Activation of kainate receptors causes Co2+ influx into neurons, type-2 astrocytes, and O-2A progenitor cells. Agonist-activated Co2+ uptake can be performed using cultured cells or fresh tissue slices. Based on the pattern of response to kainate, glutamate, and quisqualate, three functionally different kainate-activated ion channels (K1, K2, and K3) can be(More)
Passive immunization with an antibody directed against the N terminus of amyloid beta (Abeta) has recently been reported to exacerbate cerebral amyloid angiopathy (CAA)-related microhemorrhage in a transgenic animal model. Although the mechanism responsible for the deleterious interaction is unclear, a direct binding event may be required. We characterized(More)
Nerve growth factor (NGF) has been demonstrated to facilitate neurite outgrowth, rescue neurons from injury, and prevent programmed cell death in neurons. However, the therapeutic potential of NGF is limited by metabolic instability and poor CNS penetration. These limitations might be circumvented by identifying compounds which increase endogenous(More)
Activated caspase-3 is considered an important enzyme in the cell death pathway. To study the specific role of caspase-3 activation in neuronal cells, we generated a stable tetracycline-regulated SK-N-MC neuroblastoma cell line, which expressed a highly efficient self-activating chimeric caspase-3, consisting of the caspase-1 prodomain fused to the(More)
The β-secretase enzyme, β-site amyloid precursor protein-cleaving enzyme 1 (BACE1), cleaves amyloid precursor protein (APP) in the first step in β-amyloid (Aβ) peptide production. Thus, BACE1 is a key target for candidate disease-modifying treatment of Alzheimer’s disease. In a previous exploratory Aβ biomarker study, we found that BACE1 inhibitor treatment(More)
