Inflammasome – Gut microflora link to Metabolic syndrome; A case for metagenomics


Metabolic syndrome so far is attributed to the deregulation of the metabolic processes leading to increase triglycerides, fat, insulin resistance etc. and thereby leading to diabetes mellitus, coronary heart disease and hypertension. Inflammation is also one of the key factors that can cause an onset of metabolic syndrome.

Recently, a new article in Cell Research (a Nature publication) puts a new perspective on the role of gut micro biota as a causative effect in the process of inflammatory response in the liver (http://www.nature.com/cr/journal/vaop/ncurrent/full/cr201255a.html)

The article highlights certain interesting points and hypothesizes that defective inflammasome signaling in the gastro-intestinal tract allows colitogenic microbes to prosper in the colon, and subsequently trigger harmful inflammatory signaling pathways in systemic organs when the gastro-intestinal barrier is breached. The fact that defective inflammasome signalling can skew the gut micro biota towards colitogenic species of the Prevotellaceae family and the candidate phylum TM7 is not only interesting but opens a new dimension on the role of intestinal “niche” environment in regulating the microbiota species and thereby controlling different aspects of well being of humans (though the research highlighted above is in mice).

Role of gut microbes in maintaining robust immune system or even mental health have been reported earlier. In this era of genomics, it is therefore imperative that we use metagenomics to study gut microflora to understand the intestinal “niche” microenvironment. This would help in designing better targeted antibiotics for therapeutical intervention and thereby possible prevention of many of today’s lifestyle diseases!
