Abca7 deficiency suppresses inflammatory cytokine expression in the mouse brain on peripheral LPS administration. mRNA expression levels of inflammatory cytokines were analyzed in the cortex (CX; A–C) and hippocampus (HP; D–F) of control (white), Abca7+/− (gray), and Abca7−/− (black) mice at 3.5 h after administration with i.p. LPS injection (control, n = 15; Abca7+/−, n = 17; Abca7−/−, n = 9) or without i.p. LPS injection (control, n = 16; Abca7+/−, n = 18; Abca7−/−, n = 7). The ∆∆Ct values of Il6 (A and D), Tnf (B and E), and Il1b (C and F) relative to Hprt were measured by qRT-PCR. Relative ratios to control mice without LPS administration are shown as mean ± SEM. *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001, Tukey–Kramer post hoc analysis of 2-way ANOVA within LPS(−) or LPS(+) groups.
