One of the many reasons tumors are so difficult to treat is that they are able to adapt whenever they are exposed to unfavorable conditions. Hypoxia, or a lack of oxygen, is one example of a phenomenon that should weaken the tumor, but instead, the malignant cells are able to compensate and drive more aggressive disease behavior.
Australian researchers have made a world-first breakthrough in the early detection of patients' resistance to a common treatment for chronic myeloid leukemia. The discovery offers some hope that the patients' treatment could be changed sooner to improve their chances of survival.
A new, epidemic strain of C. difficile is proving alarmingly deadly, and new research from the University of Virginia School of Medicine not only explains why but also suggests a way to stop it.
They may be slimy, but they are a perfect environment for microorganisms: biofilms. Protected against external influences, here bacteria can grow undisturbed, and trigger diseases. Scientists at Kiel University, in cooperation with colleagues at the Hamburg University of Technology (TUHH) in Hamburg-Harburg, are researching how it can be possible to prevent the formation of biofilms from the…
As part of a national, joint research project in cooperation with Chronix Biomedical (San Jose, CA/USA/Göttingen/Germany), Professor Michael Oellerich MD is on new biomarkers in organ transplantation, aiming to develop personalised immunosuppression for patients. This also entails the development of molecular test procedures, among others for the early detection of rejection. The keyword here is…
Many drug treatments do not work due to their poor ability to reach their intended targets inside patients’ cells. To address this, researchers at Cardiff University’s Schools of Pharmacy and Pharmaceutical Sciences, and Biosciences have designed a highly efficient method to improve the delivery of therapeutic molecules into diseased cells such as those in stomach cancer, breast cancer and…
A receptor, first known for its role in mediating the harmful effects of the environmental pollutant dioxin in our body, is now understood to play other important roles in modulating the innate immune response.
Researchers at Massachusetts Institute of Technology research center in Singapore have developed a new microfluidic device that tests the effects of electric fields on cancer cells. They observed that a range of low-intensity, middle-frequency electric fields effectively stopped breast and lung cancer cells from growing and spreading, while having no adverse effect on neighboring healthy cells.
A new nano-fabricated platform for observing brain cancer cells provides a much more detailed look at how the cells migrate and a more accurate post-surgery prognosis for brain cancer (glioblastoma) patients.
Hepatitis B virus (HBV) causes hepatitis B, an infectious disease that afflicts 230 million people worldwide, thereof 440 000 in Germany. Persistence of the virus in liver cells leads to progressive organ damage in the patient and contributes to a high risk of cirrhosis and liver cancer development. Providing a new paradigm to hepatitis B understanding, researchers at the German Cancer Research…
Researchers at the University of Bonn and the Ludwig-Maximilians-Universität of Munich have decoded a new mechanism of how the immune system can specifically attack pigmented cells of the skin. It was previously believed that natural killer cells did not have an immunological memory for the body's own tissues. However, the scientists have now showed that these immune cells can indeed…
Scientists from the University of Zurich have been able to understand for the first time why many cancer cells adapt relatively quickly to the treatment with therapeutic antibodies in invasive forms of breast cancer. Instead of dying off, they are merely rendered inactive. The researchers have now developed an active substance that kills the cancer cells very effectively without harming healthy…
A team from the International School for Advanced Studies (SISSA) in Trieste has obtained very promising results by applying gene therapy to glioblastoma. Tests in vitro and in vivo on mice provided very clear-cut results, and modelling demonstrates that the treatment targets at least six different points of tumour metabolism. Gene therapy, a technique that selectively attacks a tumour, might…
In brief, the new method involves exposing cells to ultrasound when they flow through a so-called micro-channel inside a chip. The individual cells are separated in the acoustic field and by studying the cells’ lateral movement at the end of the channel it is possible to identify the acoustic properties of the cells. Conversely, if you know the cells’ acoustic characteristics, you can detect…
Scientists from the universities in Münster and Munich have discovered what precisely goes wrong in the body in the case of multiple sclerosis (MS). At the same time the neuroscientists were able to demonstrate that for MS, which occurs in bouts, there is a therapy which is tailor-made to eliminate the deficit.
The sharing of genetic information from millions of cancer patients around the world could be key to revolutionising cancer prevention and care, according to a leading cancer expert from Queen’s University Belfast.
New research has found that a process initiated in white blood cells known as neutrophils may lead to worse outcomes for some patients with chronic obstructive pulmonary disease (COPD). The discovery may help identify patients at higher risk for COPD progression, who might also show little benefit from standard treatments.
Colon cancer is one of the most common forms of cancer in Germany. Prof. Dr. med. Sebastian Zeißig, group leader at the DFG Research Center for Regenerative Therapies Dresden (CRTD) - Cluster of Excellence at the TU Dresden and physician at the Department of Medicine I, University Hospital Carl Gustav Carus Dresden, has now shown a decisive role of gut bacteria in the regulation of intestinal…
The fates of immune cells can be decided at the initial division of a cell. Researchers at St. Jude Children’s Research Hospital have discovered that the production of daughter cells with different roles in the immune system is driven by the lopsided distribution of the signaling protein c-Myc. Nudging c-Myc in one direction or the other could make vaccines more effective or advance…
Imaging research is one step closer to giving clinicians a way to do high-resolution scans of malignant cells in order to diagnose cancer and help identify useful therapies. If this technology were to prove successful in clinical studies, it might change how anatomic pathologists and radiologists diagnose and treat cancer.
Scientists have many tools at their disposal for looking at preserved tissue under a microscope in incredible detail, or peering into the living body at lower resolution. What they haven't had is a way to do both: create a three-dimensional real-time image of individual cells or even molecules in a living animal.
Head and neck cancer patients may no longer have to undergo invasive post-treatment surgery to remove remaining cancer cells, as research shows that innovative scanning-led surveillance can help identify the need for, and guidance of, neck dissection. The study from the Universities of Birmingham and Warwick and University Hospitals Coventry and Warwickshire used advanced imaging to identify…
A research team headed by scientists at the Institute of Neuroimmunology and the Institute for Multiple Sclerosis Research (IMSF), University Medical Center Göttingen (UMG), has gained new insights into the immune function of cerebrospinal fluid (CSF). They used real-time microscopy to film the lively trafficking of immune cells between the CSF and the nervous tissue. Here the meninges play the…
Johns Hopkins scientists report they have developed an antibody against a specific cellular gateway that suppresses lung tumor cell growth and breast cancer metastasis in transplanted tumor experiments in mice, according to a new study published in the February issue of Nature Communications.
When there is an accident or a house fire, we call the police or the fire services. A control room quickly coordinates emergency operations. The cells in our bodies also have helpers in a crisis; the heat-shock proteins. These are triggered in response to cellular stress, such as high temperature, UV radiation or cancer. Heat-shock proteins help other proteins maintain their functional structure…
