Complementary DNA (cDNA) was synthesized by a Verso cDNA RT kit (Cat# AB1453B, Thermo Scientific) per the manufacturer's protocol. Real-time PCR for target mRNAs was performed using TaqMan gene expression assays for Lipocalin 2 (Lcn2, Mm01324470_m1), Ccl2 (Mm00441242_m1), Ccl7 (Mm00443113_m1), Gbp2 (Mm00494576_g1), IL-1β (Mm0133-6189_m1), Myc (Mm00487804_m1), IL-6 (Mm00446190_m1), suppressor of cytokine signalling 3 (SOCS3, Mm00545913_s1), C5ar1 (Mm00500292_s1), Trem2 (Mm04209424_g1), Ptgs2 (Mm00478374_m1), Nlrp3 (Mm00840904_m1), Mb21d1 (Mm01147496_m1), Tmem173 (Mm00727224_s), Tnfrsf1 (Mm00441883_g1), Fos (Mm00487425_m1), Tgm2 (Mm00436979_m1), Lamp1 (Mm01217070_m1), Pink1 (Mm00550827_m1), Apoe (Mm01307192_m1), Blnk (Mm01197846_m1), and GAPDH (Mm99999915_g1) (Applied Biosystems, Carlsbad, CA] on an QuantStudio™ 5 Real-Time PCR System (Applied Biosystems). Gene expression was normalized by GAPDH and compared to the control sample to determine relative expression values by the 2-ΔΔCt method 31 (link), 41 (link).
