Abstract:
Objective To explore the impact of acute Toxoplasma gondii infection on cerebral proteins and nerve growth in mice by 2D electrophoresis. Methods The cerebral proteins from C57BL/6J mice infected with Toxoplasma gondii and normal paired mice were extracted. The discrepant proteins were checked by 2D electrophoresis. Isoelectric focusing was determined as the first direction (immobilized pH gradient gel 3-10) ,SDS-PAGE as the second direction to execute 2D electrophoresis, and PDQuest 1.0 software was used to analyze 2D electrophoretogram. Results The protein spots in Toxoplasma gondii infected mice and normal paired mice were (132 ±10) and (170 ± 13) , respectively. After the analysis by PDQuest 1. 0 software, only 19 protein spots were found to express in infected mice and only 37 protein spots were found to express in normal paired mice. Additionally, the obvious quantitative changes in a part of proteins of the cerebrum in the both group occurred. Conclusion There are obvious changes in cerebral proteins from mice with acute Toxoplasma gondii infection, which provids useful clues for studying the cerebral proteins injury in acute Toxoplasma gondii infected mice and the new cure drug.
