How Cells React to DNA Damage: MDC Researchers Decode Dual Signaling Pathway for the Activation of the Survival Factor NF-kappaB

Upon damage to the genomic DNA, repair enzymes and gene regulators are activated that determine the fate of the affected cells. Researchers of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have now shown how the transcription factor NF-kappaB, which coordinates a cellular survival program, is activated by DNA damage. Dr. Michael Hinz, Dr. Michael Stilmann and Professor Dr. Claus Scheidereit have uncovered a dual signaling pathway which is used for signal transmission. DNA damage-induced NF-kappaB activation is associated with the resistance of cancer cells to radiation and chemotherapy. (Molecular Cell, DOI 10.1016/j.molcel.2010.09.008)*.

New Insights into the Development of Epithelial Cells

Scientists of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch and the Experimental and Clinical Research Center (ECRC) of MDC and Charité in Berlin-Buch have gained new insights into the development of epithelial cells and their molecular repertoire. Dr. Max Werth, Katharina Walentin and Professor Kai Schmidt-Ott have identified a transcription factor (grainyhead-like 2, Grhl2), which regulates the composition of the molecular “bridges” that link adjacent epithelial cells. The authors were able to demonstrate that Grhl2, via DNA-binding, directly regulates the expression of two such cell junctional molecules, E-cadherin and claudin 4.

New Findings on Multiple Sclerosis - Immune Cells Also Attack Neurons Directly

Researchers in Germany have gained new insight into how the immune system causes damage associated with multiple sclerosis (MS), an incurable neuroinflammatory disorder. Using imaging tools which enable investigation of processes in living organisms, they were able to show a direct interaction between immune cells and neurons which plays a significant role in neuronal injury. However, this direct interaction may respond to therapeutic intervention. The study by Dr. Volker Siffrin and Professor Dr. Frauke Zipp (formerly Max Delbrück Center for Molecular Medicine, MDC, Berlin-Buch, now University Medical Center Johannes Gutenberg University, Mainz) has now been published in the journal Immunity (DOI 10.1016/j.immuni.2010.08.018)*.

More Cancer-Fighting Power – Mouse with Highly Effective Components of the Human Immune System - Ten Years of Developmental Work by MDC and Charité Researchers

How can the immune system be made more potent against cancer? To solve this crucial question, Dr. Liang-Ping Li and Professor Thomas Blankenstein of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch and Charité – Universitätsmedizin Berlin in Germany have dedicated ten years of research to develop a new method. The researchers modified T cell receptors (TCRs), the antenna-like structures of T cells, so that they would no longer ignore cancer cells, but instead specifically track and recognize them. This modification is the precondition for the immune system to destroy cancer cells. The researchers developed a mouse with a whole repertoire of these human T cell receptors (Nature Medicine, doi: 10.1038/nm.2197)* with the aim of utilizing these receptors in the future for targeted immunotherapy in patients.

Neural Stem Cells Attack Glioblastoma Cells

In their latest research, scientists of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have demonstrated how the brain’s own stem cells and precursor cells control the growth of glioblastomas. Of all brain tumors, glioblastomas are among the most common and most aggressive. Dr. Sridhar Reddy Chirasani, Professor Helmut Kettenmann and Dr. Rainer Glass (all MDC) and Dr. Michael Synowitz (Charité – Universitätsmedizin Berlin) have now shown in cell culture and mouse model experiments just how the body’s own protective mechanism they identified in an earlier study, actually works (Brain, July 6, 2010, doi:10.1093/brain/awq128)*.

FMP and MDC Researchers Identify a Fundamental Process in Lysosomal Function and Protein Degradation - Disorder Leads to Serious Diseases

 

The degradation of proteins and other macromolecules in cells is vital to survival. Disruption of this process can result in serious disease. The research group of Professor Thomas Jentsch (Leibniz Institute for Molecular Pharmacology, FMP/ Max Delbrück Center for Molecular Medicine, MDC, Berlin-Buch) has now succeeded in identifying an essential cellular process necessary for the transport and degradation of macromolecules in endosomes and lysosomes, respectively. In two studies published in the same issue of the journal Science, they showed that – contrary to scientific consensus –the function of these tiny cell organelles not only depends on the pH, but also on chloride ion accumulation in their interior (Science 11 June 2010, Vol. 328. no. 5984, pp. 1398-1401; DOI: 10.1126/science.1188070; pp. 1401-1403, DOI: 10.1126/science.1188072; originally published in Science Express on 29 April 2010)*.

