In the version of this article initially published, Fig.3b,c, Fig. 5a–d, Extended Data Fig. 1 and Supplementary Fig. 8b contained errors. Fig. 3b and c showed incorrect immunohistochemistry quantifications. Fig. 5a contained a duplicate image for the TMEM119 control sample, and panels b and c showed incorrect immunohistochemistry quantifications. Fig. 5d contained an incorrect image for the t-SNE map of P2RY12; it was a duplicate of the map for HLA-DRA. Extended Data Fig. 1 contained incorrect images in panel a for Pat 7 (TMEM119), Pat 12 (TMEM119, CD74) and Pat 15 (CD68) and in panel b for Pat 3 (GFAP), Pat 12 (TMEM119 and P2YR12) and Pat 13 (TMEM119). Supplementary Fig. 8b contained an incorrect image for the CSF2 t-SNE panel.

In addition, the legend for Fig. 5b as well as the description of Fig. 1b in Methods incorrectly said that the test used was a paired t-test; it should read ‘unpaired t-test’ in both places. In the Results section, the sentence “Normalization for the number of IBA1+ cells revealed lower expression of the bona fide microglial markers P2RY12 and TMEM119, and higher expression of HLA-DR (Fig. 5c)” should read “no change of expression” instead of “lower expression”.
