Case Study: Harnessing the Gut-Skin-Brain Axis in Health & Disease

  • As crucial interface organs, the gut, brain and skin have much in common. Emerging research has shown that skin microbiota may play a critical role at the interface of all three organs. Therefore, it is not surprising that conditions affecting one organ’s microbiota may also have manifestations in the two others.
  • More importantly, a better understanding of the intestinal microflora and it’s subsequent relationship with our skin may provide new insights into developing unique product candidates that will accurately treat a spectrum of skin disease indications with current un met needs.
  • As the microbiome continues to enter the scientific mainstream, this multiple complexity organ is largely unexplored, some examples will be presented on gut-brain-skin connection in some dermatosis and how skin disorders could be involved in some neurodegenerative disorders