A Clamp for Emerging Flu Viruses - Researchers in Freiburg and Berlin Unravel Secret of Innate Immune Response

 

When the human body becomes infected with new influenza viruses, the immune system rapidly activates an inborn protective mechanism to inhibit the intruding pathogen. A protein known as Mx plays an important role in this process, keeping the spread of viruses in check. Exactly how Mx accomplishes this task was previously unknown. Now virologists from the Institute of Medical Microbiology at the Freiburg University Medical Center and biochemists from the Max Delbrück Center for Molecular Medicine (MDC) in Berlin-Buch, Germany, have unraveled the structure of the Mx protein and are able to explain how it develops its anti-viral effect (Nature, doi: 10.1038/nature08972)*.

Two at One Stroke – How Cells Protect Themselves from Cancer

New Findings of MDC and Charité Researchers

 

Cells have two different protection programs to safeguard them from getting out of control under stress and from dividing without stopping and developing cancer. Until now, researchers assumed that these protective systems were prompted separately from each other. Now for the first time, using an animal model for lymphoma, cancer researchers of the Max Delbrück Center (MDC) Berlin-Buch and the Charité – University Hospital Berlin in Germany have shown that these two protection programs work together through an interaction with normal immune cells to prevent tumors. The findings of Dr. Maurice Reimann and his colleagues in the research group led by Professor Clemens Schmitt may be of fundamental importance in the fight against cancer (Cancer Cell, Vol. 17, Issue 3, 16 March 2010, pp. 262-272; DOI 10.1016/j.ccr.2009.12.043)*.

MDC Researchers Link Protein Tether to Touch Perception - Tiny Protein Filament Opens and Closes Ion Channels

Humans and animals are able to perceive even the slightest vibration and touch of the skin. Mechanosensitive ion channels play a crucial role in the mediation of these sensations. Ion channels are pores in the cell membrane which are highly responsive to external signals. Mechanosensitive ion channels open at the slightest vibration and allow ions (electrically charged particles), to cross the cell membrane, which causes an electrical current until the channel closes again. Until now it was unclear how the ion channels were opened. Dr. Jing Hu and Professor Gary Lewin of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have now discovered the presence of a protein filament that causes the ion channels to open and shut like a tethered gate (EMBO Journal,Vol. 29, No. 4, pp 855-867; doi: 10.1038/emboj.2009.398)*.

MDC Researchers Develop New Tool to Investigate Ion Channels - Application of Neurotoxins of Cone Snails and Spiders

 

Neurotoxins from cone snails and spiders help neurobiologists Sebastian Auer, Annika S. Stürzebecher and Dr. Ines Ibañez-Tallon of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, Germany, to investigate the function of ion channels in neurons. Ion channels in the cell membrane enable cells to communicate with their environment and are therefore of vital importance. The MDC researchers have developed a system which for the first time allows the targeted, long-lasting investigation of ion channel function in mammals and also the blockade of the ion channels with neurotoxins. In transgenic mice they succeeded in blocking chronic pain by introducing a toxin gene into the organism (Nature Method, doi:10.1038/NMETH.1425)*.

Sealed Off

The cerebral ventricles filled with fluid act like shock absorbers, protecting the brain against damage from concussion or blows. Researchers of the Max Delbrück Center (MDC) and the Leibniz Institute for Molecular Pharmacology (FMP) in Berlin-Buch have now demonstrated how these brain ventricles develop prior to the establishment of the blood-brain barrier in zebrafish. One specific protein (Claudin5a) is decisive for this development. It forms a barrier between the nervous tissue and the ventricles. If Claudin5a is absent, the ventricles cannot expand and the brain morphogenesis of the animals is disrupted. According to the researchers, these insights can be used for tests on the penetrability of drugs into the brain. (PNAS, doi:10.1073/pnas.0911996107)*.
