Adoptive T-cell therapy is a very promising approach in the treatment of cancer. Early phase clinical trials with genetically engineered T-cells expressing a tumor-specific chimeric antigen receptor (CAR) show significant efficacy in the treatment. However, currently used CAR modified T-cells for antigen-directed targeting towards tumor cells have insufficient performance in the anti-tumor attack, e. g. less amplification and cytolytic activity after the transfer of the modified T-cells into the patient. Scientists from the University Medical Center of Cologne developed a bispecific CAR, which improves the performance of genetically engineered T-cells expressing these CAR polypeptides on their surface. The bispecific CAR comprises two antibody units, with one antibody unit being an anti-CD30 single chain antibody unit and the other antibody unit being an antibody unit specific for an antigen present on the surface of a predetermined target cell, e. g. for the tumor carcino-embryonic antigen (CEA) on breast cancer cells.

Meanwhile scientists identified many more secondary metabolites like Erythromycin, an antibacterial drug. The enormous relevance of these natural products in…

Biological coatings have a high potential for manifold applications, especially for medical applications or biodegradable coatings. Up to now, the formation of biological coatings is accompanied either by a low control over film formation or connected to high costs. Current challenges that need to be overcome are a high control over the film thickness, an even and continuous coating of objects with a complex geometry, or the site-specific coating of single areas on one object. The new concept Enzymatic Bio-Coating is able to solve these Problems. Suitable supports are: Glass, wood, and miscellaneous plastics and metals.
Casein layers are antibacterial, edible, and renewable.

Auf Grundlage eines neuen Oxidationsverfahrens wurden Gassensoren entwickelt, die ohne die sonst notwendige Sensorheizung auskommen. Das besondere Verfahren der potentiostatisch und galvanostatisch kontrollierten plasma-elektrolytischen Oxidation (PEO) ermöglicht dabei die Herstellung einer mechanisch stabilen TiO2-Schicht mit exzellenter Adhäsion auf einer Titanfolie.
