Abstract:
Toxoplasma gondii infection elicits a Th1-biased inflammatory response.As the protection induced by T.gondii vaccine is highly correlated with the systemic T-cell immune response, here we detected the cellular immune responses in chronically infected BALB/c mice.Splenocytes collected from chronically infected mice exhibited stronger lymphocyte proliferation after the stimulation of cells with soluble tachyzoite antigens.What is more, IFN-γsecretion was detected in CD3 +T, CD4 +T and CD8 +T cells after the stimulation of splenocytes with antigens.In summary, T.gondii chronic infected mice showed stronger systemic T-cell immune response, which would provide valuable data for the evaluation of the efficiency of T.gondii vaccine.
