Cd86), were down-regulated in Mettl3-deficient cells (Fig. 1G), suggesting that METTL3 has a critical function in controlling the innate immune response of Raw 264.7 macrophages. To further confirm the biological role of the m 6A modification in macrophages, Mettl3 conditional KO (CKO) mice were generated by crossing Mettl3 flox/flox mice with mice expressing Cre recombinase under the control of lysozyme 2 promoter ( Lyzm-Cre). We have documented the loss of both the METTL3 protein and the overall m 6A modification in bone marrow–derived macrophages (BMDMs) from Mettl3 flox/flox; Lyzm-C...

2Department of Health Studies, FH Joanneum University of Applied Sciences, Graz, Austria Huntington’s disease (HD) is caused by an expansion of CAG triplets in the huntingtin gene, leading to severe neuropathological changes that result in a devasting and lethal phenotype. Neurodegeneration in HD begins in the striatum and spreads to other brain regions such as cortex and hippocampus, causing motor and cognitive dysfunctions. To understand the signaling pathways involved in HD, animal models that mimic the human pathology are used. The R6/2 mouse as model of HD was already shown to present ...
