This cross talk between stress perception, which involves the brain, and the skin is mediated through the “brain-skin connection”.
Study leader Petra Arck hypothesized that stress could exacerbate skin disease by increasing the number of immune cells in the skin.
The researcher said that the team exposed mice to sound stress, and found that the stress challenge resulted in higher numbers of mature white blood cells in the skin.
Based on their observations, the researchers came to the conclusion that stress activates immune cells, which in turn are central in initiating and perpetuating skin diseases. The study by Arck appears in the November issue of The American Journal of Pathology.
