Immunology of dermatophytosis. Experimental study

Area of Science:

• Mycology and Immunology
• Dermatophyte Infections
• Cellular Immunity

Background:

• Dermatophytosis, a fungal infection of the skin, hair, and nails, is caused by various dermatophyte species.
• Understanding the host's cellular immune response is crucial for developing effective treatments and vaccines against dermatophytosis.
• Previous research has explored immune responses, but specific antigenic triggers require further elucidation.

Purpose of the Study:

• To investigate the cellular immunity status during experimental dermatophytosis in rabbits.
• To identify specific antigens responsible for sensitization in dermatophyte infections.
• To evaluate the role of 'Keratinase' antigenic compounds in the immune response.

Main Methods:

• Experimental dermatophytosis was induced in rabbits using Trichophyton mentagrophytes var. granulosum and Trichophyton rubrum.
• Cellular immunity was assessed using the leukocyte migration test (L.M.T.).
• The L.M.T. was performed in the presence of specific antigenic compounds, including 'Keratinase'.

Main Results:

• The study successfully established experimental dermatophytosis in rabbits.
• The leukocyte migration test indicated a cellular immune response during the infection.
• Specific antigenic compounds, particularly 'Keratinase', were implicated in the sensitization process.

Conclusions:

• Rabbits exhibit a detectable cellular immune response to experimental dermatophytosis.
• 'Keratinase' and related antigenic compounds play a significant role in sensitizing the host's immune system.
• These findings contribute to understanding dermatophyte immunology and may inform future therapeutic strategies.
