Hepatocyte PLAGL2 deficiency alleviates MASH through MYD88-licensed inactivation of inflammasome
Duan et al. systematically delineate the spatiotemporal dynamics and key regulators of pyroptosis during MASLD progression. Hepatocyte-specific Plagl2 deletion alleviates MASH by suppressing MYD88-mediated inflammasome activation and restoring metabolic homeostasis. Pyroptosis-driven IL-1β release promotes macrophage differentiation into a phagocytosis-enhanced, JAK/STAT-activated, NASH-associated phenotype.
Tinnitus Is Somehow Connected to a Crucial Bodily Function
Those who have never endured the relentless ringing of tinnitus can only dream of the torment. In fact, a bad dream may be the closest some get to experiencing anything like it.
The subjective sound, which can also be a hissing, buzzing, or clicking, is heard by no one else, and it may be present constantly, or may come and go.
Neuroscientists at the University of Oxford now suspect that sleep and tinnitus are closely intertwined in the brain.
Brain immune cells may help build Alzheimer’s plaques
A new study led by researchers from VIB and KU Leuven shows that immune cells called microglia can actively promote the formation of plaques in Alzheimer’s disease, challenging the long-standing view that these cells serve only as defenders against plaque buildup. The findings were recently published in the Proceedings of the National Academy of Sciences.
“Most studies suggest that microglia are there to clean up the brain and remove the amyloid plaques. What we discovered is that actually they’re part of the problem. They generate plaques,” says Prof. Joost Schymkowitz, co-senior author of the study at the VIB-KU Leuven Center for Neuroscience. “It was thought that plaques aggregate by themselves. And it seems that the microglia, by trying to deal with the problem, amplify it.”
Alzheimer’s disease affects nearly 55 million people worldwide and is characterized by the accumulation of toxic protein aggregates in the brain known as amyloid plaques. These plaques are associated with neuronal death and progressive dementia. The brain’s microglia have been hailed as protectors against plaque accumulation in the disease, being the focus of several therapies. Nonetheless, the study shows how microglia are active producers of amyloid plaques in the earlier stages of the disease, reconsidering the therapeutic paradigm for Alzheimer’s.
Movies reconstructed purely from mouse brain activity
Scientists have successfully reconstructed videos purely from the brain activity of mice, showing what the mice were seeing, in a new study led by University College London (UCL) researchers. The findings, published in eLife, could help shed light on the intricate workings of how the brain processes visual information and open new avenues for exploring how different species perceive the world.
Over recent years, there has been a growing interest in understanding exactly how the human brain interprets signals from the eye. Images and movies have been played to people in fMRI machines and researchers around the world have tried to decode the brain’s representations of visual information on a pixel level.
