Targeted immune stimulation based on DNA Nanotechnology

DNA carrier systems
entering a cell

DNA is usually known as the genetic code for protein synthesis in all living organisms. The application of DNA as a molecular building block on the other hand, allows for the construction of sophisticated nanoscopic shapes that are built entirely from DNA. In particular the recent invention of the so-called DNA origami method facilitates the fabrication of almost all imaginable 3D shapes.

Now NIM member Prof. Tim Liedl (LMU München) and his team developed a DNA origami construct that serves as a carrier system to selectively stimulate immune responses of living cells. Together with the group of Prof. Carole Bourquin from the Klinikum der Universität München the biophysicists investigated the systematic immune stimulatory effect and the potential cytotoxicity of these DNA nanostructures.   Read more

Zeolite synthesis made easy

Zeolites are porous materials with perfectly regular pores and high surface area that can act as molecular sieves. This property has led to important applications including the purification of air or water such as the contaminated seawater around Fukushima. Zeolites are used as catalysts and for the separation and adsorption of numerous substances. Synthesis of one of the most attractive, stable zeolites with very large pores, called EMT, has so far required a very expensive template, which has precluded industrial applications. Now an international team of researchers including NIM member Prof. Thomas Bein (Department of Chemistry, Ludwig-Maximilians-Universität in Munich) has discovered a novel route for the synthesis of EMT from colloidal precursors at near ambient temperature within a short time.The results have been published in the current issue of Science Magazine.

The dynamics of transcription

NanoPositioningSystem

New methods allow visualization

In every living cell a complex system is continuously translating coded DNA into proteins. The first step in this process is called transcription. For each protein the so-called RNA polymerase produces a second version of the corresponding DNA segment (i.e. the gene): this product is referred to as messenger-RNA (mRNA). It serves as a model with which to build proteins. Recently an international team of scientists was able to visualize the dynamics of this complex transcription process. This was possible by using special fluorescence methods and a so-called nano-positioning-system. Jens Michaelis, a member of NIM, and his team were part of this project. The results are published in the latest issue of the journal Molecular Cell.

An important step towards highly effective drugs

Microscale thermophoresis paves the way for a new kind of drug-screening assay based on G protein-coupled receptors (GPCRs)

Receptor proteins located within the cell membrane serve to convey molecules or information into the interior. Because numerous drugs function by binding to such receptors, their interactions play important roles in the fight against various diseases. For example, the coupling can activate a signal chain which in the end specifically changes the metabolism of malignant cells. A collaboration between biophysicists from the LMU and researchers at the Massachusetts Institute of Technology (MIT) in Boston has found a very elegant and potentially revolutionary new way to screen for drug binding to membrane receptors. The Munich part of the project was led by scientists of the Nanosystems Initiative Munich (NIM) and of NanoTemper, a commercial spin-off of the LMU (PNAS Early Edition, May 12, 2011).

One of the scientists’ visions is that light could take over the role of electric current in future by building up optical circuits. This kind of circuit requires only minimal space and has the potential to widely exceed the capability and operating speed of electric circuits. Now NIM scientists have used a new model to demonstrate how to manipulate the direction of propagation of light or light energy at the level of single molecules. The biophysicists around professor Philip Tinnefeld (until fall 2010 at LMU Munich, now at TU Braunschweig) placed a cascade of four different fluorescent dye molecules on a platform of DNA. By means of a so-called "jumping dye" they can control the direction of the light path and hence of energy transfer. With their new single-molecule four-colour technique, the scientists made the success of the strategy clearly visible (JACS 2011).

A Quantum Pen for Single Atoms

Physicists around the world are searching for the best way to realize a quantum computer. Now scientists of the team around Stefan Kuhr and the NIM member Immanuel Bloch at the Max Planck Institute of Quantum Optics (MPQ) in Garching / Munich took a decisive step in this direction. They could address and change the spin of single atoms with laser light and arrange them in arbitrary patterns. In this way, the physicists strung the atoms along a line and could directly observe their tunnelling dynamics in a “racing duel” of the atoms (Nature 471, 2011) (Source: MPQ).

Pushing HIV out the door

How host factors aid in the release of HIV particles

Human Immunodeficiency Virus (HIV) – which causes AIDS – invades human immune cells and causes them to produce new copies of the virus, which can then infect new cells. A research team led by NIM researcher Professor Don C. Lamb (LMU Munich) and Priv.-Doz. Dr. Barbara Müller of Heidelberg University Hospital have now analyzed the involvement of particular components of the infected cell in virion release, and discovered that the enzyme VPS4A plays a more active role in the process than was previously thought. VPS4A was already known to act after virus budding was complete. Using an advanced microscopy technique, the group was able to show that complexes containing about a dozen VPS4A molecules form at points in the membrane at which newly assembled virions later emerge. According to Lamb, “We can now demonstrate in detail, for the first time, how host proteins interact with components of HIV, to enable them to bud from infected cells. Our ultimate goal is to elucidate the entire life cycle of the virus.” “With the methods we have at our disposal, we can also study the effects of drugs on infected cells, which may allow us to improve their efficacy or even lead to the development of new classes of active compounds.” (Nature Cell Biology online, 10 March 2011)

