In this article, which shows the development of senolytic CAR T cells, there was an inadvertently duplicated micrograph panel in Fig. 4a. This panel shows that a NASH-inducing diet increases SA-b-gal-positive cells in the liver. Owing to a labelling error, the micrograph showing the liver of control chow diet-treated mice was incorrectly the same as that of the liver of control peanut oil-treated mice from Extended Data Fig. 2m. A revised version of Fig. 4a with the correct micrograph showing SA-b-gal staining in the liver of control chow diet-treated mice is now provided in the HTML and PDF versions of the article, and supports the original conclusions that treatment with NASH diet increases SA-b-gal-positive cells in the liver. We apologize for any confusion that this error may have caused.
