The phosphorylation of eIF2alpha, which decreases protein synthesis, was previously found at elevated levels in both humans diagnosed with Alzheimer's and in Alzheimer's Disease (AD) model mice.

In the Cell Reports study, the authors hypothesized that if they could decrease expression of this subunit, they could improve cognitive function of AS model mice.

Here, they found both increased levels of phosphorylated eIF2alpha in the hippocampus of both AD patients and the AD model mice.

However, other AS model mice had no memory of the platform location.

Moreover, this restoration also improved the model mice's synaptic function, diminished cognitive abnormalities, and normalized the structure of dendrites.

Here, the AD model mice lacking PERK were able to successfully maneuver through the mazes at rates achieved by normal mice.

By contrast, the other AD model mice lagged significantly in performing these tasks.

To explore this question, the researchers examined the neurological impact of two enzymes that phosphorylate eIF2alpha, kinases termed PERK and GCN2, in different populations of AD model mice — all of which expressed genetic mutations akin to those carried by humans with AD.

They examined behaviors of the following types of mice: normal mice, AS model mice, mice that had reduced levels of the Na / K - ATPase, and AS model mice in which expression of the subunit of Na / K - ATPase was reduced.

A previous study by Klann and his colleagues pointed to a potential cause for the condition — overexpression of a subunit of a protein termed Na / K - ATPase in AS model mice.

Delivery of rosuvastatin to ACH model mice (second from left) caused noticeable lengthening in bone compared to ACH model mice that received a vehicle (left).

In recent years, researchers have found that both humans with Alzheimer's Disease and AD model mice have relatively high levels of eIF2alpha phosphorylation.

These were: AD model mice; AD model mice that lacked PERK; and AD model mice that lacked GCN2.

«I was shocked at the profound effect phosphorylation had on the Huntington's model mice,» said first author Ian Kratter, MD, PhD, a former graduate student at Gladstone and the University of California, San Francisco.

A very large number of changes have been discovered in HD model mice and then subsequently observed in human HD patients, suggesting the mice are useful research tools, even if they don't really have Huntington's disease.

«I was shocked at the profound effect phosphorylation had on the Huntington's model mice,» said first author Ian Kratter, MD, PhD, a former graduate student at Gladstone and the University of California, San Francisco (UCSF).

What we'd like to understand is whether HD model mice have symptoms that resemble human depression.

Another behavior that scientists have observed in Huntington's disease model mice is that they aren't as motivated as normal mice to drink sweet water.

Excitingly, the in vitro expansion of MuSC cultures in the presence of PFI - 2 increased the yield and maintained the self - renewal capacity of MuSCs, and following transplantation into injured tibialis anterior muscles of muscular dystrophy model mice, boosted MuSC engraftment and overall therapeutic efficacy.

The lack of 5D12 binding in synaptic zones may limit its therapeutic effect, as appeared to be the case in LBD - model mice (vide infra).

At minimum, these two antibodies were clearly sufficiently powerful as to completely obviate the behavioral deficits exhibited by untreated PD - model mice (Figure 8).

Typically, MS - model mice experience severe motor problems, eventually leading to paralysis, but when they were given the drug the mice behaved perfectly normally.

We therefore suggest that the presence of the mutated transgenes (AβPP and PS1), which are per se the basis for the genetic form of Alzheimer's disease in humans, directly interferes with gut function as shown here for the disease model mice.

Both the patients and AD model mice were significantly impaired in terms of the distance traveled and the time it took for them to locate the hidden object.

To learn more, Tsai and Boyden first examined gamma waves in the hippocampi of Alzheimer's disease — model mice.

Compared with those of control animals, the hippocampi of the model mice had fewer gamma waves during sharp - wave ripples, but gamma waves during theta waves were unaffected.

Next, the researchers optogenetically stimulated hippocampal neurons to produce gamma waves in Alzheimer's disease — model mice that had transgenically received both a light - responsive ion channel and a fluorescent label in their hippocampal neurons.

Abstract: We previously reported that neuroinflammation contributes to the amnesia of AβPPswe / PSEN1dE9 Alzheimer's disease model mice fed a high - fat diet to induce type - 2 diabetes (T2DM - AD mice), but the underlying mechanism for the memory decline remained unclear.
