ABSTRACT
AIM:
To explore the role of calcineurin i n th e expression of NF-?B and the neurotoxicity in cultured cortical neurons treate d with interleukin-1? (IL-1?) and NMDA.METHODS:
The cultured rat cortical neurons were used in the expe riment, damage of neurons was induced by interleukin-1?(IL-1?) or excitator y amino acid (NMDA). The degree of neuron damage was examined with the methods o f MTT assay and LDH releasing rate assay, as well as the Annexin V and PI immuno fluorescence. The expression of NF-?B p65 on the neurons was tested by the West ern blot analysis.RESULTS:
Viability of neurons was obviously lower in the IL-1? group and NMDA group respectively than that in control group (P0.05). Annexin V and PI immunofluoresc ence showed that IL-1? mainly induced the neuron apoptosis, and NMDA induced th e neuron necrosis.CONCLUSIONS:
The calcineurin mediates the higher expression of N F -?B p65 and neuron damage induced by IL-1?, but not play a critical role in th e necrosis induced by NMDA in the cultured cortical neurons. These results indic ate that calcineurin is the key molecule in the apoptotic signaling pathway.
