Comparative Transcriptome Analysis of T. rubrum, T. mentagrophytes, and M. gypseum Dermatophyte Biofilms in Response to Photodynamic Therapy.
Dermatophyte biofilms frequently count for inadequate responses and resistance to standard antifungal treatments, resulting in refractory chronic onychomycosis infection. Although antimicrobial photodynamic therapy (aPDT) has clinically proven to exert significant antifungal effects or even capable of eradicating dermatophyte biofilms, considerably less is known about the molecular mechanisms underlying aPDT and the potential dysregulation of signaling networks that could antagonize its action. The aim of this study is to elucidate the molecular mechanisms underlining aPDT combat against dermatophyte biofilm in recalcitrant onychomycosis and to decipher the potential detoxification processes elicited by aPDT, facilitating the development of more effective photodynamic interventions. We applied genome-wide comparative transcriptome analysis to investigate how aPDT disrupting onychomycosis biofilm formed by three distinct dermatophytes, including Trichophyton rubrum, Trichophyton mentagrophytes, and Microsporum gypseum, the most frequently occurring pathogenic species. In total, 352.13 Gb of clean data were obtained for the transcriptomes of dermatophyte biofilms with or without aPDT treatment, resulting in 2,422.42 million reads with GC content of 51.84%, covering 99.9%, 98.5% and 99.4% of annotated genes of T. rubrum, T. mentagrophytes, and M. gypseum, respectively. The genome-wide orthologous analysis identified 6624 transcribed single-copy orthologous genes in all three species, and 36.5%, 6.8% and 17.9% of which were differentially expressed following aPDT treatment. Integrative orthology analysis demonstrated the upregulation of oxidoreductase activities is a highly conserved detoxification signaling alteration in response to aPDT across all investigated dermatophyte biofilms. This study provided new insights into the molecular mechanisms underneath anti-dermatophyte biofilm effects of aPDT and successfully identified a conserved detoxification regulation upon the aPDT application.
期刊介绍:
Mycopathologia is an official journal of the International Union of Microbiological Societies (IUMS). Mycopathologia was founded in 1938 with the mission to ‘diffuse the understanding of fungal diseases in man and animals among mycologists’. Many of the milestones discoveries in the field of medical mycology have been communicated through the pages of this journal. Mycopathologia covers a diverse, interdisciplinary range of topics that is unique in breadth and depth. The journal publishes peer-reviewed, original articles highlighting important developments concerning medically important fungi and fungal diseases. The journal highlights important developments in fungal systematics and taxonomy, laboratory diagnosis of fungal infections, antifungal drugs, clinical presentation and treatment, and epidemiology of fungal diseases globally. Timely opinion articles, mini-reviews, and other communications are usually invited at the discretion of the editorial board. Unique case reports highlighting unprecedented progress in the diagnosis and treatment of fungal infections, are published in every issue of the journal. MycopathologiaIMAGE is another regular feature for a brief clinical report of potential interest to a mixed audience of physicians and laboratory scientists. MycopathologiaGENOME is designed for the rapid publication of new genomes of human and animal pathogenic fungi using a checklist-based, standardized format.
