Protective effects of Lingguizhugan decoction on amyloid-beta peptide (25–35)-induced cell injury Anti-inflammatory effects

In the present study, a human neuroblastoma cell line (SH-SY5Y) and BV-2 microglia were treated with amyloid-β peptide (25–35), as a model of Alzheimer’s disease, to evaluate the protective effects of 10-3–10-8 g/mL Lingguizhugan decoction and to examine the underlying anti-inflammatory mechanism. Lingguizhugan decoction significantly enhanced the viability of SH-SY5Y cells with amyloid-β peptide-induced injury, and lowered levels of interleukin-1β, interleukin-6, tumor necrosis factor-α and nitric oxide in the culture supernatant of activated BV-2 microglia. The effects of 10-3 g/mL Lingguizhugan decoction were more significant. These results suggest that Lingguizhugan decoction can protect SH-SY5Y cells against amyloid-β peptide (25–35)-induced injury in a dose-dependent manner by inhibiting overexpression of inflammatory factors by activated microglia.
