We show here that, contrary to the situation in T cells, FK506 activates transcription factor NF-κB in non-lymphoid cells such as fibroblasts and renal mesangial cells. We further show that FK506 induces NF-κB-regulated IL-6 production in vitro and in vivo, in particular in kidney. IL-6 has been shown previously to produce renal abnormalities in vivo, such as mesangioproliferative glomerulonephritis. Similar renal abnormalities were also observed in FK506-treated animals. These results thus suggest a causal relationship between FK506-induced NF-κB activation/IL-6 production and some of FK506-induced renal abnormalities., 金沢大学がん研究所がん分子細胞制御}, pages = {2433--2439}, title = {Immunosuppressant FK506 induces interleukin-6 production through the activation of transcription factor nuclear factor (NF)-κB implications for FK506 nephropathy}, volume = {97}, year = {1996} }
