Solid-State nanopores unravel twisted DNA mystery

Cancer thrives when mutated cells undergo frequent division. Most anti-cancer drugs work by inserting themselves in between the DNA base pairs that encode our genetic information. This process is known as intercalation, and it can result in subtle changes to the DNA molecule’s geometric shape or tertiary structure. These structural changes interfere with the DNA’s transcription and a cell’s…

Researchers Find Herpes Strain in the Nervous System

There are a couple strains of herpes so common that researchers estimate 90% of the human population have them. These strains, human herpes 6 and human herpes 7, usually do not cause severe symptoms when people acquire them. But researchers know that under certain circumstances, dormant herpes viruses in the body can unexpectedly come roaring back and cause complications not typically associated…

Testosterone clue to male heart deaths

As men appear to have higher risk of cardiovascular disease (CVD) than women of a similar age – with vascular calcification a strong predictor of mortality and morbidity from CVD – a team from the University of Edinburgh hopes that exploration of a link between gender and calcification could help unlock the pathway to new therapies. The researchers have been looking at whether sex hormones…

New Biomarker for cancer immunotherapy?

The Ligand PD-L1 is one of the most important targets for cancer immunotherapy with checkpoint inhibitors. But not all tumors have sufficient quantities of PD-L1 ligands on their surface. Scientists from the German Cancer Consortium (DKTK) have now shown that different types of cancer possess different quantities of PD-L1-Gen copies. Genetic analysis of the PD-L1 gene may in the future help to…

Immune system controls social interaction

In a startling discovery that raises fundamental questions about human behavior, researchers at the University of Virginia School of Medicine have determined that the immune system directly affects – and even controls – creatures’ social behavior, such as their desire to interact with others. So could immune system problems contribute to an inability to have normal social interactions? The…

How the brain is organized

The age of exploration has long passed, but there is at least one area still largely uncharted: the human brain. Now, a detailed new map by researchers at Washington University School of Medicine in St. Louis lays out the landscape of the cerebral cortex – the outermost layer of the brain and the dominant structure involved in sensory perception and attention, as well as distinctly human…

Potential genetic trigger of autoimmune disease

Researchers at Hospital for Special Surgery (HSS) have uncovered a potential genetic trigger of systemic autoimmune disease. The study, the culmination of more than 10 years of research, discovered virus-like elements within the human genome linked to the development of two autoimmune diseases: lupus and Sjogren's syndrome.

Natural killer cells have a memory

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…

Promising treatment prospects for invasive breast cancer

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…

Research suggests new contributor to heart disease

Medical professionals have long known that the buildup of plaque in arteries can cause them to narrow and harden, potentially leading to a whole host of health problems — including heart attack, heart disease and stroke. While high blood pressure and artery stiffness are often associated with plaque buildup, new research from engineers at Washington University in St. Louis shows they are not…

Gene therapy against brain cancer

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…

New neurodevelopmental syndrome identified

A multicenter research team led by Columbia University Medical Center (CUMC) has discovered a new neurodevelopmental syndrome and the genetic mutations that cause it. The discovery is an important step toward creating targeted therapies for individuals with this syndrome, which causes severe developmental delays, abnormal muscle tone, seizures, and eye complications.

Last resort antibiotic under treat

Data presented at the European Congress of Clinical Microbiology and Infectious Diseases diseases has highlighted how a recently-discovered mechanism could mean one of the last-resort antibiotics is under threat. Evidence put before ECCMID suggested the genetic mechanism allowing bacteria to develop and transfer resistance to colistin has been present in several countries around the world –…

Computer program uncovers hidden genomic alterations

Cancer is rarely the result of a single mutation in a single gene. Rather, tumors arise from the complex interplay between any number of mutually exclusive abnormal changes in the genome, the combinations of which can be unique to each individual patient. To better characterize the functional context of genomic variations in cancer, researchers at University of California San Diego School of…

Benefits from The Cancer Genome Atlas

Last year, scientists at the University of California San Francisco (UCSF) revealed that by measuring the proportion of both immune and cancerous cells in tumours, or ‘tumour purity,’ clinicians could more precisely predict the success of certain precision therapies. A key aspect of the discovery was access to over 10,000 samples constituting 21 different cancers.

Why is the immune system unable to combat HIV?

An international research group with essential participation of the Paul-Ehrlich-Institut, has identified NLRX1, a cellular factor of the human cell that is indispensable to the replication of Human Immunodeficiency Virus (HIV-1). This factor plays a key role in attenuating the innate immune system towards HIV-1. Until now, the significance of NLRX1 for the replication of HIV-1 and the…

How can two types of immune cells arise from one?

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…
