Exposure to Agent Orange damages brain tissue in ways similar to Alzheimer's disease
February 15, 2024
Agent Orange, an herbicide used during the Vietnam War, is a known toxin with wide-ranging health effects. Even though Agent Orange has not been used for decades, there is increasing interest in its effects on the brain health of aging veterans. A new study reveals the mechanisms by which Agent Oran...

Gargling away the 'bad' bacteria in type 2 diabetes
February 14, 2024
Researchers have found that gargling with an antiseptic mouthwash can reduce so-called 'bad' bacteria in the mouths of patients with type 2 diabetes. Notably, this reduction in bacteria was accompanied by improved blood-sugar control in some patients. Given that the oral diseases caused by these bac...

Are stressed-out brain cells the root cause of neurodegenerative disease?
February 13, 2024
Many neurodegenerative diseases, such as dementia, are characterized by the abnormal aggregation of proteins inside cells, and treatments are being developed to break them up. But new research suggests that for some diseases, the aggregates are not directly killing cells. Aggregates prevent a protei...

Protein modifications key influencers in neurodegenerative diseases
February 12, 2024
Exploring the post-translational modifications of a key protein in Parkinson's disease, researchers uncover potential pathways for future therapies in neurodegenerative diseases in general.
Language barriers could contribute to higher aggression in people with dementia
February 9, 2024
Immigrants living with dementia were more likely to present with agitation and aggression compared with their non-immigrant counterparts, a new study has found.
Protein accumulation on fat droplets implicated in late-onset Alzheimer's disease
February 9, 2024
In an effort five years in the making, researchers describe the interplay between fats and proteins in brain cells and how their dysfunction contributes to the development of late-onset Alzheimer's disease.
Analysis of biological networks helps explain the complexity of multiple sclerosis
February 8, 2024
An international study has used a computational biology tool that, by analyzing a multitude of biological data from multiple sclerosis patients ranging from genetic information to the whole organism, reveals the relationship between elements of different biological scales and improves our knowledge ...
