Immunizing transgenic PDAPP mice, which overexpress mutant APP and develop beta-amyloid deposition resembling plaques in Alzheimer's disease (AD), results in a decrease of amyloid burden when compared with non-treated transgenic animals. Immunization with amyloid-beta peptide has been initiated in a randomised pilot study in AD. Yet a minority of patients(More)
The state of development of the financial sector does not change monotonically over time. In particular, by most measures, countries were more financially developed in 1913 than in 1980 and only recently have they surpassed their 1913 levels. We propose an interest group theory of financial development where incumbents oppose financial development because(More)
Brain-derived neurotrophic factor (BDNF), and full-length and truncated tyrosin kinase B receptor (TrkB) protein expression were examined by Western blotting and immunohistochemistry in the frontal cortex and hippocampus of individuals affected by long-lasting severe Alzheimer disease (AD) and age-matched controls. Since preliminary processing studies in(More)
OBJECTIVE To investigate chaperone-mediated autophagy in the pathogenesis of Parkinson disease (PD). DESIGN Postmortem observational study. SETTING University Department of Clinical Neuroscience, Institute of Neurology, University College London. SUBJECTS Postmortem samples from 7 PD, 6 Alzheimer disease (AD), and 8 control brains. MAIN OUTCOME(More)
Most of the mammalian genome is transcribed. This generates a vast repertoire of transcripts that includes protein-coding messenger RNAs, long non-coding RNAs (lncRNAs) and repetitive sequences, such as SINEs (short interspersed nuclear elements). A large percentage of ncRNAs are nuclear-enriched with unknown function. Antisense lncRNAs may form(More)
Huntington disease (HD) is a neurodegenerative disorder that predominantly affects neurons of the forebrain. We have applied the Illumina massively parallel sequencing to deeply analyze the small RNA populations of two different forebrain areas, the frontal cortex (FC) and the striatum (ST) of healthy individuals and individuals with HD. More than 80% of(More)
Focal ischemia by middle cerebral artery occlusion (MCAO) results in necrosis at the infarct core and activation of complex signal pathways for cell death and cell survival in the penumbra. Recent studies have shown activation of the extrinsic and intrinsic pathways of caspase-mediated cell death, as well as activation of the caspase-independent signaling(More)
MicroRNAs (miRNAs) are post-transcriptional gene expression regulators, playing key roles in neuronal development, plasticity and disease. Parkinson's disease (PD) is the second most common neurodegenerative disorder, characterized by the presence of protein inclusions or Lewy bodies and a progressive loss of dopaminergic neurons in the midbrain. Here, we(More)
Although many age-related changes have been described in the nervous system of different species, few authors have specifically studied the topic. Knowledge of such changes is essential to veterinary pathologists, who must distinguish the lesions of specific pathologic processes from those arising as a result of normal aging. The brains of 20 old dogs,(More)
Frontotemporal lobar degeneration (FTLD) is the second most common cause of presenile dementia. The predominant neuropathology is FTLD with TAR DNA-binding protein (TDP-43) inclusions (FTLD-TDP). FTLD-TDP is frequently familial, resulting from mutations in GRN (which encodes progranulin). We assembled an international collaboration to identify(More)
