Previous reports have demonstrated that IL-1 is elevated in the Alzheimer's disease brain. We propose that beta-amyloid (A beta) in senile plaques triggers microglial interleukin-1(IL-1) release. Since microglia and monocytes have similar lineage and functions, the human monocyte cell line, THP-1, was used to determine whether A beta peptides can stimulate(More)
Trypsin digestion of retinal pigment epithelium is a technique that bares Bruch's membrane, to allow topographical examination by scanning electron microscopy. Twenty-five human eyes were examined. The zonula occludens of the pigment epithelium was clearly seen as a surface feature, but attachment plaques at the sides and base were not visible. The adhesion(More)

Extracellular concentrations of excitatory amino acids increase substantially within cerebral tissue beds exposed to ischaemic conditions. This leads to excessive stimulation of N-methyl-D-aspartate (NMDA) receptors, a major cerebral excitatory neurotransmitter receptor that likely plays a critical role in the propagation of ischaemic injury in neurons.(More)
