Furthermore, GSOs protected cells against GLU-induced apoptosis by reducing the expression of the mitochondrial apoptosis-associated Bcl-2 family effector proteins and protected cells from GLU-induced oxidative damage by increasing the nuclear translocation of Nrf2 and HO-1 expression.

Lewy bodies are abnormal deposits of a protein in the brain. (medlineplus.gov)

Multiple subtypes or forms are recognized based on presence or absence of TAU PROTEIN inclusions. (bvsalud.org)

Other nervous system microtubule-associated proteins (MAPs) may perform similar functions, as suggested by tau knockout mice that did not show abnormalities in brain development - possibly because of compensation in tau deficiency by other MAPs. (wikipedia.org)
In mice, while the reported tau knockout strains present without overt phenotype when young, when aged, they show some muscle weakness, hyperactivity, and impaired fear conditioning. (wikipedia.org)
However, neither spatial learning in mice, nor short-term memory (learning) in Drosophila seems to be affected by the absence of tau. (wikipedia.org)
In addition, tau knockout mice have abnormal sleep-wake cycle, with increased wakefulness periods and decreased non-rapid eye movements (NREM) sleep time. (wikipedia.org)
26S proteasomes from normal mice incubated with recombinant oligomers or fibrils also showed lower hydrolyzing capacity in the same assays, implicating tau as a proteotoxin. (genengnews.com)
And when we decreased the protein build-up, we saw behavioral improvement in these mice. (foxnews.com)
We demonstrated non-invasive whole-brain imaging of tau in P301L mice with vMSOT system using PBB5 at a previously unachieved ~ 115 μm spatial resolution. (springer.com)

The details of how proteins are moved around within a cell are being deciphered with high-powered microscopy combined with sophisticated techniques for labeling individual molecules, including fluorescent or "quantum dot" tags and antibodies tailored to adhere to a protein in a particular state of activation.

CTE, which can only be diagnosed postmortem, is a progressive neurodegenerative brain disorder that has been reported in athletes with multiple concussions or subconcussive injuries. (sciencedaily.com)

Tau is a negative regulator of mRNA translation in Drosophila, mouse, and human brains, through its binding to ribosomes, which results in impaired ribosomal function, reduction of protein synthesis and altered synaptic function. (wikipedia.org)

He also established the first mouse model of Tau pathology and proved the amyloid cascade hypothesis. (edu.au)
VCP is often involved in those cases where it finds proteins in an aggregate and pulls them apart," Edward Lee, MD, Ph.D., an assistant professor of Pathology and Laboratory Medicine in the Perelman School of Medicine at the University of Pennsylvania. (medicalxpress.com)
Images of neurodegenerative findings can be viewed online at Internet Pathology Laboratory, University of Utah, CNS Degenerative Diseases. (medscape.com)

Clogs, a recent study has shown, may occur when the toxic protein known as tau sticks to the proteasome. (genengnews.com)
We don't need to know what the toxic form of the protein is," Dr. Duff added. (genengnews.com)
Moussa compared nilotinib to a garbage disposal, in that it helps to eliminate the trash, or toxic proteins, from brain cells. (foxnews.com)

However, capturing early tau deposits in vivo is needed for a better understanding of the link with other pathological alterations in deep brain regions. (springer.com)

In addition to its microtubule-stabilizing function, Tau has also been found to recruit signaling proteins and to regulate microtubule-mediated axonal transport. (wikipedia.org)

However, performing an assay to detect tau protein on a nanoscale is a great challenge for early diagnosis of diseases. (bvsalud.org)
