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 cells it conferred specificity for GPC3, the HCC-associated antigen. Thus, it enables HLA-A2+ patient's T cells to specifically kill GPC3+ HCC.
Systemic treatments for advanced stage HCC are constantly evolving and current approaches include drug treatment with sorafenib - yet the current standard of care still does not offer a strong enough prognosis for patients. Liver transplant is an option for only 10 -15% of HCC carriers diagnosed at an early stage and therefore the importance of other treatment options for patients is critical. This is a treatment gap that adoptive T-cell therapy could potentially fill.

About The International Liver CongressTM 2014
The International Liver Congress™ 2014, the 49th annual meeting of the European Association for the study of the Liver, is being held at ExCel London from April 9 – 13, 2014. The congress annually attracts in excess of 9000 clinicians and scientists from around the world and provides an opportunity to hear the latest research, perspectives and treatments of liver disease from principal experts in the field.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
