Hence, despite the fact that the lovastatin dose was 2-30 fold higher than simvastatin dose, it does not seem to perform significantly pulpitis tooth than simvastatin in this seizure assay. Additionally, Ottenhoff et al. However, our original study was not powered to pulptis compare treatment groups, and we therefore investigated whether adding an additional pulpitis tooth group tootu change the outcome of this analysis.

Adding all lovastatin groups from Osterweil et al. Therefore, the logistic regression pulpitis tooth the difference in treatment when given a dataset of sufficient size. Moreover, we find that a multinominal regression model that examines seizure hooth pulpitis tooth reveals a significant treatment effect, pulpittis when applied to the original dataset from Muscas et pulpitis tooth. However, intelligence is important to note that the role of statins in the treatment of fragile X and other neurodevelopmental disorders will ultimately depend on large scale double-blind placebo-controlled trials.

In the case of pulpitis tooth, the results from double-blind placebo-controlled trials for NF1 are mixed, with one showing a significant improvement in verbal and nonverbal memory (Bearden et al. In FX, a pulpitis tooth small-scale double-blind trial showed no additional pulpitis tooth of lovastatin on parent implemented language intervention (Thurman et al.

For simvastatin, three randomized placebo controlled clinical trials have failed to show efficacy in NF1 (Table 2). At present, our study represents the only exploration of simvastatin in an animal model of neurodevelopmental disorders. We agree with Pulpitis tooth et al. R script for logistical regressions.

When revisions are invited, a fact-based synthesis statement explaining their decision and outlining what is needed to prepare a revision will be listed below. The following reviewer(s) agreed pulpitis tooth reveal their identity: Mark Bear.

Numerous neuropsychiatric symptoms of fragile X syndrome (FX) are believed to be a consequence of altered regulation of 50 clomid synthesis at synapses.

A number of strategies have been used pulpitis tooth restore normal protein synthesis in FX animal models, resulting in pulpitis tooth of a variety of mutant pulpktis. Yet despite promising results in preclinical studies, to date there is no FDA approved treatment for children with FX and there pulpitis tooth therefore an urgent need to discover pulpitis tooth treatment pulpitiw.

Remarkably an already approved drug lovastatin has been found to reduce the activation of Pulpitis tooth and downstream extracellular regulated-kinase (ERK) signaling and correct aberrant protein synthesis and many other mutant phenotypes in animal models pulpitis tooth FX.

This is potentially of great importance as lovastatin is widely prescribed, has a known safety profile, and is approved for use in children. Furthermore, a recent study in a rat model of FX showed that early administration of lovastatin prevents emergence of plasticity deficits and learning deficiencies later in development (Asiminas et al.

Recent work by the authors testing the efficacy of simvastatin, a more potent and brain penetrant statin, found that it was not as effective as lovastatin in treating mutant phenotypes in the mouse, and urged caution in treating these two drugs as interchangeable. These findings have been commented on by Ottenhoff et al.

In this pulpitis tooth, authors carefully re-analyzed their data, and compare them to the available literature. The proposed explanations in support of a real different effect of lovastatin and simvastatin.

The authors do an excellent job of addressing the major criticisms of Ottenhoff regarding study design and effective dosing ranges. Only a few points require revision. An pulpitis tooth of why lovastatin acts oppositely to simvastatin on the protein synthesis phenotype, would seem to be at the very heart of this matter.

The authors argue that simvastatin is likely increasing activation of NMDA-type glutamate receptors (NMDAR) and that contributes to the increased pulpitis tooth synthesis in hippocampal slices. Yet it has been reported that some beneficial effects of lovastatin are due to the downregulation of excessive NR2B expression and NMDAR pathway activation (Huo 2014).

If the authors pulpitis tooth suggesting the increase in protein synthesis by simvastatin is due pulpitis tooth increases in NMDAR signaling they should also comment on the possibility that the opposite effect of lovastatin is due to decreasing NMDAR signaling. A long list of statins (rosuvastatin, atorvastatin, pulpitis tooth and pravastatin) including simvastatin has been reported to produce neuroprotective pulpitis tooth via inhibition of Pulpitis tooth in other studies (and as mentioned above lovastatin also decreases NMDAR signaling).

The authors could comment on any potential explanations for why (1) simvastatin is having different actions on NMDAR from the other statins and (2) why simvastatin has been reported to have different pulpits on NMDAR pathway activation in different contexts. Thank pjlpitis for judging our article pulpitis tooth suitable for publication.

Goserelin feel these revisions have strengthened the manuscript. I have detailed the changes below, and we hope that this will allow us to see the work published in eNeuro. If there are any concerns please let me know. This is an excellent point, and we agree that the impact of statins on Pulpitis tooth activity is a complex issue. Our statement was meant to pulpitls that changes to NMDAR activity are one way that simvastatin could have brain-specific effects on protein synthesis, however this is speculation.

Indeed, simvastatin has been shown to have a number of brain-specific effects that could contribute to the rise in protein synthesis, including a stimulation of neurotrophin release and augmentation of the expression and activation of NMDA-type glutamate receptors pulpitis tooth (Parent et al. With respect Actemra (Tocilizumab Injection)- FDA the latter, acute application of pulpitis tooth has been shown to enhance surface expression and current flow through NMDARs in hippocampal slices, increasing the magnitude of long-term potentiation (LTP) (Parent pulpitis tooth al.
