Table 1 Effects of morphine and/or HIV-1 Tat exposure ± fractalkine on the percentage of microglia in mixed-glia cultures from striata of Cx3cr1-/- (Cx3cr1GFP/GFP) mice ().

From: Fractalkine/CX3CL1 protects striatal neurons from synergistic morphine and HIV-1 Tat-induced dendritic losses and death

  1. No significant effects of morphine and/or HIV-1 Tat ± fractalkine (1 μg/ml) exposure on the proportion of GFP+ microglia were noted; effects were compared using 2-way ANOVA.
  2. § The proportion of microglia in mixed glial cultures from Cx3cr1-/- mice was much greater than percentages seen in equivalent striatal cultures from wild-type mice (e.g., 8.8 ± 0.6% Iba-1+ microglia in control cultures) determined as part of another study [60].
