Interleukin-37 (IL-37) possesses the function of down-regulate systemic and local
inflammation. It is unknown whether IL-37 is expressed in human regulatory T
cells (Tregs) and its role in modulating the immune response of Tregs. In the
present study, cell surface molecules and secretory cytokines were analyzed in
order to determine the function of IL-37 in regulating inhibitory effect of human
CD4(+)CD25(+)Tregs. Meanwhile, the effects of IL-37 on T cell differentiation and
proliferation as co-culture of CD4(+)CD25(+)Treg/CD4(+)CD25(-)T cell were also
investigated. It was showed that IL-37 was expressed in cytoplasm of
CD4(+)CD25(+)Tregs, and the levels of IL-37 were gradually elevated with the
enhanced activity of CD4(+)CD25(+)Tregs. Secretory cytokines such as transforming
growth factor (TGF)-? and interleukin (IL)-10, and expressions of cell surface
molecules, including forkhead/winged helix transcription factor p3 (FOXP3) and
cytotoxic T-lymphocyte associated antigen (CTLA)-4, were significantly decreased
when IL-37 gene was silenced by siRNA. Furthermore, down-regulation of IL-37
expression in human CD4(+)CD25(+)Tregs obviously promoted proliferation of
co-cultured T cell and differentiation, together with observably enhancement of
IL-2 formation. These results demonstrated that IL-37 might manifest as a
critical protein involving in immunosuppression of human CD4(+)CD25(+)Tregs.
