Category : Gut Brain Axis

Recent advances in research have described the importance of gut microbiota in influencing interactions between the central and the enteric nervous systems. These brain-gut interactions appear to be bidirectional by means of neural, endocrine, immune, and humoral signals. Most of the data have been acquired using rodents (mice or rats) and pigs.   Evidence of microbiota-mental health interactions comes from…

When Michael Gershon called the digestive system "the second brain" in his 1999 book, it was because scientists were beginning to realize that the gut and the brain in humans were engaged in constant conversation. Emeran Mayer, a leading researcher in the field of the gut-brain axis, affirms that this connection has been known for years. "Gut-brain communication is firmly…

Many living organisms have circadian rhythms—biological processes that oscillate in a pattern following a roughly 24-hour cycle. In humans, researchers have observed the rhythmic expression of 'clock genes', resulting in molecular changes in multiple body tissues; the entire process is coordinated by 'pacemakers' such as the brain's hypothalamic suprachiasmatic nucleus. In addition to regulating physiological processes, the host's circadian clock…

A recent study, led by Dr. Peng Xie from the Chongqing Medical University in China, has demonstrated that intestinal ‘dysbiosis’ may have a causal role in the development of depressive-like behaviours in mice through altering host metabolism.   It has been previously described that the gut microbiota may be an environmental factor that can modulate brain physiology through the microbiota-gut-brain…

Prof. Dr. Paul Enck, Director of Research, Dept. of Psychosomatic Medicine and Psychotherapy, University Hospital Tübingen, Germany. His main interests are gut functions in health and disease, including functional and inflammatory bowel disorders, the role of the gut microbiota, regulation of eating and food intake and its disorders, of nausea, vomiting and motion sickness, and the psychophysiology and neurobiology of the placebo response, with specific emphasis on age and gender contributions. He has published more than 170 original data paper in scientific, peer-reviewed journals, and more than 250 book chapters and review articles. He is board member/treasurer of the European Society of Neurogastroenterology and Motility and of the German Society of Neurogastroenterology and Motility, and has served as reviewer for many international journals and grant agencies.

A recent review, published by Julia Schwartzman and Edward Ruby from the Department of Medical Microbiology & Immunology at University of Wisconsin-Madison (USA), argues that chemical and physical stresses should be considered a normal attribute of the host symbiotic milieu. Their arguments are as follows. Microorganisms appeared on the Earth as early as 3.4 billion years ago, and as humans…

Although it is well documented that gut microbiota may shape brain function and development, little is known about its impact on the outcome of acute brain injury. A recent study, led by Dr. Josef Anrather, an associate professor of neuroscience at the Weill Cornell Medical College in New York (USA), has found that the commensal gut microbiota could influence the…

A recent review, published by postdoctoral researcher Dr. Eldin Jasarevic from the Department of Animal Biology in the University of Pennsylvania, argues that sex differences influence the development, maturation, and maintenance of the gut microbiome-brain axis throughout the lifespan.   The gut-brain axis (GBA) involves bidirectional communication between the central and enteric nervous systems, which facilitates the integration of peripheral…

A recent study by Andrew Moeller and colleagues has revealed that social interactions can raise microbial diversity in the gut microbiome across chimpanzee generations. The study monitored the effect of chimpanzee sociability on gut microbiome diversity over an eight-year period. Faecal samples were collected and sequenced from 40 Kasakela chimpanzees in Gombe, Tanzania, at different stages of life. In addition,…

It is increasingly clear that brain processing is influenced by the gastrointestinal microbiota; study of the gut-brain axis has shown evidence that gut bacteria interact with the enteric nervous system and the central nervous system. Good brain function depends on neuromediators -- that is, substances that carry messages between neurons, or from a neuron to another type of cell. Could an…

How might microorganisms move from one part of the body to another? Let's begin with the womb, where the concept of fetal colonization has rapidly gained acceptance, indicated by meconium and placental microbe studies. A new stool study reveals virus populations are dynamic in healthy infants. The infant virome is most diverse early in life, then bacteria flourish as viral…
