Medical Xpress / Alzheimer's tipping point revealed as brain immune cells hit a key transition
Researchers from VIB, KU Leuven, the UK-DRI and Muna Therapeutics have uncovered a critical biological transition that may determine whether Alzheimer's disease pathology leads to dementia. Studying brain tissue from older ...
Medical Xpress / Newfound 'switchboard' helps brain form new memories without forgetting older ones
The brain may reuse some cells to store many different memories without mixing them up with or erasing older memories, a new study in mice suggests. Led by NYU Langone Health researchers, the study revealed that about 1 in ...
Medical Xpress / New drug cuts relapse risk by half in rare immune disorder trial
Stanford Medicine researchers and their colleagues found that a new drug, obexelimab, significantly reduces the risk of relapse in patients with IgG4-related disease, a rare chronic immune condition often misdiagnosed as ...
Medical Xpress / Brain circuit links memory to hearing, revealing how learned sounds guide behavior
Short-term memories are thought to be formed deep within the brain in structures such as the hippocampus, but little is known about how and where memory-related information is kept in the brain or the process of drawing on ...
Medical Xpress / Motherhood leaves lifelong brain marks via dopamine-linked epigenetic switch, mouse study suggests
Becoming a mother changes the brain not just temporarily, but for life. Pregnancy and the postpartum period trigger lasting changes in the maternal brain through the brain chemical dopamine, producing long-term benefits to ...
Medical Xpress / Alzheimer's gene map expands to 91 loci, revealing 16 previously unknown risk regions
An international collaboration of genetic researchers has identified more than 90 genetic regions associated with the risk of Alzheimer's disease and related dementias. The large-scale meta-analysis reveals new biological ...
Medical Xpress / How cells fight infection from the inside: Newly identified ADX pathway may broaden understanding of immunity
When thinking of the immune system, most people imagine white blood cells putting up a fight against invading germs in the bloodstream. But now, in research published in Molecular Cell, scientists detail a separate but equally ...
Medical Xpress / Prenatal Zika exposure may trigger vision, hearing and social changes despite seemingly healthy births
Infants exposed to the Zika virus during pregnancy may face hidden developmental challenges, even if they appear healthy at birth. A recent study at the University of Wisconsin-Madison highlights the need for better developmental ...
Medical Xpress / Immune barrier may explain why mRNA shots struggle to block nasal infection
A consistent biological barrier that stops the immune system from making the antibodies most needed to protect the nose and throat from respiratory viruses has been identified. The discovery, led by researchers from the University ...
Medical Xpress / After early pregnancy loss, 'what if' thinking affects 72% within first week
When a person goes through a traumatic experience, they often find themselves thinking that what happened could have been different or even avoided. This process, known as counterfactual thinking, is an automatic psychological ...
Medical Xpress / At least two weather patterns increase headaches, study suggests
Two specific weather patterns have been identified as capable of increasing the risk of headaches, thanks to physicians at the University of Cincinnati College of Medicine, along with researchers at the Icahn School of Medicine ...
Medical Xpress / Fear memories form differently in male and female brains, study finds
Women are twice as likely as men to develop post-traumatic stress disorder (PTSD)—and new research may offer a biological clue as to why. A Virginia Tech study found that the female brain forms fear memories using a molecular ...
