1/11 Ever wondered why men have more S. aureus infections than women? Check out how testosterone stimulates S. aureus through activation of quorum sensing in our @harristryonlab preprint. Led by M. Sindhura John PhD @UTSWDerm. A #microbiome #staph#mrsa🧵

www.biorxiv.org Androgens at the skin surface regulate S. aureus pathogenesis through the activation of agr quorum... Staphylococcus aureus, the most frequent cause of skin infections, is more common in men than women and selectively colonizes the skin during inflammation. Yet, the specific cues that drive infection...

Honored to share our work @SocInvestDerm 2026, on the skin, and how the immune system, the endocrine system, and the skin microbes interface. Our latest is now in press published with @natureportfolio.nature.com Nature Microbiology! #research. rdcu.be/e50PE

Society for Investigative Dermatology @SocInvestDerm Mar 6

Tamia Harris-Tryon, MD/PhD (UT Southwestern) presents on immune-endocrine regulation of the skin microbiome.

Her lab investigates how resident microbes shape the skin barrier + contribute to inflammatory disease.

See Thursday's schedule: sidnet.org/annualmeeting/…

Exciting to have our findings out after peer review!!! The skin generates sex steroids in nanomolar to micromolar amounts, depending on the sex steroid and the skin site. Specifically skin androgens regulate S. aureus quorum sensing.
