Therapy Seen to Restore Brain’s Ability to Clear Itself of Amyloid Plaques in Early Study

Therapy Seen to Restore Brain’s Ability to Clear Itself of Amyloid Plaques in Early Study
Researchers working in a mice reported that an experimental drug, NTRX-07, may treat Alzheimer's by targeting a potential cause — it was seen to ease brain inflammation in the animals by restoring the brain's ability to remove clumps of the beta-amyloid protein that is a hallmark of the disease. The excessive accumulation of the beta-amyloid protein in neurons promotes the onset of inflammatory processes in the brain, causing nerve cell damage and loss, and is thought responsible for such symptoms as cognitive deficits, memory loss and dementia. "This drug may reduce inflammation in the brain, which is linked to Alzheimer's disease," Mohamed Naguib, MD, lead author of the study presented at the recent Anesthesiology 2016  meeting in Chicago, said in a press release. "NTRX-07 uses a different mechanism than many other Alzheimer's drugs currently available, as it targets the cause of the disease, not just the symptoms." Researchers initially found that NTRX-07 could improve a chronic pain condition, called neuropathic pain, which is associated with sustained neuroinflammation. The team then investigated whether NTRX-07 also could ease inflammation in Alzheimer’s disease. Using mice with Alzheimer’s-like neurodegeneration, researchers noted that the disease changes a type of immune cell present in the brain, called microglia. Thes
