Fig. 7From: Innate immune responses after stimulation with Toll-like receptor agonists in ex vivo microglial cultures and an in vivo model using mice with reduced microgliaTranscription of genes encoding TLR4, TLR7, and TLR9 in adult mouse brain with and without PLX5622 treatment after acute TLR agonist or PBS exposure. Expression of Tlr4, Tlr7, and Tlr9 was measured by qRT-PCR in mouse brains either treated with PLX5622 (+) or untreated (−) for 28 days prior to a 6-h exposure to LPS, IMQ, CpG-ODN 1585 (CpG), or PBS as a control. The Delta CT was plotted for each cohort where each dot represents a single mouse assayed. LLOD lower limit of detection of transcript based on a CT cutoff value of 35. Statistical analysis was performed using a Student’s t test on the mean Delta CT to compare PLX5622-treated (reduced microglia) to untreated mice. ****P ≤ 0.0001; *P ≤ 0.05, ns not significantBack to article page
