(Submitter supplied) The emergence of Candida auris poses a significant health challenge that has led to a new era of multidrug-resistant fungal infections. Invasive infections caused by C. auris are usually associated with remarkable morbidity and mortality. For many years, amphotericin B (AmB) remained the most efficient and the last line of treatment against most hard-to-treat fungal infections. However, strains of C. more...

(Submitter supplied) Fungal pathogens are underappreciated causes of significant morbidity and mortality worldwide. In previous studies we determined that a heat-killed, Cryptococcus neoformans fbp1-deficient strain (HK-fbp1) is a potent vaccine candidate. We determined that vaccination with HK-fbp1 confers protective immunity against lethal Cryptococcosis in an interferon γ (IFNγ)-dependent manner. In this study, we set out to uncover cellular sources and relevant targets of the protective effects of IFNγ in response to the HK-fbp1 vaccine. more...

(Submitter supplied) Cryptococcus neoformans is a ubiquitous free-living soil yeast and opportunistic pathogen that causes ~223,100 cases of cryptococcal meningitis per year, killing over 180,000 people. The pathogenicity of C. neoformans relies on its adaptation to the host conditions. An important difference between its natural environment and the mammalian host is the concentration of CO2. CO2 levels in the host fluctuate around 5%, which is ~125-fold higher than in ambient air. more...

(Submitter supplied) Cryptococcus neoformans (Cn) is an opportunistic fungal microorganism that causes life-threatening meningoencephalitis. Calorie restriction is an intervention that extends the lifespan of Cn. The mating types of Cn have striking differences in prevalence in both environmental and clinical settings. This is hypothesized to be due to differences in stress responses between mating types. Using RNAseq, we investigated how the two mating types respond to the stress of starvation during calorie restriction.

(Submitter supplied) Proper mitochondrial function is critical for the ability of the fungal pathogen Cryptococcus neoformans to cause disease. Mitochondrial dysfunction of WT cells treated with antimycin A or L-DOPA, or on cells lacking Cir1 is evident from this dataset. These experiments revealed influences on transcript levels of genes encoding Fe-S cluster assembly components and the response to oxidative stress in Cryptococcus neoformans.

(Submitter supplied) Elevation of arginase enzyme activity in the lung contributes to the pathogenesis of various chronic inflammatory diseases and infections. Inhibition of arginase expression and activity is able to alleviate those effects. Here, we investigated the immunomodulatory effect of arginase inhibitor in C. neoformans infection. In the pulmonary cryptococcosis model that was shown to recapitulate human infection, we found arginase expression was excessively induced in the lung during the late stage of infection. more...

(Submitter supplied) Candida auris has emerged as a problematic fungal pathogen associated with high morbidity and mortality. Amphotericin B (AmB) is the most effective antifungal used to treat invasive fungal candidiasis, with resistance rarely observed among clinical isolates. However, C. auris possesses extraordinary resistant profiles against all available antifungal drugs, including AmB. In our pursuit of potential solutions, we conducted a screening of a panel of 727 FDA-approved drugs and identified the proton pump inhibitor lansoprazole (LNP) as a potent enhancer of AmB’s activity against C. more...

(Submitter supplied) Cryptococcus neoformans (Cn) is an opportunistic fungal microorganism that causes life-threatening meningoencephalitis. During the infection, the microbial population is heterogeneously composed of cells with varying generational ages, with older cells accumulating during chronic infections. This is attributed to their enhanced resistance to phagocytic killing and tolerance of antifungals like fluconazole (FLC). more...

(Submitter supplied) Bacterial persisters, a subpopulation of genetically susceptible cells that are normally dormant and tolerant to bactericides, have been studied extensively because of their clinical importance. In comparison, much less is known about the determinants underlying fungicide-tolerant fungal persister formation in vivo. Here, we report that during mouse lung infection, Cryptococcus neoformans forms persisters that are highly tolerant to amphotericin B (AmB), the standard of care for treating cryptococcosis. more...

(Submitter supplied) To investigate the pleiotropic roles of Lkh1 in stress response and virulence, we constructed lkh1∆ mutant strains. In this study, we found that Tor1 was an upstream regulator of Lkh1 in C. neoformans. We then performed gene expression profiling analysis to elucidate signaling circuitry downstream of CnLkh1 in the TOR1-Lkh1 pathway using data obtained from RNA seq of 2 different strains (WT of lkh1∆ mutant) with or without rapamycin treatment.

(Submitter supplied) Casein kinase 2 (CK2) is a potential therapeutic target for several human diseases due to its crucial roles in growth, differentiation, and metabolic homeostasis. This study delves into the role of the CK2 complex in Cryptococcus neoformans, a key fungal pathogen causing meningitis. In C. neoformans, the CK2 complex is made up of a main catalytic subunit (Cka1) and two regulatory subunits (Ckb1 and Ckb2). more...

(Submitter supplied) Among the causative agents of neonatal diarrhea in calves, two of the most prevalent are bovine coronavirus (BCoV) and Cryptosporidium parvum. Although several studies indicate that co-infections between the two pathogens are associated with greater symptom severity, the host-pathogen interplay remains to be further investigated. The main objective of the present work was to investigate the modulation of the transcriptome of HCT-8 cells during single or co-exposures to BCoV and C. more...

(Submitter supplied) Macrophages play a pivotal role in determining the fate of invading Cryptococcus neoformans cells, and this outcome is highly dependent on how the pathogen modulates phagocyte activation and function. A common consequence of the C. neoformans-host interaction is the establishment of a latent infection, in which the yeast enters a dormant state. In this study, we investigated whether dormant cells could modulate murine bone marrow-derived macrophages (BMDMs) differently from non-dormant cells, thereby providing mechanistic insights into latent infection. more...

(Submitter supplied) In bacteria, antibiotic tolerance, the ability of a susceptible population to survive high doses of cidal drugs, has been shown to compromise therapeutic outcomes. In comparison, whether fungicide tolerance can be induced by host-derived factors during fungal diseases remains unproven. Here, through a systematic evaluation of metabolite-drug-fungal interactions in the leading fungal meningitis pathogen, Cryptococcus neoformans, we found that glucose, on which the brain depends for fuel, induces fungal tolerance to amphotericin B (AmB) in mouse brain tissue and patient cerebrospinal fluid via the fungal glucose repression activator Mig1. more...

(Submitter supplied) Cryptococcus spp. are environmental fungi that first must adapt to the host environment before they can cause life-threatening meningitis in immunocompromised patients. Host CO2 concentrations are 100-fold higher than the external environment and strains unable to grow at host CO2 concentrations are not pathogenic. Using a genetic screening and transcriptional profiling approach, we found that the TOR pathway is critical for C. more...
