Reduced expression of 2'-3'-cyclic nucleotide 3'-phosphodiesterase () in humans and mice causes white matter inflammation and catatonic signs. These consequences are experimentally alleviated by microglia ablation colony-stimulating factor 1 receptor (CSF1R) inhibition using PLX5622. Here we address for the first time preclinical topics crucial for translation, most importantly ) the comparison of 2 long-term PLX5622 applications (prevention and treatment) 1 treatment alone, ) the correlation of catatonic signs and executive dysfunction, ) the phenotype of leftover microglia evading depletion, and ) the role of intercellular interactions for efficient CSF1R inhibition.
