When transmembrane form of tumor necrosis factor (mTNF) interacts with its cognate receptors or agonistic antibodies signaling pathways are activated in the ligand expressing cells. This "reverse signaling" appears a fine-tuning control mechanism in the immune response. Despite a clinical relevance key molecules of TNF reverse signaling and their functions(More)
Elevated expression of the inducible heat shock protein 70 (Hsp70) is known to correlate with poor prognosis in many cancers. Hsp70 confers survival advantage as well as resistance to chemotherapeutic agents, and promotes tumor cell invasion. At the same time, tumor-derived extracellular Hsp70 has been recognized as a "chaperokine", activating antitumor(More)
A poly(dimethylsiloxane) (PDMS)-based biochip with an integrated pressure controlled positioning system with sub-micrometre precision was realized. The biochip was easy and cheap to manufacture and enabled positioning in a wet environment. It allowed the application of total internal reflection fluorescence (TIRF) microscopy at the dorsal cell membrane,(More)
Peptide ligands have great potential as selective agents for diagnostic imaging and therapeutic targeting of human cancers. A number of high-throughput assays for screening potential candidate peptides have been developed. Although these screening assays are indispensable for the identification of peptide ligands at a large scale, it is crucial to validate(More)
