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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
