Figure 5From: Genomic locus on chromosome 1 regulates susceptibility to spontaneous arthritis in mice deficiency of IL-1RAProduction of cytokines by spleen cells from 4 month old mice. Cells were harvested from individual mice of each strain and cultured with CD3/CD28 stimulation beads. Culture supernatants were harvested after 48 hours and assayed for the cytokines indicated. Each bar represents the mean and standard deviation of 3 biologic replicates. Differences between groups were calculated by Student’s T test.Back to article page
