Evolving approaches to profiling the microbiome in skin disease

Area of Science:

• Microbiology
• Immunology
• Dermatology

Background:

• Human skin hosts a complex microbiome of bacteria, fungi, viruses, and mites.
• Microbial communities reside on the skin surface, in deeper layers, and within appendages like hair follicles and sweat glands.
• Imbalances in the skin microbiome (dysbiosis) are associated with inflammatory skin conditions such as atopic dermatitis, acne, and psoriasis.

Purpose of the Study:

• To review current and emerging methods for profiling the skin microbiome.
• To highlight the importance of understanding microbial interactions in skin health and disease.
• To discuss the potential of advanced technologies for detailed skin microbiome analysis.

Main Methods:

• Review of existing literature on skin microbiome research.
• Discussion of traditional methods like 16S rRNA gene sequencing.
• Emphasis on advanced techniques including metagenomics and functional 'omic' approaches.

Main Results:

• Traditional methods like 16S rRNA sequencing have limitations in species/strain resolution.
• Metagenomics and other functional 'omic' approaches offer comprehensive insights into the skin microbiome.
• Inter-species and multi-kingdom interactions are crucial but understudied drivers of dysbiosis.

Conclusions:

• Advanced profiling technologies are essential for a deeper understanding of the skin microbiome in disease.
• Meta-omic studies combined with experimental and clinical validation are needed to confirm functional roles.
• Evolving skin microbiome profiling methods are key to advancing research in dermatology and related fields.
