Fig 2: Expression of the a-2-HS-glycoprotein (AHSG) and transthyretin (TTR) proteins in the brains of Il18-/- and Il18+/+ mice. Representative immunoblots showing the expression levels of (a) AHSG and (b) TTR in the prefrontal cortex (PFC), hypothalamus, and hippocampus of Il18-/- and Il18+/+ mice. (a) AHSG expression did not differ significantly. (b) TTR expression in the PFC of Il18-/- mice was significantly lower than in Il18+/+ mice. For the hypothalamus, ACTB expression was measured after stripping the blot after detection of TTR or AHSG. n = 6 per group; *P < 0.05.
