Abstract:
Objective:To evaluate the effect of berberine (BBR) on morphine-induced activation of BV2 microglial cells.Methods:The BV2 microglial cells were divided into 3 groups ( n=12 each) using a random number table method: control group (C group), morphine group (Mor group)and morphine+ BBR group (Mor+ BBR group). The Mor group was treated for 24 h with a final concentration of 200 μmol/L morphine, while C group was treated for 24 h with an equal volume of PBS buffer. Mor+ BBR group was first treated for 2 h with a final concentration of 20 μmol/L berberine, followed by treatment with a final concentration of 200 μmol/L morphine for another 24 h. The viability of BV2 microglial cells was determined using the CCK-8 assay, the concentrations of interleukin-1beta (IL-1β), tumor necrosis factor-alpha (TNF-α) and IL-10 in supernatant were measured using enzyme-linked immunosorbent assay, and the expression of CD86 and NF-κB proteins in microglial cells was detected using Western blot. Results:Compared with group C, the BV2 microglial cell viability and concentrations of IL-1β and TNF-α were significantly increased, the concentrations of IL-10 were decreased, and the expression of CD86 and NF-κB in microglial cells was up-regulated in Mor group ( P<0.05). Compared with Mor group, the BV2 microglial cell viability and concentrations of IL-1β and TNF-α were significantly decreased, the concentrations of IL-10 were increased, and the expression of CD86 and NF-κB in microglial cells was down-regulated in Mor+ BBR group( P<0.05). Conclusions:BBR can inhibit morphine-induced activation of BV2 microglial cells.
