Tumor vaccination against hepatoma: How does it work?
Shuichi Hanada, Takaji Wakita, Hiroshi Takahashi – 1 November 1994 – Fusion of BERH‐2 rat hepatocellular carcinoma cells with activated B cells produced hybrid cells that lost their tumorigenicity and became immunogenic. Syngeneic rats injected with BERH‐2‐B hybrid cells became resistant to challenge with parental BERH‐2 cells, and rats with established BERH‐2 hepatomas were cured by subsequent injection of BERH‐2‐B cells. Both CD4 and CD8+ cells were essential for the induction of protective immunity; however, only CD8+ cells were required for the eradication of BERH‐2 tumors.
