Parkinson's Disease News and Research

RSS

Parkinson's disease is a brain disorder. It occurs when certain nerve cells (neurons) in a part of the brain called the substantia nigra die or become impaired. When approximately 80 percent of neurons are damaged, the symptoms of Parkinson's disease appear. Parkinson's disease affects 1 in 100 people over the age of 60, with the average age of onset being 60 years. The risk of developing Parkinson's disease increases with age. In the United States, it is estimated that 60,000 new cases of Parkinson's disease are diagnosed each year, with 1.5 million Americans currently living with the disease.

Study Reveals Mechanisms Behind Swallowing in Detail

Sensory cells in the vagus nerve can detect and locate food in the esophagus. Their signals help transport the food onward to the stomach. Signal failure leads to swallowing disorders, say a team led by Carmen Birchmeier at the Max Delbrück Center.

Researchers Elucidate the Exact Mechanism of Cell Death

New Insights into the Final Step of Cell Death

Every day, millions of cells die in our body. Other than generally assumed, cells do not simply burst at the end of their lives but rather, a specific protein serves as a breaking point for cell membrane rupture. Researchers at the University of Basel have now been able to elucidate the exact mechanism at the atomic level. They have published their results in Nature.

Study Sheds Light on How Foxp2 Gene Controls the Ability to Produce Speech

Mutations of a gene called Foxp2 have been linked to a type of speech disorder called apraxia that makes it difficult to produce sequences of sound. A new study from MIT and National Yang Ming Chiao Tung University sheds light on how this gene controls the ability to produce speech.

Study Uncovers a Protein-Protein Interaction Related to Parkinson's Disease

In a study published in Nature Communications, a team led by Krembil Brain Institute Senior Scientists, Drs. Lorraine Kalia and Suneil Kalia, and University of Toronto (U of T) Professor, Dr. Philip M. Kim, identified a protein-protein interaction that contributes to Parkinson's disease.

Engineered Sustainable, Patient-Specific NPCs Could Help Treat Neurodegenerative Diseases

Progressive loss of neurons is the underlying cause for a diverse spectrum of severe diseases called neurodegenerative diseases, which include Parkinson's disease, amyotrophic lateral sclerosis (ALS) and retinitis pigmentosa.

New Peptide Blocks a Hyperactive Brain Enzyme Involved in Neurodegeneration

MIT neuroscientists have found a way to reverse neurodegeneration and other symptoms of Alzheimer's disease by interfering with an enzyme that is typically overactive in the brains of Alzheimer's patients.

Pesticide residues in water test kit for sustainable and safe agriculture

Farmers in Thailand still largely use chemical herbicides, especially paraquat and atrazine, to control weeds on their farms. According to research by the Office of Agricultural Economics, in 2019, Thailand imported almost 10 million kilograms of paraquat and close to 3.5 million kilograms of atrazine.

Synthetic biosensor could lead to better understanding of cell biology

A synthetic biosensor that mimics properties found in cell membranes and provides an electronic readout of activity could lead to a better understanding of cell biology, development of new drugs, and the creation of sensory organs on a chip capable of detecting chemicals, similar to how noses and tongues work.

Researchers reveal key developmental difference between the brains of modern humans and Neanderthals

AZoLifesciences speaks to Dr. Anneline Pinson and Prof. Dr. Wieland B. Huttner from The Max Planck Institute of Molecular Cell Biology and Genetics about their latest research which found a greater neuron production in the frontal lobe during brain development in modern humans than Neanderthals, due to the change of a single amino acid in the protein TKTL1.

Researchers discover 15 genetic 'hotspots' that speed up or slow down brain aging

Researchers from a USC-led consortium have discovered 15 "hotspots" in the genome that either speed up brain aging or slow it down -; a finding that could provide new drug targets to resist Alzheimer's disease and other degenerative brain disorders, as well as developmental delays.
