Cell type–specific impact of lysosomal acid lipase (LAL) deficiency and the potential role of cell–cell communication via transferable LAL enzymes. Bradić et al. found that hepatocyte-specific LAL deficiency in mice was not sufficient to markedly alter the hepatic proteomic signature and phenotypes when mice were fed a standard laboratory chow diet. The modest phenotype of hepatocyte-specific Lal−/− mice on a chow diet is likely due to the presence of residual acidic CE hydrolase activity in liver lysates. The residual hepatic LAL activity may originate from Kupffer cells and recruited macrophages, as well as circulating LAL produced by other organs. The respective contributions of each source and the mechanism by which LAL enzymes are transferred to hepatocytes remain to be further elucidated. The figure is created with BioRender.com.
