School scientists identify faulty molecular recycling as potential driver of Alzheimer ’s disease

School scientists recently uncovered how neurons normally recycle old proteins, and how this process goes awry in Alzheimer's disease, leading to the toxic building of protein fragments in the brain.

ConclusionsThe results demonstrate that even subtle changes in vessel morphology can be noninvasively quantified. This is of great interest for AD, but also to other models of neurodegenerative diseases involving macrovascular dysfunction.

In this study, our previously proposed persistent features and various traditional graph-theoretical measures are used to quantify the topological property of white matter (WM) network in 150 subjects with diffusion tensor imaging (DTI). We found significant differences in these measures among AD, MCI, and normal controls (NC) under different brain parcellation schemes. The decreased network integration and increased network segregation are presented in AD and MCI. Moreover, the persistent homology-based measures demonstrated stronger statistical capability and robustness than traditional graph-theoretic measures, suggesti...

Alzheimer's disease (AD) has an estimated prevalence of 50 million persons worldwide1 and an incidence of 10 million cases per year1-3, making it the most common form of dementia. While neuropsychiatric symptoms (NPS) are common in AD, apathy is particularly frequent, affecting up to 70% of patients4. Apathy has been broadly defined as a loss of interest in daily activities and diminished goal directed behavior in the absence of depression and other mood changes5 –7 . This NPS is associated with greater functional impairment, greater caregiver burden, increased risk of institutionalization, poorer quality of life, an...

ConclusionsMultiple signal pathways involve therapeutic mechanisms by which the transplantation of BMMSCs improves cognitive and behavioral deficits in AD models. Gene expression profile can be utilized to establish statistical regression model for the evaluation of therapeutic effect. The transplantation of autologous BMMSCs maybe a prospective therapy for patients with Alzheimer ’s disease.
