It is possible for the non-motor symptoms (NMS) of Parkinson's disease (PD), which include constipation, sleep difficulties, and olfactory impairments, to appear up to 20 years before the motor symptoms of the disease. There is a growing body of research that suggests the pathology of Parkinson's disease may begin in the gastrointestinal tract and progress to the brain. Numerous studies provide credence to the idea that the microbiota in one's gut communicates with one's brain in Parkinson's disease (PD) via way of the immune system, a certain amino acid metabolism, and the neurological system. Through what has become known as the "gut microbiota-brain axis" (GMBA), the gut microbiota is thought to play an important part in the modulation of several neurochemical pathways.In the process of mediating the crosstalk between the gut microbiota and the physiology of the host, many of the metabolites produced by the gut microbiota, such as fatty acids, amino acids, and bile acids, carry signaling activities. In Parkinson's disease (PD), the quantity of amino acids and species-specific alterations of amino acids, such as glutamate and tryptophan, may interfere with the signaling transmission between nerve cells and disrupt the normal operation of the basal ganglia. Certain amino acids and the receptors that bind to them are being looked at as new possible targets for the treatment of PD. The purpose of the current investigation was to compile and analyze all of the evidence that is currently available on the gut microbiota-derived amino acid metabolic changes that are related with PD.

Letters to Editor
Given that CMBR Journal's policy in accepting articles will be strict and will do its best to ensure that in addition to having the highest quality published articles, the published articles should have the least similarity (maximum 18%). Also, all the figures and tables in the article must be original and the copyright permission of images must be prepared by authors. However, some articles may have flaws and have passed the journal filter, which dear authors may find fault with. Therefore, the editor of the journal asks the authors, if they see an error in the published articles of the journal, to email the article information along with the documents to the journal office.
CMBR Journal welcomes letters to the editor ([email protected]) for the post-publication discussions and corrections which allows debate post publication on its site, through the Letters to Editor. Critical letters can be sent to the journal editor as soon as the article is online. Following points are to be considering before sending the letters (comments) to the editor.
 Letters that include statements of statistics, facts, research, or theories should include appropriate references, although more than three are discouraged.
 Letters that are personal attacks on an author rather than thoughtful criticism of the author’s ideas will not be considered for publication.
 There is no limit to the number of words in a letter.
 Letter writers should include a statement at the beginning of the letter stating that it is being submitted either for publication or not.
 Anonymous letters will not be considered.
 Letter writers must include Name, Email Address, Affiliation, mobile phone number, and Comments
 Letters will be answered as soon as possible
