Differences in cytokine production by WT and Mayp^Lp/Lp macrophages. (A) Cytokine release by cultured WT () and Mayp^Lp/Lp (□) BMM. (B) Cytokine release in WT () and Mayp^Lp/Lp (□) BMMs stimulated with LPS for 24 hours. Duplicate measurements for BMMs from 2 mice of each genotype. Differences between WT and Mayp^Lp/Lp are significant (P < .05; Student t test; n = 4). No significant differences were seen for the other 34 cytokines tested and listed in “Materials and methods.”
