In vitro studies have demonstrated that GM-CSF in combination with other stimulatory factors induces a microbicidal response that control T. gondii infection. We assessed whether GM-CSF alone can control T. gondiireplication in murine microglial cultures. Microglia were collected and cultured with or without GM-CSF and the half of each group was infected with T. gondii. We determined the T. gondii infectivity, cytokines levels, NO and superoxide detection.GM-CSF alone primes microglia, which after infection induces the production of TNF-α and IL-6, leading to NO and superoxide production, without any stimulus from IL-12p70 and IFN-γ.
