Altered Proteins in the Aging Brain
We assessed the prevalence of common altered brain proteins in 296 cognitively unimpaired subjects ranging from age 50 to 102 years. The incidence and the stage of hyperphosphorylated-τ (HPτ), β-amyloid, α-synuclein (αS), and transactive response DNA (TDP) binding protein 43 (TDP43)-immunoreactivity (-IR) increased with age. HPτ-IR was observed in 98% of the subjects; the locus coeruleus was so...
متن کاملAltered synaptic dynamics during normal brain aging.
What is the neuroanatomical basis for the decline in brain function that occurs during normal aging? Previous postmortem studies have blamed it on a reduction in spine density, though results remain controversial and spine dynamics were not assessed. We used chronic in vivo two-photon imaging of dendritic spines and axonal boutons in somatosensory cortex for up to 1 year in thy1 GFP mice to tes...
متن کاملNeurogenesis in the aging brain
Neurogenesis, or the birth of new neural cells, was thought to occur only in the developing nervous system and a fixed neuronal population in the adult brain was believed to be necessary to maintain the functional stability of adult brain circuitry. However, recent studies have demonstrated that neurogenesis does indeed continue into and throughout adult life in discrete regions of the central ...
متن کاملCardiac dysfunction in aging conscious rats: altered cardiac cytoskeletal proteins as a potential mechanism.
The objective of this study was to test the hypothesis that the mechanism mediating left ventricular (LV) dysfunction in the aging rat heart involves, in part, changes in cardiac cytoskeletal components. Our results show that there were no significant differences in heart rate, LV pressure, or LV diameter between conscious, instrumented young [5.9 +/- 0.3 mo (n = 9)] and old rats [30.6 +/- 0.1 ...
متن کاملRecognition and characterization of Erythropoietin binding-proteins in the brain of mice
Objective(s): Erythropoietin (EPO), is a 34KDa glycoprotein hormone, which belongs to type 1 cytokine superfamily. EPO involves in erythrocyte maturation through inhibition of apoptosis in erythroid cells. Besides its main function, protective effects of EPO in heart and brain tissues have been reported. EPO has a critical role in development, growth, and homeostasis of brain. Furthermore EPO h...
