A new open access paper takes a look at tryptophan and the role that it plays in the dysfunction of the immune system in the context of the age-related changes that occur in the microbiome [1]. The microbiome The gut microbiome is a complex ecosystem of bacteria, archaea, eukarya, and viruses that live inside of…

A new study suggests that harmful changes to the population and diversity of our gut bacteria may occur when we are as young as our mid 30s, which can have serious implications for health and longevity. The microbiome The gut microbiome is a complex and ever-changing ecosystem populated by a myriad of archaea, eukarya, viruses,…

Researcher Dr. Michael Lustgarten has recently published a compact and very readable review that focuses on the role of the gut microbiome and its influence on skeletal muscle mass. The gut microbiome The microbiome describes a varied community of bacteria, archaea, eukarya, and viruses that inhabit our gut. The four bacterial phyla of Firmicutes, Bacteroidetes,…

The relationship between health and the microorganisms living in the gut has increasingly reached the spotlight in the last few years, and a new study led by researchers at Nanyang Technological University, Singapore (NTU Singapore) sheds more light on the gut microbiome and how it can influence aging. The gut microbiome The gut microbiome is…

A new paper explores adjusting the types of bacteria in the gut as a potential way to improve health in older people. The microbiome The gut microbiome is a fascinating and diverse ecosystem filled with a myriad of bacteria, archaea, protists, fungi, and viruses that interact with each other and our bodies in diverse and…

A role for the gut microbiome on the health and functioning of many tissues, including the brain, liver, kidney, and adiposity, has been widely reported in the literature. Interestingly, 2019 might be the year that the role of the gut microbiome on skeletal muscle (i.e. the gut-muscle axis) comes into greater focus. The influence of…

Researchers at the University of Helsinki have shown why the regenerative capacity of the cells lining the intestines declines with age and that targeting a particular enzyme can restore the regenerative potential of this tissue. Notum blocks the Wnt pathway During normal function, the cells of the intestinal epithelium, a single cell layer that forms…

The role that the gut microbiome plays in aging is increasingly being appreciated in the research world as more evidence arrives to support it. A new publication reviews the various supporting evidence and takes a look at the gut microbiome in the context of poor diets and how they may facilitate the progression of dysbiosis…

A new study has outlined the age-related changes of the gut microbiome, showing a correlation between the microbiome’s composition and overall health. The gut microbiome The microbiome describes a varied community of bacteria, archaea, eukarya, and viruses that inhabit our gut. The four bacterial phyla of Firmicutes, Bacteroidetes, Proteobacteria, and Actinobacteria comprise 98% of the…
