BACKGROUND: Influenza A viruses (IAV) result in severe public health problems
with worldwide each year. Overresponse of immune system to IAV infection leads to
complications, and ultimately causing morbidity and mortality. OBJECTIVE:
Curcumin has been reported to have anti-inflammatory ability. However, its
molecular mechanism in immune responses remains unclear. METHODS: We detected the
pro-inflammatory cytokine secretion and nuclear factor kappa-light-chain-enhancer
of activated B cell (NF-?B)-related protein expression in human macrophages or
mice infected by IAV with or without curcumin treatment. RESULTS: We found that
the IAV infection caused a dramatic enhancement of pro-inflammatory cytokine
productions of human macrophages and mice immune cells. However, curcumin
treatment after IAV infection downregulated these cytokines production in a
dose-dependent manner. Moreover, the NF-?B has been activated in human
macrophages after IAV infection, while administration of curcumin inhibited NF-?B
signaling pathway via promoting the expression of nuclear factor of kappa light
polypeptide gene enhancer in B-cells inhibitor, alpha (I?B?), and inhibiting the
translocation of p65 from cytoplasm to nucleus. CONCLUSIONS: In summary, IAV
infection could result in the inflammatory responses of immune cells, especially
macrophages. Curcumin has the therapeutic potentials to relieve these
inflammatory responses through inhibiting the NF-?B signaling pathway.
