Protective effects of ziprasidone on the damage of hippocampal-derived neural stem cell induced by lipopolysaccharide / 中华行为医学与脑科学杂志

ABSTRACT

Objective To investigate the effects of ziprasidone on the hippocampal-derived neural stem cells (NSCs) viability and apoptosis injured.by LPS.Methods The NSCs were derived from the hippocampus of fetal rats,after the primary neurospheres passaged,the cells were treated with LPS (200 μg/L) and different concentrations of ziprasidone for 48 h or 72 h.The cell viability and the level of LDH were measured by the kit of WST-8 and LDH detected kit,respectively.Furthermore,the apoptosis rate of each dosage group was measured by using Annexin-V-FLUOS Staining Kit.Results (1) Cell viability test showed that the cell viability of LPS group (OD value,0.265± 0.047) was significantly reduced than that of sham (OD value,0.380± 0.029),LPS + 5 μM (OD value,0.316±0.008) and LPS+10 μM (OD value,0.321±0.006) group after ziprasidone treatment for 48 h.There were also significant difference of cell viability between sham,LPS+5 μM,LPS+ 10 μM and LPS group after ziprasidone treatment for 72 h.(2) LDH test showed that the LDH level of LPS group was significantly decreased than that of sham,LPS+5 μM and LPS+10 μM after 48 hour's ziprasidone treatment (P＜0.01).The LDH level of LPS group was also significantly reduced than that of sham,LPS+5 μM and LPS+10 μM after 72 hour's ziprasidone treatment (P＜ 0.01).(3) The apoptosis of LPS + 10 μM ((17.87 ± 2.29) ％),LPS + 5 μM ((18.45 ± 3.84) ％) treated group or sham group ((9.15 ± 1.54) ％) was significantly lower than LPS group ((22.67 ± 2.15)％) by using flow cytometry after 48 h treatment.Furthermore,the apoptosis of LPS+ 10 μM ((10.52± 1.42)％) treated group or sham group((8.45±1.04)％) was significantly lower than LPS group((15.70± 2.97) ％) after 72 h treatment.Conclusion The cellular damage of NSCs injured by LPS can be restrained by ziprasidone,and this effect might be one of the cellular mechanism of neural protective effect of ziprasidone.
