The postsynaptic density: there is more than meets the eye [PDF]

open access: yesFrontiers in Synaptic Neuroscience, 2016
The postsynaptic density (PSD), apparent in electron micrographs as a dense lamina just beneath the postsynaptic membrane, includes a deeper layer, the pallium, containing a scaffold of Shank and Homer proteins.

The postsynaptic density [PDF]

open access: yesCurrent Biology, 2009
What is the postsynaptic density (PSD)? Seen by electron microscopy (EM) as an electron-dense thickening of the postsynaptic membrane of excitatory synapses, the PSD contains a high concentration of structural and signaling proteins connected physically and functionally to postsynaptic glutamate receptors and transsynaptic adhesion molecules.

PROTEINS OF THE POSTSYNAPTIC DENSITY [PDF]

open access: yesThe Journal of Cell Biology, 1974
An analysis was made of the protein composition of a fraction of postsynaptic densities (PSDs) prepared from rat brain. Protein makes up 90% of the material in the PSD fraction. Two major polypeptide fractions are present, based on sodium dodecyl sulfate polyacrylamide gel electrophoresis. The major polypeptide fraction has a molecular weight of 53,000,

Postsynaptic density antigens: preparation and characterization of an antiserum against postsynaptic densities [PDF]

open access: yesThe Journal of Cell Biology, 1981
Long-term immunization of rabbits with postsynaptic densities (PSD) from bovine brain produced an antiserum specific for PSD as judged by binding to subcellular fractions and immunohistochemical location at the light and electron microscope levels. (a) The major antigens of bovine PSD preparations were three polypeptides of molecular weight 95,000 (PSD-

Lateral organization of the postsynaptic density [PDF]

open access: yesMolecular and Cellular Neuroscience, 2011
Fast excitatory synaptic transmission is mediated by AMPA-type glutamate receptors (AMPARs). It is widely accepted that the number of AMPARs in the postsynaptic density (PSD) critically determines the efficiency of synaptic transmission, but an unappreciated aspect of synapse organization is the lateral positioning of AMPARs within the PSD, that is ...

IRSp53 accumulates at the postsynaptic density under excitatory conditions. [PDF]

open access: yesPLoS ONE, 2017
IRSp53 (BAIAP2) is an abundant protein at the postsynaptic density (PSD) that binds to major PSD scaffolds, PSD-95 and Shanks, as well as to F-actin.

Differential synaptic mechanism underlying the neuronal modulation of prefrontal cortex, amygdala, and hippocampus in response to chronic postsurgical pain with or without cognitive deficits in rats

open access: yesFrontiers in Molecular Neuroscience, 2022
Chronic Postsurgical Pain (CPSP) is well recognized to impair cognition, particularly memory. Mounting evidence suggests anatomic and mechanistic overlap between pain and cognition on several levels.

Enlightening the Postsynaptic Density [PDF]

open access: yesNeuron, 1997
Research on the PSD touches many branches of neuroscience, and I regret that many relevant studies could not be cited for lack of space. I thank Drs. Nancy Desmond, Lucas Pozzo-Miller, Dennis Landis, James Gurd, and Philip Gordon-Weaks for provision of photographs of the PSD, Dr. R. MacKinnon for PDZ domain structure coordinates, and Drs.

Organization of the core structure of the postsynaptic density [PDF]

open access: yesProceedings of the National Academy of Sciences, 2008
Much is known about the composition and function of the postsynaptic density (PSD), but less is known about its molecular organization. We use EM tomography to delineate the organization of PSDs at glutamatergic synapses in rat hippocampal cultures. The core of the PSD is dominated by vertically oriented filaments, and ImmunoGold labeling shows that ...
