TNC-targeted CAR-macrophage therapy alleviates liver fibrosis in mice.

ABSTRACT:

Background

Tenascin-C (TNC) is an extracellular matrix (ECM) protein involved in tissue damage and fibrosis. Chimeric antigen receptor (CAR) cell therapy is a novel therapeutic approach that has attracted increasing attention in recent years. Here, we engineered CAR-macrophages targeting TNC (TNC-CAR-Ms) and explored the underlying mechanism through which TNC-CAR-Ms treat liver fibrosis.

Methods

The role of TNC in liver fibrosis was studied in established Tnc knockout (KO) and littermate control mice. A TNC-targeted single-chain variable fragment (scFv) was designed to generate TNC-CAR-Ms and evaluate their biological function. The phagocytosis and killing effects of TNC-CAR-Ms were tested in vitro, while the antifibrotic efficacy and safety of TNC-CAR-Ms were evaluated in v
