Therefore, we evaluated the transcription of genes related to different T response profiles (Th2: IL-4, IL-13 and Il-5; Th17: IL17, IL-6 and TGF-β; Th1: IFN-γ, TNF-α, IL-6 and IL-12; Treg: IL-10 and TGF-β) in co-cultures of splenocytes with BMDCs that were previously stimulated with HF from E. granulosus. The gene discussed is IL6; the disease is hydrops fetalis.
