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. https://t.co/iG2O001i83

[Society for Investigative Dermatology @SocInvestDerm]

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.

@andrewlji Thanks Andrew!

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.

Great summary of what is known about S. aureus/skin dynamics. We are exciting to be expanding the picture with our findings demonstrating how the skin secretes hormones and how testosterone stimulates QS in S. aureus. https://t.co/aCzsdOSy20

Congrats to all on a labor of love. I recall "pd-1 is boring" as a grant review comment. Not so boring in fact...