RNA Polymerase II

How the cell deals with transcriptional roadblocks

Gene transcription is central to cell function, as it converts the information stored in the DNA into RNA molecules of defined sequence, which then program protein synthesis. The enzyme RNA polymerase II (Pol II) is responsible for this genetic readout, but is prone to transcriptional arrest. NIM member Professor Patrick Cramer, Director of LMU’s Genzentrum, and his research associate Dr. Alan Cheung have now shown for the first time – and captured on film - what happens when Pol II arrests at a “roadblock”. They were even able to observe how transcript is reactivated. Reactivation of arrested transcriptional complexes is a normal part of the readout process, and is therefore of fundamental significance in all cells. Indeed, as Patrick Cramer points out, “It is also utilized to regulate gene activity in stem and tumor cells.” (Nature online, 23. February 2011)

Safe carriers

Modified mRNAs open up new therapeutical possibilites

Defects in the genome are the cause of many diseases. Gene therapy – direct replacement of mutant genes by intact DNA copies – offers a means of correcting such defects. Now a research team based at the Medical Center of the University of Munich, and led by the NIM Associate PD Dr. Carsten Rudolph, has taken a new approach that avoids DNA delivery. The team shows for the first time that chemical modification of mRNAs  provides a promising alternative to DNA-based procedures. mRNAs are messenger molecules and chemically very close to DNA.  In contrast to the latter, the modified RNAs do not increase the risk of cancer, and do not induce frequently observed severe immune reactions seen with DNA or unmodified mRNA.

Deciphering the conformational cycle of the chaperone BiP

A finishing school for proteins

Proteins are the cells´ "workhorses". But to fulfill their versatile functions they have to be folded in specific three-dimensional structures. So-called chaperons support these processes and prevent failures during the protein synthesis. Scientists around the NIM-member Professor Don C. Lamb (Department of Chemistry and Biochemistry, LMU München) and Professor Johannes Buchner (Department of Chemistry, TU München) identified how the important chaperone BiP changes its own structure and how it is influenced by the co-chaperone ERdJ3. The scientists present their results in the recent issue of the Journal Nature Structural & Molecular Biology.

The perfect wave

Surface acoustic waves convert cell membrane into nano-conveyor

Membranes protect  every single cell of our body and control exactly which substances are allowed to enter the cell. Illustrations often give the impression that membranes  are stiff formations. In reality they are as viscous as olive oil and moreover highly dynamic: This fact was used by the research groups of Professor Joachim Rädler (LMU), Professor Achim Wixforth (Universität Augsburg) and Professor Matthias Schneider (Boston University) through collaboration within the cluster of excellence “Nanosytems Initiative Munich (NIM)”. The scientists discovered that exposure to standing surface acoustic waves (SAWs) influences the distribution of the membrane´s lipids. The physicists could demonstrate that the new method also works for the separation of lipid-bound proteins: it can concentrate the proteins at predefined parts of the membrane, separate various kinds of proteins and, by using SAWs, transport them similar to conveyor  belts. This fact could be an important contribution for the realization of extremely small laboratories, so-called “Lab-on-a-Chip”. (NanoLetters, August 2010)

Highly concentrated right into the target

Cancer cells are hard to stop. They proliferate without control and thereby affect the healthy tissue. One possible way to fight their growth is to infiltrate the cells with anticancer agents. In close collaboration, three research groups of the Cluster of Excellence “Nanosystems Initiative Munich (NIM)” developed a method using nanoparticles to smuggle concentrated colchicine into the cells. Colchicine, a natural plant toxin from autumn crocus blocks the cell division and therefore stops the proliferation of cancer cells. The scientists of the Ludwig-Maximilians-Universität München used tiny porous silicate particles with an average size of about 50 nanometers. The porous silicate easily absorbs the colchicine and the particles are small enough to penetrate the cell membrane. To hinder the loss of agent on the particle’s way into the cell, the scientists developed a kind of protective layer. In only one synthesis step they were able to coat the nanoparticles with a lipid bilayer. Thereby the particles can effectively transport the colchicine through the cell membrane into the cell. This principle should be highly versatile, according to Prof. Bein:”Colchicine is only one example for many other agents that could be carried into the cells the same way”.

The attraction of gold

Electric voltage controls the chemical bonding of DNA

There are two ways to create nanostructures: scientists either split larger structures into pieces or they combine tiny building blocks to build new systems. In order to succeed in the latter approach they have to pick up the separate parts and place them with nanometer precision. Biophysicists at the Ludwig-Maximilians-Universität (LMU) München have now developed a technique for the exact arrangement of separate DNA molecules on a gold electrode, without any extensive preparation needed, neither for the gold surface nor for the DNA.
NIM scientist Hermann Gaub, Professor for Biophysics, and his group members made use of electro chemistry. By switching an electric voltage applied to the gold electrode, the researchers are able to control, whether the DNA binds chemically with the gold atoms or not. A negative voltage lets the molecule bind to the surface. A positive voltage leaves it free.

