Kristian Berg awarded the 2007 Pater-Leander-Fischer prize for PCI paper
Kristian Berg and his team – the PCI group at the Department of Radiation Biology – has recently been awarded the 2007 Pater-Leander-Fischer prize for the paper “Photochemical internalization (PCI): A novel technology for activation of endocytosed therapeutic agents”. This article was judged by the "Deutsche Gesellschaft für (DGLM) as the best publication in the journal “Medical Laser Application”.
Kristian Berg received the Pater-Leander-Fischer prize during the 16th Annual Meeting of the DGLM, which took place in Munich from 17th to 18th of June in Munich, where he also gave a lecture.
Berg emphasizes that their scientific progress in the PCI field is a result of a group effort.

Photochemical Internalization (PCI):
|Co-administration of drugs||Endocytosis||Sequestration of drug|
|ROS generation||Cytosolic release (PCI)||Drug-target interaction|
Figure: Photochemical internalization (PCI) is an efficient drug (D) delivery system based on photodynamic therapy (PDT), a photochemical method generating reactive oxygen species (ROS) after light activation of a photosensitizer (S). The main PDT-induced ROS product is singlet oxygen, which can destroy a number of biomolecules including membrane lipids and proteins of endosomes and lysosomes. Photochemical disruption of endocytic vesicles leads to release of the drug to the cytosol where it can reach its targets (T).
