简介：
Overview
This article presents a protocol for the suppression of hepatitis B virus (HBV) replication in mice using adoptive cell transfer (ACT) of stem cell-derived viral antigen-specific T lymphocytes. The method emphasizes the use of iPSC-derived T cells with a naive phenotype and a single type T cell receptor.
Key Study Components
Area of Science
