How do yeast sense mitochondrial dysfunction?
Dmitry A. Knorre1, Svyatoslav S. Sokolov1, Anna N. Zyrina2, Fedor F. Severin1,3
Apart from energy transformation, mitochondria play important signaling roles. In yeast, mitochondrial signaling relies on several molecular cascades. However, it is not clear how a cell detects a particular mitochondrial malfunction. In our review we argue that in yeast the major known routes of mitochondrial signaling are moderated by non-mitochondrial inputs.
Chlamydia trachomatis Genital Infections
Catherine M. O’Connell and Morgan E. Ferone
Chlamydia trachomatis infections are the most commonly reported sexually transmitted bacterial infections in the US and globally. Ascending infection may result in infertility, ectopic pregnancy and chronic pelvic pain in some women. In this review we provide an overview of current knowledge regarding epidemiology, disease outcomes and effective treatment of chlamydial genital tract infection and explore potential mechanisms facilitating C. trachomatis infection of genital mucosa identified via bioinformatics and other molecular approaches.
Hepatitis B virus and its sexually transmitted infection – an update
Takako Inoue1 and Yasuhito Tanaka1,2
About 5% of the world’s population has chronic hepatitis B virus (HBV) infection, and nearly 25% of carriers develop chronic hepatitis, cirrhosis, and hepatocellular carcinoma. The purpose of this article is to provide up-to-date information on HBV and HBV infection as a major sexually transmitted infection.
Gonorrhea – an evolving disease of the new millennium
Stuart A. Hill, Thao L. Masters and Jenny Wachter
Neisseria gonorrhoeae (the gonococcus) is a Gram-negative diplococcus, an obligate human pathogen, and the etiologic agent of the sexually transmitted disease, gonorrhea. This review provides insight into the molecular epidemiology, virulence mechanisms, pathogenesis and therapeutic options.
Cryptococcus flips its lid – membrane phospholipid asymmetry modulates antifungal drug resistance and virulence
Erika Shor1, Yina Wang1, David S. Perlin1,2, and Chaoyang Xue1,2
This article comments on work published by Huang et al. (MBio, 2016), which reported that in the pathogenic fungus Cryptococcus neoformans loss of lipid flippase activity sensitized cryptococcal cells to multiple classes of antifungal drugs and abolished fungal virulence in murine models.
A novel component of the mitochondrial genome segregation machinery in trypanosomes
Anneliese Hoffmann1,2, Martin Jakob1, and Torsten Ochsenreiter1
This article comments on work published by Trikin et al. (PLoS Pathog, 2016), which described a new component of the mitochondrial genome segregation machinery in the protozoan parasite Trypanosoma brucei.
Bacterial genotoxin functions as immune-modulator and promotes host survival
R. Guidi1, L. Del Bell Belluz2, T. Frisan2
This article comments on work published by Del Bel Belluz et al. (PLoS Pathog, 2016), which demonstrated that the typhoid toxin of Salmonella enterica serovar Typhi esembles an immune-modulatory molecule rather than a toxic agent.
Genome-wide studies of telomere biology in budding yeast
March 1, 2014
In the last decade, technical advances have allowed carrying out systematic genome-wide screens for mutants affecting various aspects of telomere biology. In this review we summarize these efforts, and the insights that this Systems Biology approach has produced so far.
