FIG. 4.

Quantification of IFN profile transcripts of BMMs from ISCL and parental mice treated with B. burgdorferi. The expression of transcripts was evaluated by RT-PCR 24 h following the addition of B. burgdorferi to confluent cultures of BMMs. Transcript levels in duplicate wells treated with medium or B. burgdorferi were normalized to β-actin transcript levels. Values shown in this figure are means ± standard deviations and are representative of results from three experiments. One-way analysis of variance revealed that values for macrophages from congenic mice were not different from values for macrophages from the predominant wild-type parent, as confirmed with the Bonferroni multiple-comparisons test.
