Neurons5
Anti-PrP antibodies targeting epitopes in the C-terminal domain induce currents, and cause degeneration of dendrites on murine hippocampal neurons, effects that entirely dependent on the effector function of the N-terminus. (elifesciences.org)
In one, published December 28 last year, first author Sabrina Simoes and colleagues reported that neurons rely on vacuolar protein sorting ortholog 26b (VPS26b), a retromer component. (alzforum.org)
In the January 18 issue, Small, Beth Stevens at Boston Children's Hospital, and colleagues reported that knocking out a different retromer protein, VPS35, in hippocampal neurons in mice not only jammed neuronal endosome traffic but also caused microglia to assume shapes resembling those seen in AD. (alzforum.org)
Adding VPS35 back into the neurons restored both protein trafficking and microglial morphology. (alzforum.org)

Receptor5
This gene encodes a protein receptor that localizes phosphoglycoproteins within endosomes and at the cell periphery. (wikipedia.org)
This trafficking receptor for phosphoglycoproteins may play a role in neuroplasticity by modulating cell-cell interactions, intracellular adhesion, and protein binding at membrane surfaces. (wikipedia.org)
When they tried to induce LTD with a glycine blocker (glycine is an obligatory co-agonist for NMDAR), they could again induce LTD. Their working hypothesis is that glutamate binding to NMDAR is necessary for LTD, but not ion flow through the receptor. (trailofpapers.net)
Knocking it out in mice slowed glutamate receptor recycling and weakened synaptic transmission, but only in the transentorhinal cortex, hinting at why this region is so vulnerable to AD pathology in people. (alzforum.org)
Indeed, LTP weakened and glutamate receptor GluA1 expression was lower in TEC brain slices, while both were normal in the medial entorhinal cortex. (alzforum.org)
Kinase4
VEGF-induced pMF was attenuated by the MEK/ERK inhibitor U0126 [1,4-diamino-2,3-dicyano-1,4-bis( o -aminophenylmercapto)butadiene] and was abolished by the phosphotidinositol 3 kinase/Akt inhibitor LY294002 [2-(4-morpholinyl)-8-phenyl-1(4 H )-benzopyran-4-one hydrochloride], demonstrating that ERK mitogen-activated protein kinases and Akt are both required for full expression of VEGF-induced pMF. (jneurosci.org)

Furthermore, Western blot pulldowns showed that CNIH binds to GluA1, but not GluA2. (trailofpapers.net)
Thus it appears the CNIH selectively bind to GluA1. (trailofpapers.net)

Induce1
In the metallothioneins, MT3 is especially enriched while in the brain, Some MT3 zinc binding web sites are redox modulated, making it possible for MT3 to accept and release zinc in response to changes in oxidative standing, Mainly because MT3 can induce or minimize zinc toxicity based on context, it could improve or reduce brain damage, based on the specific state of MT3. (ilreceptor.com)

However, protein levels of components of cell membranes, vesicles and synapses, RNA modulation, and cellular structures (including tau and tubulin filaments) are markedly altered from the age of 75. (ibecbarcelona.eu)
Mechanical force modulates the conformation and function of individual proteins, and this underpins many mechanically driven cellular processes. (ibecbarcelona.eu)
These diseases are caused by refolding of the cellular prion protein (PrP C ) into an infectious isoform (PrP Sc ) that catalytically templates its abnormal conformation onto additional molecules of PrP C ( Prusiner, 1998 ). (elifesciences.org)
