Scientists know that Down syndrome is caused by an extra copy of chromosome 21, but they haven’t yet understood how the extra chromosome causes many of the brain and health problems associated with Down syndrome. One idea is that alterations of overall protein levels in the brain may affect learning and memory. Now, researchers have used a mouse model of Down syndrome called Ts65Dn as well as brain tissue and cells from people with Down syndrome to begin to ascertain whether blocking a particular cellular pathway in brain cells improves learning and memory.
Scientists have determined that La Crosse virus (LACV), which can cause inflammation of the brain in children, affects brain cells differently depending on their developmental stage. After infecting cerebral organoids with LACV, the researchers observed that the virus was more likely to kill neurons and that the immune response to the virus was weaker in the organoids than in neural stem cells. The investigators then repeated the experiment, but this time treating the cerebral organoids after infecting them. The therapy successfully protected neurons from virus-induced death.
Publishing giant Elsevier has signed its first open-access deal with a U.S. institution, Carnegie Mellon University (CMU) in Pittsburgh, Pennsylvania. The arrangement will allow CMU scholars to publish articles in any Elsevier journal on an immediately free-to-read basis. CMU researchers will also continue to have access to paywalled Elsevier articles, which previous contracts covered with subscription fees. CMU did not disclose the cost of the arrangement, which has been a sticking point in Elsevier’s open-access negotiations with other research institutions.
A lifelong swimmer leapt into deep water near his lakeside home and was horrified to find himself completely unable to swim. He had recently received an electronic brain implant to control tremors and other symptoms of Parkinson’s disease, and somehow the signals from the device had knocked out his ability to coordinate his arms and legs for swimming. He was one of nine patients, all good swimmers despite having Parkinson’s, who had the same strange, dangerous side effect from deep brain stimulators. When three of the patients turned off the stimulators, they could immediately swim again.
Giving a shot of ketamine to heavy drinkers after reactivating their drinking-related memories led to a rapid decrease in urges to drink and a prolonged decrease in alcohol intake over nine months, according to the study published in Nature Communications. The researchers were seeking to upend the maladaptive reward memories that are central to drug and alcohol addiction. They unexpectedly removed an anticipated reward—a pint of beer—and then prevented the restabilization and storage of the reward memory using ketamine. Researchers caution that further research is needed to optimize the treatment method and determine who it could benefit.
Fibromyalgia (FMS) is a chronic disorder marked by whole body aches and pains and extreme daytime fatigue. Symptoms can come and go, and they often worsen over time. Many people with FMS experience symptoms so severe that it interferes with their daily lives. Experts believe that FMS symptoms result from dysfunction of the central nervous system (CNS), but because the CNS is involved in seemingly endless processes in our bodies, fibromyalgia can feel and look different to everyone. This article presents the findings of a number of studies examining the causes of fibromyalgia as well as some suggestions for potential relief.
