by Karolinska Institutet Credit: Unsplash/CC0 Public Domain Researchers at Karolinska Institutet, University of Oslo, and Oslo University Hospital have developed a new kind of immunotherapy for leukemia. The results of a study published in Nature Biotechnology show that the therapy kills cancer cells from patients with acute lymphoblastic leukemia. The researchers now want to conduct...
Seizures and memory problems in epilepsy may have a common cause
Damage to a part of the brain that regulates hyperactivity can contribute to both memory problems and seizures in the most common form of epilepsy, according to research at the University of Wisconsin–Madison. The study, published recently in the Journal of Neuroscience, may lead to earlier diagnosis of epilepsy and possibly new ways to treat...
Senolytic Treatment Minimizes the Contribution of Excess Fat Tissue to Insulin Resistance in Mice
Senescent cells accumulate with age throughout the body, and contribute directly to the onset and progression of a wide range of age-related conditions. While never present in large numbers in comparison to normal somatic cells, senescent cells are metabolically active, secreting signals that provoke chronic inflammation, altered cell behavior, and numerous forms of tissue dysfunction....

Oops! You did it again. New test predicts if impulsivity is pathological
by Yasmin Anwar, University of California – Berkeley Figure 1. The emotional stop-signal task (ESST) instructs participants to rapidly indicate the valence of serially presented images by keypress, except on trials with an auditory stop-signal, when participants are asked to inhibit their emotional reaction and accompanying behavioral response. If participants are unable to inhibit an...
Venom makes a beeline through blood brain barrier, delivering medication
by Gina Wadas, Johns Hopkins University Credit: Pixabay/CC0 Public Domain The blood-brain barrier is an essential and meticulous protector of the human body. This highly selective gatekeeper of interlocking endothelial cells forms tight junctions, shielding vulnerable brains cells from toxins in the bloodstream. However, this also means that the BBB blocks many compounds from entering...
Three-dimensional X-ray image spotlights neurodegenerative disease
by Göttingen University The image shows neuronal cell nuclei of the dentus gyratus (yellow) and associated blood vessels (red). By varying the magnification of the X-ray optics, one can “zoom in” on the densely packed band of neurons (in the red oval) and also resolve the substructure of the cell nucleus (blue oval). The study...
