria kill the closely related pathogen N. gonorrhoeae through an unexpected mechanism, one that involves genetic competence, DNA methylation state and recombination.
Viral attenuation by Endonuclease G during yeast gametogenesis: insights into ancestral roles of programmed cell death?
December 17, 2019
This article relates to the study "Meiotic viral attenuation through an ancestral apoptotic pathway" by Gao et al. (Proc Natl Acad Sci, 2019), which shows that programmed cell death may have evolved as a viral defence mechanism, as demonstrated by yeast studies showing that the mitochondrial nuclease Nuc1 translocates to the cytosol during meiosis to attenuate dsRNA viruses, linking viral control to meiotic cell death processes.
