Inhibiting amyloid beta (1-42) peptide-induced mitochondrial dysfunction prevents the degradation of synaptic proteins in the entorhinal cortex

Author(s): Olajide OJ; La Rue C; Bergdahl A; Chapman CA;

Increasing evidence suggests that mitochondrial dysfunction and aberrant release of mitochondrial reactive oxygen species (ROS) play crucial roles in early synaptic perturbations and neuropathology that drive memory deficits in Alzheimer's disease (AD). ...

Ovariectomy reduces cholinergic modulation of excitatory synaptic transmission in the rat entorhinal cortex

Author(s): Batallán Burrowes AA; Olajide OJ; Iasenza IA; Shams WM; Carter F; Chapman CA;

Estrogens are thought to contribute to cognitive function in part by promoting the function of basal forebrain cholinergic neurons that project to the hippocampus and cortical regions including the entorhinal cortex. Reductions in estrogens may alter cognit ...

G protein-coupled estrogen receptor-1 enhances excitatory synaptic responses in the entorhinal cortex

Author(s): Batallán Burrowes AA; Sundarakrishnan A; Bouhour C; Chapman CA;

Activation of estrogen receptors is thought to modulate cognitive function in the hippocampus, prefrontal cortex, and striatum by affecting both excitatory and inhibitory synaptic transmission. The entorhinal cortex is a major source of cortical sensory and ...

Amyloid-β (1-42) peptide induces rapid NMDA receptor-dependent alterations at glutamatergic synapses in the entorhinal cortex

Author(s): Olajide OJ; Chapman CA;

The hippocampus and entorhinal cortex (EC) accumulate amyloid beta peptides (Aß) that promote neuropathology in Alzheimer's disease, but the early effects of Aß on excitatory synaptic transmission in the EC have not been well characterized. To assess th ...

Molecular mechanisms of neurodegeneration in the entorhinal cortex that underlie its selective vulnerability during the pathogenesis of Alzheimer's disease.

Author(s): Olajide OJ, Suvanto ME, Chapman CA

The entorhinal cortex (EC) is a vital component of the medial temporal lobe, and its contributions to cognitive processes and memory formation are supported through its extensive interconnections with the hippocampal formation. During the pathogenesis of Al ...
