research Optimization of a Murine Infection Model With Trichophyton Mentagrophytes for Studying the Pathogenesis of Dermatophytosis
This study optimized a murine infection model using the Trichophyton mentagrophytes TIMM 2789 strain, specific to rodents, to study dermatophytosis pathogenesis. The model successfully mimicked natural infections, showing symptoms like hair follicle invasion. Host responses involved Th1, Th2, and Th17 cytokines, while the fungal SIDC gene highlighted the role of iron acquisition. Although SUB6 was not necessary for virulence, SUB5 overexpression suggested a compensatory mechanism. The study emphasizes the importance of selecting appropriate dermatophyte strains for experimental models.
