Skin bacteria regulate the immune response
Reblogged from Inspiring Science:
The skin is one of our body's first lines of defense, but it's also home to a rich community of microbes -- the skin microbiome. These bacteria are important in protecting us from pathogens; changes in the skin microbiome are linked with conditions ranging from dermatitis to psoriasis. In a paper published this month in the journal PNAS, a team of scientists from the University of Pennsylvania showed that these bacteria don't just live on our skin, but also play a role in regulating our immune response.
