The following study illustrates how transcriptomics and proteomics complement one another to clarify the pathology of a complex, and little understood disease. Atopic dermatitis (AD) is the most common chronic skin condition affecting up to 20% of children and 7-10% of adults, depending on the population. The disease is incredibly complex and heterogenous, so finding an effective treatment has proven to be quite difficult. Moreover, the use of the skin biopsy as a method of sample collection is incredibly invasive and can cause scarring. Therefore, Rojahn et al. (2020) sought to test a less invasive and painful method known as skin blistering, which, unlike skin biopsies, would allow both transcriptomic analysis from skin cells, and proteomic analysis of the interstitial fluid from the blister.
