Glutamate system, amyloid ß peptides and tau protein: functional interrelationships and relevance to Alzheimer disease pathology.
Alzheimer disease is the most prevalent form of dementia globally and is characterized premortem by a gradual memory loss and deterioration of higher cognitive functions and postmortem by neuritic plaques containing amyloid ß peptide and neurofibrillary tangles containing phospho-tau protein. Glutamate is the most abundant neurotransmitter in the brain and is essential to memory formation throu...
متن کاملBrain Functional Connectivity Changes During Learning of Time Discrimination
The human brain is a complex system consist of connected nerve cells that adapts with and learn from the environment by changing its regional activities. Synchrony between these regional activities called functional network changes during the life, and with learning of new skills. Time perception and interval discrimination are among the most necessary skills for the human being to perceive mot...
متن کاملmiR‐132 loss de‐represses ITPKB and aggravates amyloid and TAU pathology in Alzheimer's brain
microRNA-132 (miR-132) is involved in prosurvival, anti-inflammatory and memory-promoting functions in the nervous system and has been found consistently downregulated in Alzheimer's disease (AD). Whether and how miR-132 deficiency impacts AD pathology remains, however, unaddressed. We show here that miR-132 loss exacerbates both amyloid and TAU pathology via inositol 1,4,5-trisphosphate 3-kina...
متن کاملWidespread Tau and Amyloid-Beta Pathology Many Years After a Single Traumatic Brain Injury in Humans
While a history of a single traumatic brain injury (TBI) is associated with the later development of syndromes of cognitive impairment such as Alzheimer’s disease, the long-term pathology evolving after single TBI is poorly understood. However, a progressive tauopathy, chronic traumatic encephalopathy, is described in selected cohorts with a history of repetitive concussive/mild head injury. He...
متن کاملIncreased midlife triglycerides predict brain β-amyloid and tau pathology 20 years later
OBJECTIVE To evaluate the effect of midlife lipid levels on Alzheimer brain pathology 20 years later in cognitively normal elderly individuals. METHODS This is a longitudinal cohort study of 318 cognitively normal individuals with data on fasting lipid levels at midlife (mean age 54 years). Presence of β-amyloid (Aβ) and tau pathologies 20 years later (mean age 73 years) were detected by quan...
