Using subcloning and manipulations of culture conditions we have isolated from the mouse myogenic cell line C2 a variant cell line that we named inducible. Unlike the progenitor cells that are referred to as permissive, inducible myoblasts differentiate poorly in Dulbecco modified Eagle medium plus fetal calf serum (FCS) and require the presence of insulin(More)
The τ pathology found in Alzheimer disease (AD) is crucial in cognitive decline. Midlife development of obesity, a major risk factor of insulin resistance and type 2 diabetes, increases the risk of dementia and AD later in life. The impact of obesity on AD risk has been suggested to be related to central insulin resistance, secondary to peripheral insulin(More)
Tau pathology is encountered in many neurodegenerative disorders known as tauopathies, including Alzheimer's disease. Physical activity is a lifestyle factor affecting processes crucial for memory and synaptic plasticity. Whether long-term voluntary exercise has an impact on Tau pathology and its pathophysiological consequences is currently unknown. To(More)
While the spatiotemporal development of Tau pathology has been correlated with occurrence of cognitive deficits in Alzheimer's patients, mechanisms underlying these deficits remain unclear. Both brain-derived neurotrophic factor (BDNF) and its tyrosine kinase receptor TrkB play a critical role in hippocampus-dependent synaptic plasticity and memory. When(More)
An impairment of the mucosal glycoconjugates could be an important factor in the development of bladder disorders such as interstitial cystitis. However, very little definitive biochemical information is available on the glycoco-jugate components of the mammalian bladder mucosa. In this-study, the mucosa from metabolically radiolabeled rabbit bladder was(More)
Alzheimer's disease (AD) is a neurodegenerative disorder characterized by extracellular accumulation of amyloid deposits and intracellular neurofibrillary tangles (NFT) composed of hyperphosphorylated Tau proteins. Brain-derived neurotrophic factor (BDNF) is a neurotrophic factor playing a critical role in hippocampal synaptic plasticity and memory and(More)
BACKGROUND AND PURPOSE The ATP-gated P2X(7) receptor has been shown to play a role in several inflammatory processes, making it an attractive target for anti-inflammatory drug discovery. We have recently identified a novel set of cyclic imide compounds that inhibited P2X(7) receptor-mediated dye uptake in human macrophage THP-1 cells. In this study the(More)
The synthesis and pharmacological evaluation of a new series of potent P2X(7) receptor antagonists is disclosed. The compounds inhibit BzATP-mediated pore formation in THP-1 cells. The distribution of the P2X(7) receptor in inflammatory cells, most notably the macrophage, mast cell and lymphocyte, suggests that P2X(7) antagonists have a significant role to(More)
Tau pathology found in Alzheimer's disease (AD) is crucial in cognitive decline. Epidemiologic evidences support that habitual caffeine intake prevents memory decline during aging and reduces the risk to develop Alzheimer's disease. So far, experimental studies addressed the impact of caffeine in models mimicking the amyloid pathology of AD. However, in(More)
Tau is a central player in Alzheimer's disease (AD) and related Tauopathies, where it is found as aggregates in degenerating neurons. Abnormal post-translational modifications, such as truncation, are likely involved in the pathological process. A major step forward in understanding the role of Tau truncation would be to identify the precise cleavage sites(More)
