To verify the hypothesis that inflammatory cytokines IL37b were mainly derived from monocytes, explore the correlation of IL37b with IL-6, IL-17A, IFN-α, IL-1β, IL-10, and TNF-α, in our study, we collected blood samples from 53 cases of dengue fever from The Eighth People's Hospital of Dongguan City and 20 healthy volunteers’ blood were used as controls. Here, IL17A is linked to dengue disease.
