On Jan. 21, 2021, scientists at the Wellcome Sanger Institute announced they had created a highly detailed map of skin, which revealed that cellular processes from development are re-activated in cells from patients with inflammatory skin disease. The researchers from the Wellcome Sanger Institute, Newcastle University and Kings College London, discovered that skin from eczema and psoriasis patients share many of the same molecular pathways as developing skin cells.

The study, published in Science, provided a completely new understanding of inflammatory disease, opening up new avenues for research on other inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease.
