Talk:Glutamate receptor

message: Hi,
You guys have made a great start on updating this article.  I have a couple of suggestions:
* Citations. If you haven't seen this yet, please check out User:Diberri's Wikipedia template filling tool.  Given a PubMed ID, one can quickly produce a formatted citation that can be copied and pasted into a Wikipedia article.  This will save you an enormous amount of work and insures that the citations are displayed in a consistent manor.
* Introduction and conclusion sections are not normally included in Wikipedia articles.  I have taken the liberty of merging the introduction into the lead section.  The conclusion section should be integrated with the rest of the article.
* Organization.  It appears that the sections of this article were written independently and then merged together.  This is understable given the requirements of your course but the end result is that the article is not as cohesive as it should be.  The section entitled "Types" contains a list of the mGluR subtypes while "Genetics" contains a list of the iGluR subtypes.  These two sections should be merged.  The "Pathology" and "Current research" sections contain the same type of information and probably should be merged together.  The focus should be kept on the receptor and not research about the receptor.
Again, good work.  Cheers. Boghog (talk) 10:54, 31 October 2009 (UTC)

First, you should revaluate the organization of subtopics beneath main headings, particularly in the “Clinical significance” section.  It seems that the “Excitotoxicity” subtopic does not belong—make it its own heading, or, if appropriate, clarify its relevance to the clinical significance of glutamate receptors within the article.
In addition, I suggest you consider discussing in greater detail the role of glutamate receptors in EAE and Multiple Sclerosis pathogenesis under the “Potential therapeutic applications” section.  Drugs that interact with ionotropic glutamate receptors to suppress EAE have emerged over the last decade, and use of receptor antagonists to control EAE with the possibility of therapeutic application in MS has also been investigated.  You can find this information at:
* 
You list MS under “Neurogenerative diseases” (which should be changed to “Neurodegenerative diseases”)—perhaps consider combining the “Clinical Significance” and “Potential therapeutic applications” sections.

Hey guys I have a few things I suggest you include in your article. First, I think you should not only describe glutamate receptor function in neurons, but also describe their function in glial cells. Here are a couple articles I found on this subject:
*  and 
* 
Finally, it would be more informative to describe the NMDA receptor in more detail including serine/glycine coagonists, the antagonist binding sites (Zn site, Mg blocker, MK801/PCP binding site), and also NMDA’s role in silent synapses.

message: Hi, I found an article specifically discussing when the glutamate receptor was first cloned in 1989. Perhaps you may want to cite some of the implications of this research and some of the questions that were raised from the data. It may provide a better background as to where research is going and what is still left to be answered about the glutamate receptor.

message: Hi guys,
I think you all have done a great job, I just had a couple of suggestions/comments that might be helpful.  I would include some pictures/diagrams in your article; these figures will help the reader understand the content better.  I think our textbook has a couple of good ones.  I would also go into a little more detail about how AMPA and NMDA receptors work, especially how NMDA receptors rely on AMPA receptors to depolarize the cell.  In addition, I would also explain how Glutamate transport is affected by energy deficiency in your ischemia section.  
Great job!

message: Hi!
Overall, I think the article does a great job of providing some basic knowledge about glutamate receptors. I just had a little trouble with the organization of the topics. For example, the discussion of  ionotropic and metabotropic receptors in the "Function" section precedes the more detailed explanation in subsequent section. 
Also, you do a good job of talking about receptors in the PNS but I think a section of receptors in glial cells might be helpful. You might also be able to mention the link to oxidative stress. (cystine xCt transporter).

thread_title:  Comment 5  

message: Great job on the article and congrats on the Good Article nomination. I noticed that suggestions to gain GA status included a need for more information linking glutamate receptors to schizophrenia. I took the liberty of researching the topic a little further and found a very informative article published November 16, 2009 titled "Glutamatergic deficits and parvalbumin-containing inhibitory neurons in the prefrontal cortex in schizophrenia." It can be found through PubMed, http://www.ncbi.nlm.nih.gov/pubmed/19917116?itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum&ordinalpos=1. The article discusses how expression of mRNA for the NR2A subunit of the NMDA receptors was decreased in a subset of inhibitory interneurons in the cerebral cortex in schizophrenia and how this pathophysiology contributes to the disease. In terms of cleaning up the already existing sections of the article, I also agree with previous sections that the "Function" section can use some elaboration regarding the mechanism of both the AMPA and NMDA receptors. I understand that additional Wiki pages exist for these topics, but do feel that as the first section in your article, it is important to effectively explain how these receptors function, especially in terms of HOW this functioning leads to plasticity. Currently, you just mention that it does lead to plasticity. Otherwise, this is a very impressive article!

thread_title:  Comment 6 

message: First off, well written article, I found it overall easy to follow and I think it covered the subject very well. In the section labeled "Function" I noticed that your explanation included information regarding the binding of NMDA to NMDA receptors that, while correct, may be a little bit confusing when considering the article is covering the glutamate binding to these specific receptors. I think that you should make a point of stating that, while NMDA is the specific agonist for the receptor, the receptor is more important for its binding of glutamate in the CNS. Additionally, when you mention that the receptor causes an action potential it can be misleading. Perhaps it would be more clear if you said that the receptor opened as a result of the agonist binding, and the resulting ion flow, when combined with the flow of many receptors, leads to an excitation and perhaps an action potential. There is a mention in the article telling the reader "as mentioned in the pathology section" but I noticed there is no specific section in the article. Finally, you did a good job of mentioning glutamate receptors in the PNS, but when you talk about their role in diabetes it is merely hinted at. If there is more information, perhaps the role of glutamate receptors in diabetes would be a good topic to expand upon.

thread_title: Comment 7

message: In the table for types of glutamate receptors, metabotropic is misspelled as “imetabotropic”.
In the “Effects outside the central nervous system” section, the sentence describing immunohistochemistry should have the pronoun “them” replaced with “iGluRs” to clarify the sentence.
In the Clinical Significance section, under the Excitotoxicity subheading, it is mentioned that excitotoxicity can be induced, but the significance of this phenomenon is not stated.  Mentioning that neurodegenerative diseases, such as Alzeheimer’s and Parkinson’s may result will lead to a better transition for the next two subheadings.
Regarding the Ischemia subsection in Potential therapeutic applications, the role of calcium in relation to glutamate receptors and ischemia should be discussed.
In the seizures subsection, the sentence “Using rodent models, labs have found that the introduction of antagonists to these glutamate receptors help counteract the epileptic symptoms” should be reworked.  The mention of “labs” is inappropriate and should be rephrased.
Overall, the article is very informative and the use of tables helps to organize information.
