Mouse spleen expression profile after systemic Candida glabrata infection

ABSTRACT: Pleiotropic type I interferons (IFNs-I) fulfil multiple protective functions during infectious diseases, but can also exert detrimental effects for the host leading to immunopathology. Here, we report that IFNs-I promote the dysregulation of Fe homeostasis in macrophage populations and in the spleen during systemic infections with the intracellular pathogen Candida glabrata, leading to fungal survival and persistence. By using microarray expression profiling with RNA isolated from mouse spleens upon systemic Candida glabrata infection and subsequent in vitro interaction experiments we show that IFN-I signaling induces global transcriptional downregulation of key players in Fe homeostasis and profoundly alters Fe transport mechanisms within macrophages.

Response of Candida glabrata to low pH

Project description:To examine the role of a glycosylphosphatidylinositol-linked aspartyl protease, CgYps1, in the regulation of pH homeostasis in Candida glabrata, transcriptional profiling analysis was carried out on wild-type and Cgyps1∆ cells grown in YNB medium (pH 5.5) and in YNB medium adjusted to pH 2.0. Genes involved in carbohydrate and amino acid metabolism, protein folding and stress response pathways were found to be differentially regulated in response to acidic environment in both the strains.

Limosilactobacillus fermentum Limits Candida glabrata Growth by Ergosterol Depletion

Project description:Candida glabrata is a human-associated opportunistic fungal pathogen. It shares its niche with Lactobacillus spp. in the gastrointestinal and vaginal tract. In fact, Lactobacillus species are thought to competitively prevent Candida overgrowth. We investigated the molecular aspects of this antifungal effect by analyzing the interaction of C. glabrata strains with Limosilactobacillus fermentum. From a collection of clinical C. glabrata isolates, we identified strains with different sensitivities to L. fermentum in coculture. We analyzed the variation of their expression pattern to isolate the specific response to L. fermentum. C. glabrata-L. fermentum coculture induced genes associated with ergosterol biosynthesis, weak acid stress, and drug/chemical stress. L. fermentum coculture depleted C. glabrata ergosterol. The reduction of ergosterol was dependent on the Lactobacillus species, even in coculture with different Candida species. We found a similar ergosterol-depleting effect with other lactobacillus strains (Lactobacillus crispatus and Lactobacillus rhamosus) on Candida albicans, Candida tropicalis, and Candida krusei. The addition of ergosterol improved C. glabrata growth in the coculture. Blocking ergosterol synthesis with fluconazole increased the susceptibility against L. fermentum, which was again mitigated by the addition of ergosterol. In accordance, a C. glabrata Derg11 mutant, defective in ergosterol biosynthesis, was highly sensitive to L. fermentum. In conclusion, our analysis indicates an unexpected direct function of ergosterol for C. glabrata proliferation in coculture with L. fermentum.

Copper acts synergistically with fluconazole in Candida glabrata by compromising drug efflux, zinc homeostasis and sterol metabolism

Project description:In this study we used a transcriptomic approach to study the molecular determinants of the synergy between copper and fluconazole, in Candida glabrata, the second most frequent cause of invasive candidiasis. We demonstrate that copper acts together with fluconazole by downregulating three distinct pathways: azole efflux, ergosterol biosynthesis and zinc homeostasis. Coincidently, all these pathways are important for C. glabrata to cope with fluconazole stress. Therefore, when copper and fluconazole are combined cells fail to detoxify this drug and accumulate toxic methylated intermediates of sterol metabolism. This accumulation, possibly together with copper-induced lipid damages, should affect the activity of plasma membrane transporters, which impedes zinc uptake, leading to zinc depletion
