IL13 and allergic bronchopulmonary aspergillosis: By measuring cytokines, this study confirmed that this subgroup not only exhibited elevated levels of inflammatory cytokines, such as IL-6, but also presented a profile indicative of type 2 inflammation, including eosinophilia, and increased levels of IL-4 and IL-13, suggesting the presence of type 2 inflammation similar to that observed in ABPA.
