In experiments with a protein called Ephexin5 that appears to be elevated in the brain cells of Alzheimer's disease patients and mouse models of the disease, Johns Hopkins researchers say removing it prevents animals from developing Alzheimer's characteristic memory losses. In a report on the studies, published online March 27 in The Journal of Clinical Investigation, the researchers say the findings could eventually advance development of drugs that target Ephexin5 to prevent or treat symptoms of the disorder.

Some previous studies have shown that hormone therapy may increase the risk of the disease, while others have shown that it may reduce the risk. The new study was published in the February 15, 2017, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Calcium in the mitochondria -- the energy factory of cells -- may be one of the keys to understanding and treating Alzheimer's disease and dementia. Researchers at Temple University have now identified how an imbalance of calcium ions in the mitochondria may contribute to cell death and, specifically, neurodegeneration in brain cells during Alzheimer's and dementia. The findings could eventually point to new therapies for preventing or delaying these diseases. The team will present its work during the 61st Meeting of the Biophysical Society.
Currently, the predominant theory behind Alzheimer’s disease is the “amyloid hypothesis,” which states that abnormally increased levels of amyloid beta (Aβ) peptides outside of brain cells produce a variety of low molecular weight Aβ aggregates that are toxic to the nervous system. These Aβ aggregates interact directly with target cells and lead to cell death. During the Biophysical Society’s meeting, being held Feb. 11-15, 2017, Antonio De Maio will present his work hunting for the specific mechanisms behind Aβ-induced toxicity to cells, or cytoxicity.
Rutgers scientists say neurodegenerative diseases like Alzheimer’s and Parkinson’s may be linked to defective brain cells disposing toxic proteins that make neighboring cells sick. In a study published in Nature, Monica Driscoll, distinguished professor of molecular biology and biochemistry, School of Arts and Sciences, and her team, found that while healthy neurons should be able to sort out and rid brain cells of toxic proteins and damaged cell structures without causing problems, laboratory findings indicate that it does not always occur.

Leading neuroscientists have clarified the role of a controversial immune system protein in Alzheimer’s disease, showing it has opposing effects in early and late stages of the disease. Their discovery unites previous studies that left researchers conflicted and showed the protein both exacerbates and ameliorates disease symptoms. The updated model of disease progression, published in the Journal of Neuroscience, also highlights the need to align certain therapies with disease stages when treating the 1 in 9 Americans over 65 living with Alzheimer’s.

PHOENIX – Mayo Clinic researchers have found that engaging in mentally stimulating activities, even late in life, may protect against new-onset mild cognitive impairment, which is the intermediate stage between normal cognitive aging and dementia. The study found that cognitively normal people 70 or older who engaged in computer use, craft activities, social activities and playing games had a decreased risk of developing mild cognitive impairment. The results are published in the Jan. 30 edition of JAMA Neurology.

Scientists at Washington University School of Medicine in St. Louis have detailed the structure of a molecule that has been implicated in Alzheimer’s disease. Knowing the shape of the molecule — and how that shape may be disrupted by certain genetic mutations — can help in understanding how Alzheimer’s and other neurodegenerative diseases develop and how to prevent and treat them.
Tests that measure the sense of smell may soon become common in neurologists’ offices. Scientists have been finding increasing evidence that the sense of smell declines sharply in the early stages of Alzheimer’s, and now a new study from the Perelman School of Medicine at the University of Pennsylvania published today in the Journal of Alzheimer’s Disease confirms that administering a simple “sniff test” can enhance the accuracy of diagnosing this dreaded disease
