In the April 27th issue of JAMA Neurology, researchers released new data that suggests 18F-flortaucipir positron emission topography (PET) can help clinicians diagnose late-stage Alzheimer’s Disease (AD). The results of the large autopsy validation study revealed that the PET tau tracers can identify the underlying presence of neurofibrillary tangles (NFTs) at the B3 level (Braak stages V …
Repetitive Negative Thinking Linked to Alzheimer’s Disease
According to a study published in Alzheimer’s & Dementia, cognitive decline and the deposition of harmful proteins in the brain linked to Alzheimer’s Disease (AD) may be related to the practice of repetitive negative thinking (RNT). RNT, also called perseverative thinking, consists of rumination on the past and worry about the future. The term RNT …
Research Breakthrough: Antibodies for the Quantification of Amyloid Beta Oligomers in Alzheimer’s Disease
Researchers have designed an antibody that can identify toxic particles that destroy healthy brain cells. A collaboration of scientists from the University of Cambridge, University College London, and Lund University published their findings in an article titled “Rational design of a conformation-specific antibody for the quantification of amyloid beta oligomers” in Proceedings of the National …
Proteomic Analysis Studies in Alzheimer’s Disease and Cerebral Atherosclerosis Research
RNA sequencing studies of thousands of post mortem human brain samples have generated massive datasets for use in medical research. These studies implicate many different biological functions in Alzheimer’s Disease (AD) — but how do these findings translate to proteins, the most important building blocks in the brain? Two studies from scientists at Emory University …
Protein Shapes in Alzheimer’s Disease Research
Proteins — large molecules made up of amino acids — do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs. A confluence of circumstances leads the proteins to twist, unfold, and refold the way they are meant to for regular functioning — but …
Early Detection of Alzheimer’s Disease Through exRNA Biomarkers
Alzheimer’s Disease (AD), a progressive neurodegenerative disease, is estimated to affect around 50 million people worldwide. AD is most prevalent in North America and Western Europe, and it is the top cause of disabilities in people 65 and older in the United States. Identifying early warning signs has proved elusive, although researchers are working hard …
QPS Neuropharmacology and Paracelsus Medical University (PMU) Announce Cooperation on a Parkinson’s Disease Research and Development Project
Parkinson’s disease (PD) is one of the most common neurodegenerative diseases, and the Parkinson’s Foundation estimates that 1.2 million people in the United States will suffer from this chronic, progressive condition by 2030. Although a cure does not currently exist, new therapies have the potential to meaningfully impact the lives of people with Parkinson’s disease. QPS …
Solanezumab Study Misses the Mark for the Fourth Time
Last month, American pharmaceutical company Eli Lilly ended its fourth study investigating the effectiveness of solanezumab, a potential drug therapy for people with mild cognitive impairment caused by Alzheimer’s disease. Researchers designed the eight-year trial, known as DIAN-TU, to test the therapy’s safety, tolerability, biomarker, and cognitive efficacy on participants with a genetic mutation that causes …
5xFAD Mice Cleared of Tau and Amyloid Proteins Through Light and Sound
The 5xFAD mouse is a popular rodent model in the preclinical Alzheimer’s disease research community. Recently, research performed on 5xFAD mice benefited Shanghai-based company Green Valley’s drug candidate Oligomannate, which was approved for clinical use in mild to moderate Alzheimer’s disease in China. In addition, 5xFAD mice were an integral part of another potentially important study in Alzheimer’s …
5xFAD Mice Offer Hope for Alzheimer’s Disease Research
Recently, the Shanghai-based company Green Valley announced approval of their drug candidate Oligomannate for clinical use in mild to moderate Alzheimer’s disease (AD) in China. This news made a big splash because nearly two decades have passed since the last approval of an Alzheimer’s drug. The successful approval of this drug was partially based on …
