In view of the fact that the article ‘TGF-β signaling regulates neuronal C1q expression and developmental synaptic refinement’, by Allison R. Bialas and Beth Stevens, has been retracted by the authors (https://doi.org/10.1038/s41593-021-00877-7), we retract this News & Views highlighting the study, because it relied on the validity of the data presented therein.
