Abstract

Aim: To investigate the effect of fractalkine on the expression of the tumor necrosis factor-α(TNF-α), interleukin-1β (IL-1β), and nitric oxide (NO) in LPS-activated murine microglia cells line N9.

Methods: In vitro LPS-activated microglia cells were treated for 24 h in the presence of fractalkine. The level of TNF-α and IL-1β in the culture supernatants were measured by enzyme-linked immunosorbent assay (ELISA), The level of NO in the culture supernatants were quantitated by the NO test assay.

Results: The concentration of TNF-α, IL-1β and NO in the culture supernatants evidently increased in LPS-activated microglia cells groups and prominently decreased by the fractalkine co-incubated.

Conclusion: It is thus concluded that fractalkine has neuroprotective functions by inhibiting the expression of inflammatory factor in activated microglia cells.
