Tau is a protein which regulates microtubule stability and is heavily involved in axonal transport. This stability is dynamically controlled in part by over 40 phosphorylation sites across the tau protein which allows for binding and release from the microtubules. However, if abnormal hyperphosphorylation occurs, tau dissociates from the microtubules. Once released, the microtubules become unstable and the aberrant tau mislocalizes from the axon to the somatodendric compartment, where it aggregates. These aggregates are made of many pathological forms of tau including oligomeric species, paired helical filaments, and neurofibrillary tangles, all of which have associated toxicities. Tau pathology is a …

Implications Of Human Umbilical Cord Blood Cells: An Immunotherapeutic Strategy For Alzheimer's Disease, Donna Darlington

ABSTRACT
Alzheimer's disease (AD) is the most common progressive age related dementia and the fourth major cause of mortality in the elderly in the United States. AD is pathologically characterized by deposition of amyloid beta (Aβ) plaques in the brain parenchyma and neurofibrillary tangles (NFTs) within the neuronal soma. While pharmacological targets have been discovered, current strategies for the symptomatic or disease-modifying treatment of AD do not significantly slow or halt the underlying pathological progression of the disease. Consequently, more effective treatment is needed. One possibility for amelioration is using human umbilical cord blood cell (HUCBC) therapy. HUCBCs comprise a …

Ube3a Role In Synaptic Plasticity And Neurodevelopmental Disorders.The Lessons From Angelman Syndrome., Irina Filonova
USF Tampa Graduate Theses and Dissertations
Angelman Syndrome (AS) is a severe neurodevelopmental disorder that affects 1:12000 newborns. It is characterized by mental retardation, delayed major motor and cognitive milestones, seizures, absence of speech and excessive laughter. The majority of AS cases arise from deletions or mutations of UBE3A gene located on the chromosome 15q11-13. UBE3A codes for E3-ubiquitin ligase that target specific proteins for degradation. To date, a wide variety of Ube3a substrates has been identified. The accumulation of Ube3a-dependent proteins and their effect on the multitude of signal transduction pathways are` considered the main cause of the AS pathology. While the majority of research …
