One the most common types of leukemia is chronic lymphocytic leukemia. To find the right treatment for an individual patient with that disease is a challenging task and many patients develop a resistance against the existing drugs. The purpose of the research presented by BRIGITTE VOIT in this video is to find new drugs that reduce cancer cells while not destroying other cells in the body. The researchers created two [...] Watch video

Stroke is one of the most frequent neurological disorders, befalling over 250.000 persons each year in Germany alone. The research underlying this video explores the role of non-invasive methods for stroke diagnosis and therapy. The use of functional Magnetic Resonance Imaging (fMRI), which produces image-signals on the basis of the oxygen-concentration in the blood, allows for the detection of increased or decreased [...] Watch video

The use of continuum robots – robots that are not composed of rigid links and joints but are continuously bending structures – opens up completely new possibilities for surgery: With this tool surgeons can reach locations in the human body which they would not be able to reach with traditional surgical instruments. This enables them to e.g. remove brain tumors in a minimally invasive way. There are a vast number of [...] Watch video

Autism spectrum disorders are largely of genetic origin, and 5-10% of cases are currently known to be caused by a single gene mutation. Understanding the consequences of these mutations in detail can open the way for medical treatment. The study presented in this video focused on how a frequent mutation seen in patients with autism spectrum disorders causes the brain dysfunction that leads to the behavioral symptoms.

Parts of the human RNA that are not translated into proteins may still have an important function. As SVEN DIEDERICHS explains in this video, the occurrence of the RNA gene Malat-1 makes the difference between lung cancer with and without metastasis. By first identifying Malat-1 as the molecular difference between patients and then silencing this RNA gene, it was found that Malat-1 could be a viable target to suppress [...] Watch video

The research presented in the video investigates how endosomes are able to transport material back to the cell surface in a process called recycling or endosomal exocytosis. In order to do so, endosomes have to have their own identity which is defined by a phosphoinositide, Phosphatidylinositol 3-phosphate (PI3P). To deliver the material to the cell surface the endosomes have to get [...] Watch video

Our immune system has evolved many different cells with different functions to prevent infections. One of these functions is cellular cytotoxicity; this means that cells are able to kill other cells. Natural killer cells (NK cells) are one type of these cells that can achieve cytotoxicity. CARSTEN WATZL experiments with NK cells in order to find out how they protect themselves from their own cytotoxic machinery and how [...] Watch video

Streptococcus pneumoniae kills millions of people worldwide. For the subgroup serotype 8, prevalent in the United States and Western Europe, there is no vaccine to date. In this video, PETER H. SEEBERGER explains the approach of his research group to create a synthetic sugar vaccine against this bacterial infection that works in mice. They relied on synthetic chemistry to assemble sugar chains from monomers; the [...] Watch video

Molecules in cells are not randomly distributed but form compartments that perform specific functions. A few years ago, scientists discovered that many of these compartments develop by the process of phase separation which results in liquid-like compartments. This is the case for stress granules – drops formed by the cell when it is under stress, e.g. from heat or chemicals. As ANTHONY A. HYMAN explains, it has been [...] Watch video

The technique of Magnetic Resonance Imaging, or short MRI, is a useful and widely used tool in clinical diagnostics. However, the current MRI techniques are not sensitive enough to detect low concentrations of drugs or disease related molecules. LEIF SCHRÖDER explains that MRI is typically based on the detection of water molecules. However, the high water concentration that is always present in the body creates a strong [...] Watch video

T cells are an important component of the body’s immune system. As ERIKA PEARCE explains, there are several types of T cells which form consecutively during the immune response and serve different purposes. Effector T cells combat pathogens from infections or tumors while memory T cells provide protective immunity to prevent re-infection or reoccurring cancer. The research presented in this video investigates how the [...] Watch video

High-level athletes, such as basketball and volleyball players, show more than fifty percent prevalence of developing tendinopathy – an injured tendon – compared to the normal population.

Almost everybody has to deal with stress sometimes. But what is stress? It is a reaction of the body to a challenging situation which elicits a stress response in the body. Stress is also a risk factor for disease and this is an area that MATHIAS V. SCHMIDT and his research team focus on. The most prominent stress-related disorders are psychiatric disorders and metabolic disorders. Specifically, as Schmidt explains in [...] Watch video

All cells in our bodies contain the same genetic information. Yet, these cells make up very different parts of the body like liver, heart, and eyes. This is achieved by expressing certain genes and inactivating others. The protein MOF is known to play an important role in this process: DNA does not flow freely in the cell nucleus but is packaged by histone proteins. There, MOF facilitates reading the genetic information [...] Watch video

Each year 1.5 million people die of tuberculosis thus making it the number one killer of all contagious diseases. With the number of multi-resistant tuberculosis growing, currently available treatments are no longer as effective as they used to be.
