Clara Jundt and her team at Janssen R&D, in collaboration with Altis and UNC-Chapel Hill, conducted a study using human primary intestinal epithelial cells from multiple donors. Their aim was to determine if these cells could mimic a similar response and capture the genetic variability found in humans. The researchers treated the models with TNFα and IFNγ, revealing consistent responses across different donors. Additionally, they discovered that the JAK-STAT inhibitor tofactinib effectively blocked these responses in a dose-dependent manner.
