Abstract
OBJECTIVE: The aim of this review is to speculate the pre-clinical and clinical evidences indicating the association between butyrate-synthesizing firmicutes and development and progression of type 2 diabetes mellitus. METHODOLOGY: Literature was searched using 'Google Scholar' and 'PubMed' to find out most relevant articles for the scope of this review. Information was also gathered from authentic sources such as the World Health Organisation and the International Diabetes Federation. RESULTS: Evidences suggest that an abnormal perturbation in the gut microbiome characterized by subsided levels of butyrate-producing bacteria may gradually result in the progression of type-2 diabetes; however, the explicit mechanisms underlying and implicating the role of specific butyrate-producing microbes remain unclear. CONCLUSIONS: This review explicitly summarizes the role of butyrate-synthesizing firmicutes known to be reduced in the subjects with type-2 diabetes mellitus in host metabolic health and contemplates the putative and reported mechanisms underlying its implication in the pathophysiology of type-2 diabetes mellitus.
