Project description:Although dermatophytes are the most common agents of superficial mycoses in humans and animals, the molecular basis of the pathogenicity of these fungi is largely unknown. In vitro digestion of keratin by dermatophytes is associated with the secretion of multiple proteases, which are assumed to be responsible for their particular specialization to colonize and degrade keratinized host structures during infection. To address this hypothesis a guinea pig infection model was established for the zoophilic dermatophyte Arthroderma benhamiae which causes highly inflammatory cutaneous infections in humans and rodents. Microarray analysis revealed a distinct in vivo protease gene expression profile in the fungal cells, which is surprisingly different from the pattern elicited during in vitro growth on keratin. Instead of the major in vitro expressed proteases others were activated specifically during infection. These enzymes are therefore suggested to fulfill important functions that are not exclusively associated with the degradation of keratin. As the most upregulated in vivo specific A. benhamiae sequence we discovered the gene encoding the serine protease subtilisin 6, which is a known major allergen in the related dermatophyte Trichophyton rubrum and putatively linked to host inflammation. In addition, our approach identified other candidate pathogenicity related factors in A. benhamiae, such as genes encoding key enzymes of the glyoxylate cycle and an opsin-related protein. This first broad transcriptional profiling approach during dermatophyte infection gives new molecular insights into pathogenicity associated mechanisms that make these microorganisms the most successful etiologic agents of superficial mycoses. Keywords: Two-condition experiment, strong proteolytic activity in the supernatant versus no proteolytic activity or infected tissue versus no proteolytic activity

Keywords: Two-condition experiment, strong proteolytic activity in the supernatant versus no proteolytic activity or infected tissue versus no proteolytic activity Three independently prepared A. benhamiae replicates grown in each of the three media, Sabouraud, soy and keratin-soy medium (designated SabA/B/C, soyA/B/C and keratin-soyA/B/C) were used. ARN from skin samples and fungus together of Guinea Pig infected with A. benhamieae were prepared. Pairwise transcriptional comparisons, i.e. soy versus Sabouraud, keratin-soy versus Sabouraud and Guinea Pig infected versus Sabouraud were done. The total number of slides in this study was 18.

Project description:We report the application of dual RNA-sequencing technology for high-throughput profiling of histone modifications in HaCat cells and Trichophyton mentagrophytes complex.For co-culture assays, a ratio of 2.5×105 cells/mL of keratinocytes to 2.5×105 conidia/mL of T. mentagrophytes, T. interdigitale, and T. tonsurans solution were used (MOI=1). The experiment was carried out for 24 h in a humidified incubator maintained at 37 ºC . We used dual RNA-seq to study the different host immune responses against the T. mentagrophytes complex and we the transcriptional profiles of differentially expressed genes in dermatophytes.

Project description:Under the action of Trichophyton 1000 UG / ml, the colony of Trichophyton mentagrophyte was completely inhibited. The spore number and germination rate of Trichophyton mentagrophyte under the action of 100ug / ml and 10ug / ml were significantly lower than those in the control group. Under the action of Trichophyton, the mitochondria in the mycelium of Trichophyton mentagrophyte were cleaved. Under the action of trichomycin, the related genes in mitochondria decreased significantly. This showed that mitochondria were obviously damaged during trichomycin treatment. It is speculated that Trichophyton can cause mitochondrial damage and reduce the efficiency of respiratory chain, but Trichophyton can synthesize enough ATP by regulating related ATP synthase to resist the invasive effect caused by Trichophyton stimulation.
