BACKGROUND: We have previously shown that curcumin exhibited an outstanding anti-HCMV effect in vitro and in vivo. However, the underlying mechanism for the anti-HCMV effect remains unclear.

METHODS: Levels of IL-6 and TNF-α cytokine secretions in HELF cells were determined by enzyme-linked immunosorbent assay (ELISA); cell cycles were assessed by flow cytometry; ie and ul83 gene expressions were evaluated using reverse transcriptase real-time quantitative PCR; HCMV IE and UL83 antigen expressions were studied usingimmunofluorescence staining assay and western blot.

RESULTS: Curcumin reduced HCMV immediate early antigen (IEA) and UL83A expressions and IL-6, and TNF-α secretions and recovered cell proliferation to normal level in HCMV infected HELF cells.

CONCLUSIONS: Curcumin anti-HCMV effect may possibly be that curcumin concurrently alters host cell microenviroment and inhibits the HCMV antigen expressions. These findings may provide a basic understanding of the curcumin anti-HCMV effect and a novel strategy for further development of curcumin anti-HCMV treatment.
