August 29, 2024 by University of Southampton Scientists are on the verge of a cancer breakthrough after working out how the body’s immune system targets cells devastated by the disease. A new study has discovered that our natural killer cells, from the immune system which protect against disease and infections, instinctively recognize and attack a...
News Release 13-Aug-2024 Peer-Reviewed PublicationUniversity of Copenhagen – The Faculty of Health and Medical Sciences The study, published in the journal Cell, marks a step forward in the field of epigenetics and its impact on health and disease. Epigenetics, the study of how genes are turned on or off without changing the DNA itself, is...

DOI: 10.1038/s41586-024-07527-5Interactions between two key structures within cells help establish the front-to-back “polarity” that is essential to cell migration, according to a new study by...
By Paul McClure Researchers have added an active Rac2 protein to macrophages, causing them to cannibalize other immune cells Depositphotos Following a trail of evidence that started with a study of fruit flies nearly 25 years ago, researchers have found adding a hyperactive form of the protein Rac2 to macrophages, immune cells that eat pathogens, causes...
By Paul McClure Researchers have fitted “backpacks” to inflammatory cells to treat traumatic brain injury DepositphotosBy fitting microparticle ‘backpacks’ to important inflammatory cells called macrophages, researchers significantly reduced lesion size and inflammation caused by traumatic brain injury. Working with biology rather than against it, this novel approach has the potential to be an effective treatment for...
by European Synchrotron Radiation Facility The structure of the ACAD9-ECSIT_CTER complex (ECSIT in red). An international team of researchers, led by the ESRF, have elucidated the structure of the ACAD9-ECSIT_CTER complex, by using cryo-EM techniques. This complex is important in the correct functioning of the energy-producing machinery in mitochondria. Credit: ESRF/M. Soler López. Credit: ESRF/M. Soler...
by Cedars-Sinai Medical Center Credit: CC0 Public Domain A new Cedars-Sinai study might have cracked the mystery surrounding the cause of a specific type of back pain. Almost 40% of the adult population experiences low back pain due to degenerating disks in the spine, but medical science hasn’t understood exactly why the disks become painful. In...