The world´s smallest building site

Tensegrity model on the nanometer scale

Light as a veil the tent roof of the Munich Olympic stadium seems to rest on its columns. Its construction proves that stable building is possible even with low material expense. It is the optimal stress distribution that really matters: compression-resistent and tension-stable building elements have to be arranged and connected in a way so that pressure and tension can balance within the system. Thereby the whole object is able to stabilise itself. The english made-up expression for this principle is „tensegrity“, a combination of tension and integrity. The world´s smallest artificial tensegrity structures are Tim Liedl´s topic of research. Since 2009 Liedl is professor for physics at the Ludwig-Maximilians-Universität München and member of the Cluster of Excellence "Nanosystems Initiative Munich" (NIM). During a research period at the Harvard Medical School, Boston, Tim Liedl and his local colleagues were able to rebuild a tensegrity model on the nanometer scale for the first time.

"Open nanoparticle!"

Programmable DNA-based valve for nanoparticles

Medical drugs often have to be given highly dosed, because much of the active agent is lost during its way throuh the body. But in many cases the high dose of the agent leads to unwanted side effects. In order to keep the dose as low as possible, the agents should ideally be transported through the organism directly to the desired destination, and be released there. Therefore the agent may be enclosed in nanoparticles, being opened at specific conditions. The NIM chemists Prof. Thomas Bein and Prof. Thomas Carell at LMU München have now found an easy way to produce silica particles, which open at a specific temperature. (Angewandte Chemie online, 11. Juni 2010).

Evolutionary logistics

How the first molecules could have met up

More than 3 billion years ago, the first forms of life on earth came into existence. The first complex chemical structures developed and formed the basis for the later protozoa. According to a scientific theory, this first step to life presumably took place in the oceans. But to build up complex structures, the dissolved and low- concentrated reactants had to meet each other. 

Now the LMU physicists Christoph Mast and Prof. Dieter Braun – both members of the NIM Cluster of Excellence - simulated the principle of these matching molecules in the lab. The scientists were thereby able to re-concentrate and also replicate dissolved genetic material purely by means of a temperature gradient. “Presumably similar thermal conditions have been existing inside of stone pores which lay close to warm submarine springs in the “Urmeer”, explains Braun. “Our examination is only a first step. For physicists like us it is extremely interesting to see how an equilibrium – as the homogenous distribution of molecules - has to be destabilized to breed live.

Oetzi´s beauty secret

Collagen fibrils

5300 years enclosure in a glacier could not harm the predominant part of the connective tissue of the tyrolean iceman “Oetzi”. Scientists from the Ludwig-Maximilians-Universität (LMU) Munich together with their colleagues from the European Research Academy (EURAC) at Bozen, Italy, demonstrated that the mummy´s collagen is almost identical with the collagen of a fresh skin sample. The reason for this exceptional conservation seems to be the freeze-drying of the Oetzi for thousands of years. In its’ recent publication, the group of PD Dr. Robert Stark, Department of Earth and Environmental Sciences, LMU, and member of the Nanosystems Initiative Munich (NIM), presents its’ studies on the molecular structure of collagen, the composition of molecule bundles, the collagen fibrils and on their elasticity.

Beyond the Quantum Limit

MPQ-LMU scientists create multi-particle entanglement of atoms in a Bose Einstein condensate on a microchip. The microcosm, the realm of quantum physics, is ruled by probability and chance. The behaviour of quantum particles cannot be predicted with certainty but only with certain probabilities given by quantum physics. This results in a so-called quantum noise, which fundamentally limits the precision of the most refined atomic clocks and interferometers. The solution to this problem is the use of entangled atomic systems. A break-through has now been achieved by a team around Professor Theodor W. Hänsch and Professor Philipp Treutlein (Ludwig-Maximilians-Universität Munich and Max Planck Institute of Quantum Optics in Garching, Philipp Treutlein is Professor at the Universität Basel since February 2010). For the first time the scientists succeeded in generating multi-particle entanglement on an atom-chip (Nature, Advance Online Publication, DOI: 10.1038/nature08988). This technique opens a way to significantly enhance the precision of chip-based atomic clocks or interferometers and could also form the basis for quantum computers on microchips. The Munich experiments have been carried out in cooperation with theoretical physicists around Dr. Alice Sinatra from the Ecole Normale Supérieure (ENS) in Paris.

NIM physicists invent the smallest electric motor world-wide

The principle is easy: one starter and one motor atom in a ring of laser light - and a bit of fine tuning, in order to keep moving into the right direction.

The research group around the theoretical physicist Prof. Peter Hänggi from the University of Augsburg has invented a concept for the minimal version of an electric motor, which runs on merely two atoms. The study has recently been published in the renowned scientific journal Physical Review Letters. An ordinary electric motor is based on the principle that mechanical work is done by electrical energy. Hänggi and his co-authors Dr. Alexey Ponomarev and Dr. Sergey Denisov have now transferred this principle into the nano world, even to the level of
