Increased brain injury markers in response to asymptomatic high-accelerated head impacts

Researchers from the University of Michigan found that serum levels of two biomarkers of traumatic brain injury, tau and ubiquitin C-terminal hydrolase L1, are elevated following high-acceleration head impacts, even when there is no clinical diagnosis of concussion. Their complete findings are reported today in the Journal of Neurosurgery, in the article “Elevated markers of

Researchers find combination can enhance ipilimumab immunotherapy: Anti-CTLA-4 treatment triggers immune-suppressing EZH2 on T cells; clinical trial open

Using a targeted therapy to block a protein that suppresses T cell activity could improve cancer treatment with immune checkpoint inhibitors, researchers at The University of Texas MD Anderson Cancer Center report today in the Journal of Clinical Investigation. The team showed that EZH2 is elevated in immune T cells in patients after treatment with

Psychedelic drugs promote neural plasticity in rats and flies

Psychedelic drugs may have mind-altering powers in the physical sense, too. A new study, published June 12 in the journal Cell Reports, found psychedelics, specifically DOI, DMT, and LSD, can change brain cells in rats and flies, making neurons more likely to branch out and connect with one another. The work supports the theory that

Waves move across the human brain to support memory: Columbia Engineers discover a new fundamental feature of brain oscillations: These traveling waves reflect patterns of neuronal activity that move across the cortex and are important for memory and cognition

The coordination of neural activity across widespread brain networks is essential for human cognition. Researchers have long assumed that oscillations in the brain, commonly measured for research purposes, brain-computer interfacing, and clinical tests, were stationary signals that occurred independently at separate brain regions. Biomedical engineers at Columbia Engineering have discovered a new fundamental feature of

Inexpensive detector is like ‘Velcro®’ for cancer cells

Researchers have developed a new type of sensor that acts like Velcro® for prostate cancer cells, sticking them to a modified frosted glass slide, like those used in science classes, so that they can be identified from blood samples. The low-cost method, reported in ACS Applied Materials & Interfaces, could help doctors better diagnose and

Bioengineers identify safer way to make rugby tackles: Their recommendations should reduce the risk of players suffering concussions and other head injuries

Bioengineers have compiled a set of recommendations that could significantly reduce concussions and other head injuries in rugby union, having assessed how head impacts and movement vary based on the position on the body where tackles are made. The bioengineers discovered that the risks are not precisely the same for the two groups, as tacklers

Childhood cancer: The four survival strategies of tumor cells

Cancer cells in children tend to develop by following four main trajectories — and two of them are linked to relapse of the disease, research led by Lund University in Sweden shows. The four strategies can occur simultaneously in a single tumour, according to the study that is now published in Nature Genetics. The researchers

CLL patient goes into remission thanks to single CAR T cell: Case study provides clues that could help improve response rates

The doctors who have spent years studying the case call it “a series of fortunate events.” What began as a remarkable response to chimeric antigen receptor (CAR) T cell therapy is now providing evidence about the human genome and immune response that could help turn gene therapy non-responders into responders. Researchers at the University of

‘Second brain’ neurons keep colon moving: Brain in the gut coordinates activity of millions of neurons to propel waste through digestive system

Millions of neurons in the gastrointestinal tract coordinate their activity to generate the muscle contractions that propel waste through the last leg of the digestive system, according to a study of isolated mouse colons published in JNeurosci. The newly identified neuronal firing pattern may represent an early feature preserved through the evolution of nervous systems.

Cancer cells co-opt pain-sensing ‘wasabi receptor’ to survive oxidative stress: Antioxidants and the TRPA1 channel protein complement each other to increase tumor survival

Anyone who’s taken a bite of a sandwich with too much spicy mustard or a piece of sushi with too much wasabi can attest to the tear-inducing sensation these condiments can cause. These loud warnings to the nervous system of exposure to potentially harmful chemicals are triggered by TRPA1, a calcium channel protein sometimes referred

Embryonic mammary gland stem cells identified: Researchers define for the first time the mechanisms responsible for the mammary gland development

Publication in Nature Cell Biology: researchers at the Université libre de Bruxelles, ULB define for the first time the mechanisms responsible for the mammary gland development. The mammary gland is the tissue that produces the milk during lactation, allowing the survival of young mammalian offspring. The mammary gland is composed of two main lineages: the

Immune cell provides cradle for mammary stem cells: Study shows how macrophages and mammary stem cells talk to each other through chemical signaling.

A new study finds that one of the toughest characters in the immune system, the macrophage, has a nurturing side, at least when it comes to guarding the developing breast. The study published online this week in the journal Science found that macrophages play an important role in maintaining the mammary gland’s stem cell niche,

Learning music or speaking another language leads to more efficient brains: Whether you learn to play a musical instrument or speak another language, you’re training your brain to be more efficient, suggests a Baycrest study

Whether you learn to play a musical instrument or speak another language, you’re training your brain to be more efficient, suggests a Baycrest study. Researchers found that musicians and people who are bilingual utilized fewer brain resources when completing a working memory task, according to recently published findings in the journal, Annals of the New

Cellular valve structure opens up potential novel therapies

Human cells are enclosed by membranes and are in osmotic equilibrium with their environment. If the concentration of solute molecules (osmolarity) in the fluid surrounding the cells decreases, cells start to swell; in extreme cases, this can result in the cells bursting. To avoid this, cells activate volume-regulated chloride channels (VRACs) of the LRRC8 protein

National trial: EEG brain tests help patients overcome depression

Imagine millions of depressed Americans getting their brain activity measured and undergoing blood tests to determine which antidepressant would work best. Imagine some of them receiving “brain training” or magnetic stimulation to make their brains more amenable to those treatments. A national research trial initiated by UT Southwestern in 2012 is generating the first set

EPO protects preemies’ brains by modifying genes essential for generating new brain cells: Modified genes are essential for neurogenesis and responding to environmental stressors

Erythropoietin (EPO) helps to protect and repair vulnerable brains though it remains a mystery how the anemia drug does so. Genetic analyses conducted by a multi-institutional research team finds that EPO may work its neuroprotective magic by modifying genes essential for regulating growth and development of nervous tissue as well as genes that respond to
