A recent review suggests that the peptide Ab associated with AD may have antimicrobial functions via a new pathway that involves trapping invading microorganisms, including bacteria (such as Salmonella enterica), fungi (such as Candida albicans), viruses (such as herpes simplex virus) and parasites (such as Toxoplasma gondii).
The Harvard Probiotics Symposium, “Gut health, microbiota & probiotics throughout the lifespan: Metabolic & brain function”, was held on September 15th and 16th at Harvard Medical School in Boston (USA).

A recent study, led by Dr. Deanna L. Gibson from the Department of Biology at the University of British Columbia (Canada), has found that cardiorespiratory fitness is correlated with increased microbial diversity and increased production of faecal butyrate in healthy humans.

A recent study, led by Dr. Mauro Costa-Mattioli from the Baylor College of Medicine in Houston, Texas (USA), has found that the reintroduction of a commensal bacterial strain can reverse asocial behaviours in mice that are seen in autism spectrum disorders (ASDs).
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.
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.

A new study published in PLOS one, led by Dr. Vincent Cassone from the Department of Biology, University of Kentucky (USA), provided insights on how the host clock regulates the microbiome. Researchers found that a species of human gut bacteria, Enterobacter aerogenes, has its own circadian rhythm and responds to fluctuations in the hormone melatonin.

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.
A recent review argues that chemical and physical stresses should be considered a normal attribute of the host symbiotic milieu.
