The human skin microbiota could promote wound healing

Skin commensals are crucial in the maintenance of the epithelial barrier function, regulation of the host immune system, and prevent invasion of other pathogenic microbes.        In this article, published in September 2018, Burmeister et al show that Staphlylococcus, Streptococcus, Pseudomonas, Corynebacterium, and anaerobes have both beneficial and harmful effects depending Read more…

Could skin microbiota reduce cancer risk?

Researchers from the Department of Dermatology of the University of California have a commensal strain of Staphylococcus epidermidis that protects against skin neoplasia. This strain produces 6-N-hydroxyaminopurine (6-HAP), a molecule that inhibits DNA polymerase activity. Mice colonized with this strain have a reduced incidence of ultraviolet-induced tumors compared to control mice (colonized with Read more…
