Reduced brain-derived neurotrophic factor (BDNF) signaling is considered as a pathogenic event in early Alzheimer's disease (AD), but the influence of apathy and apolipoprotein E ε4 allele (APOE4) on serum BDNF values was not previously investigated in AD. We evaluated serum BDNF levels in AD, amnestic mild cognitive impairment (MCI), and control subjects.(More)
Tumor necrosis factor-alpha (TNF-alpha) and insulin-like growth factor-I (IGF-I) have been involved in the pathogenesis of Alzheimer's disease (AD) as neurotoxic and survival factors, respectively. Recent experimental studies suggest that the signalling pathways of TNF-alpha and IGF-I are functionally interrelated. In order to investigate the possible(More)
We document the presence of subpopulations of neurons within the rat central nervous system that are labelled with a new Congo red staining technique. These neurons (CR neurons) show shrunken somata, and smaller and darker nuclei than Congo red-negative cells (non-CR cells). With the Bielschowsky and the cresyl violet Nissl staining methods, two comparable(More)
About 80% of functional genes in the human genome are expressed in the brain and over 1,200 different genes have been associated with the pathogenesis of CNS disorders and dementia. Pharmacogenetic studies of psychotropic drug response have focused on determining the relationship between variations in specific candidate genes and the positive and adverse(More)
Traumatic brain injury (TBI) is a leading cause of death and disability for which there is currently no effective drug therapy available. Because drugs targeting a single TBI pathological pathway have failed to show clinical efficacy to date, pleiotropic agents with effects on multiple mechanisms of secondary brain damage could represent an effective option(More)
