An international collaborative research group consisting of Professor HASEGAWA Akito and Professor ABE Riichiro of the Department of Dermatology, Niigata University Graduate School of Medical and Dental Sciences, and Professor Matthias Mann of the Max Planck Institute for Biochemistry (MPIB) in Germany, has developed a novel treatment that improves the outcome for patients with toxic epidermal necrolysis (TEN), a severe cutaneous drug reaction.
TEN is a severe adverse drug reaction; patients have very poor prognosis with a mortality rate of 30 percent. Using spatial proteomics1, a state-of-the-art research method, our research group discovered that the JAK/STAT pathway2, which causes inflammation, is deeply involved in the pathology of TEN. Seven patients with TEN were treated with a JAK inhibitors3 that inhibits this pathway, and we obtained favorable results. The research was published in Nature on October 16, 2024.
1.Spatial proteomics
Proteomics is the comprehensive analysis of protein expression in cells and tissues. Spatial proteomics is a method of analysis that combines spatial information on the location of a protein with information on the amount of protein expression from tissue sections.
2.JAK/STAT pathway
Plays a role in transmitting information about inflammation, cell proliferation, and differentiation within cells.
3.JAK inhibitor
A drug that suppresses the function of the JAK/STAT pathway by inhibiting JAK. Currently used to treat a variety of diseases, including atopic dermatitis and rheumatoid arthritis.
