Significant new data presented today at the International Liver Congress 2014 indicate that liver cancer (Hepatocellular Carcinoma (HCC)) may be treated by adoptive T-cell therapy.
This new therapeutic approach in the treatment of HCC could be very important as without treatment the 5 year survival rate is just 5%. Globally, HCC accounts for 746,000 deaths, and in the UK alone is responsible for over 4,000 deaths per year.
Glypican-3 (GPC3) is a tumour associated antigen expressed in up to 70% of HCC but not in healthy human tissue. Isolating GPC3-specific T-cell receptors and expressing them on patient’s T-cells can help treat HCC, as these T cells can recognise and eliminate GPC3-postive HCC.
The study detected and expanded MHC-multimer-positive CD8+ T-cells specific for targeted GPC3 epitopes and grew T-cell clones. From these clones, the most specific and active T-cell receptor was isolated. When this T-cell receptor was expressed on donor T…
