    Integrin-based diffusion barrier separates membrane domains enabling the formation of microbiostatic frustrated phagosomes

    Michelle E Maxson, Xenia Naj ... Sergio Grinstein
    The diffusional barrier formed between phagocyte integrin and fungal glucans preserves the microbiostatic phagocytic environment generated during the frustrated phagocytosis of Candida albicans hypha.

    Candida albicans exhibits heterogeneous and adaptive cytoprotective responses to antifungal compounds

    Vanessa Dumeaux, Samira Massahi ... Michael T Hallett
    Candida albicans cells respond in two distinct ways to fluconazole exposure where cells enter the Ribo-dominant state characterized by an upregulation of ribosomal-related proteins and processes, or cells enter the Stress-dominant state characterized by the upregulation of stress responses.

    Transcriptional rewiring over evolutionary timescales changes quantitative and qualitative properties of gene expression

    Chiraj K Dalal, Ignacio A Zuleta ... Alexander D Johnson
    Rewiring of transcriptional circuits can preserve a basic output yet alter almost all of the circuit's quantitative and qualitative features.

    The evolution of drug resistance in clinical isolates of Candida albicans

    Christopher B Ford, Jason M Funt ... Aviv Regev
    Loss-of-heterozygosity mutations, but not aneuploidies, are linked to the evolution of drug resistance in Candida albicans isolated from immunocompromised patients.

    Genome plasticity in Candida albicans is driven by long repeat sequences

    Robert T Todd, Tyler D Wikoff ... Anna Selmecki
    Previously uncharacterized long repeat sequences are associated with significant genome variation that can increase fitness and promote antifungal drug resistance in diverse isolates of Candida albicans.

    Expandable and reversible copy number amplification drives rapid adaptation to antifungal drugs

    Robert T Todd, Anna Selmecki
    Novel segmental chromosome amplifications in Candida albicans provide rapid adaptation to the most widely used antifungal drugs.

    Gene regulatory network plasticity predates a switch in function of a conserved transcription regulator

    Isabel Nocedal, Eugenio Mancera, Alexander D Johnson
    Rapid evolutionary rewiring of the meiosis transcription network facilitated a switch in the function of a master regulator from regulating meiosis to regulating biofilm formation.

    Diverse stimuli engage different neutrophil extracellular trap pathways

    Elaine F Kenny, Alf Herzig ... Arturo Zychlinsky
    NETs induction, a central component of the innate immune response, utilises assorted signalling pathways as demonstrated through the analysis of healthy and patient neutrophils treated with five distinct stimuli.

    The Candida albicans virulence factor candidalysin polymerizes in solution to form membrane pores and damage epithelial cells

    Charles M Russell, Katherine G Schaefer ... Francisco N Barrera
    The molecular mechanism that candidalysin uses to perforate membranes is unraveled, which opens the door to the rational design of inhibitors against candidiasis.

    Intravital imaging-based genetic screen reveals the transcriptional network governing Candida albicans filamentation during mammalian infection

    Rohan S Wakade, Laura C Ristow ... Damian J Krysan
    An intravital screen identifies the transcription factors that govern gene expression of the human fungal pathogen Candida albicans during filamentation in a mammalian host.
