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.

EASL is the leading European scientific society involved in promoting research and education in hepatology. EASL attracts the foremost hepatology experts and has an impressive track record in promoting research in liver disease, supporting wider education and promoting changes in European liver policy.
EASL's main focus on education and research is delivered through numerous events and initiatives, including:
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.

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.
As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...

The Atlantic overturning is one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards. Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe.
Scientists now found evidence for a slowdown of the overturning – multiple lines of observation suggest that in recent decades, the current system has been...
Because they are regularly subjected to heavy vehicle traffic, emissions, moisture and salt, above- and underground parking garages, as well as bridges, frequently experience large areas of corrosion. Most inspection systems to date have only been capable of inspecting smaller surface areas.
