A study found that in type 2 diabetes, misfolded proteins accumulate in mitochondria of pancreatic beta cells, impairing their function. The protein LONP1, responsible for clearing damaged proteins, is reduced in diabetic cells, leading to cell death. Restoring LONP1 in mice improved cell health and glucose regulation, suggesting a potential new therapeutic target for the disease.
Researchers have developed sugar-coated nanomaterials that can trap misfolded amyloid beta proteins, potentially preventing the formation of toxic plaques associated with Alzheimer's disease, offering a promising early intervention approach. Further studies are needed to assess their effectiveness in humans.
Scientists suggest that misfolded proteins, similar to prions, could potentially make dementia transmissible under rare circumstances involving medical procedures. Studies have shown that the sticky clumps of amyloid beta protein found in the brains of Alzheimer's patients may behave like prions and spread to other individuals. Concerns have been raised about the potential transmission of Alzheimer's proteins during neurosurgery or tissue transplants. While the evidence is not yet conclusive, better sterilization techniques may be needed for surgical tools to prevent the transmission of misfolded proteins associated with dementia.
Researchers are exploring the "gut-first" hypothesis, which suggests that Parkinson's disease may originate in the gastrointestinal tract. Misfolded proteins, found excessively in the brains of Parkinson's patients, accumulate in the nerves of the gut wall and ascend to the brain, causing pathological changes. Evidence linking Parkinson's to the gut includes the prevalence of constipation as a symptom, the increased risk of Parkinson's in patients with inflammatory bowel disease, and the presence of misfolded proteins in the stomach wall of Parkinson's patients. Understanding the origins of Parkinson's could lead to early detection and treatment options.

Researchers are investigating the "gut-first" hypothesis, which suggests that Parkinson's disease may originate in the gastrointestinal tract. Abnormal proteins, known as misfolded proteins, accumulate in the nerves of the gut wall and then ascend to the brain, causing the pathological changes associated with Parkinson's. Gut problems, such as constipation and inflammatory bowel disease, have been identified as risk factors for the disease. Autopsy studies have confirmed the presence of misfolded proteins in the gut of Parkinson's patients, and experiments in mice have shown that these proteins can travel from the gut to the brain. Understanding the origins of Parkinson's could lead to early detection and treatment options.
