The sisters with childhood Alzheimer's

Both Abby, three, and Belle, seven, have Niemann-Pick Type C1, a genetic disease where in time, children slowly regress until they can ’t walk, eat, and dementia will set in before age 10.

Because of their unique morphological and functional specialization, cells of this type are sensitive to the stress caused by accumulation of misfolded proteins or damaged organelles. Autophagy is the fundamental mechanism that ensures sequestration of cytosolic material and its subsequent degradation in lysosomes of eukaryotic cells, thereby provid...

This study underscores the importance of chronic stimulation in the modulation of sensorimotor integration and proprioception. The authors considered two possible mechanisms underlying SAI modulation by STN DBS. High-frequency DBS of the STN might normalize synchronization between basal ganglia structures, which might restore the ability of thalamocortical relay cells to respond to depolarizing inputs involved in sensorimotor integration (Brown et al., 2001; Rubin and Terman, 2004). Alternatively, STN DBS might have a direct effect on cortical structures through antidromic stimulation of the cortico-subthalamic pathway. I...

Hydroxypropyl-β-cyclodextrin formulated in nasal chitosan microspheres as candidate therapeutic agent in Alzheimer's disease. Curr Drug Deliv. 2017 Oct 19;: Authors: Rassu G, Gavini E, Carta A, Obinu A, Porcu EP, Giunchedi P Abstract Hydroxypropyl-β-cyclodextrin (HP-CD) is a hydroxyalkyl derivative of native β-cyclodextrin, cyclic oligosaccharide able to form inclusion complexes with many drugs and biomolecules [1]. Cyclodextrins have a possible neuroprotective effect due to their capability to extract and deplete cholesterol from cell membranes [1]. HP-CD is classified as an excipient ...

Abstract Trisomy 21 and the consequent extra copy of the amyloid precursor protein (APP) gene and increased beta-amyloid (Aβ) peptide production underlie the universal development of Alzheimer's disease (AD) pathology and high risk of AD dementia in people with Down syndrome (DS). Trisomy 21 and other forms of aneuploidy also arise among neurons and peripheral cells in both sporadic and familial AD and in mouse and cell models thereof, reinforcing the conclusion that AD and DS are two sides of the same coin. The demonstration that 90% of the neurodegeneration in AD can be attributed to the selective loss of a...
