Novel APOE+ trained immunity mechanism; human translational validation needed

beta-glucan elicits APOE-dependent peripheral trained immunity to suppress hepatocellular carcinoma.

A immune-boosting sugar particle combined with checkpoint immunotherapy shrank liver tumors more effectively than either treatment alone in preclinical models.

Whole beta-glucan particle preconditioning induces a trained immunity phenotype in APOE-positive hepatic macrophages, reducing lipid accumulation and endoplasmic reticulum stress to enhance antitumor function in orthotopic HCC models. Combination with anti-PD-L1 achieves superior tumor control vs either monotherapy, with the mechanism validated in human monocytes supporting translational applicability.
