    Right now, as you read this article, you are under alien surveillance. If you lower these pages or raise your eyes from the computer screen, you may think you see your co-worker or life partner across the room, but none of these people are who they present themselves to be, or at least not fully.

  • No Known Expiration Date

    “Hell, no,” Richard Isaacson bellows when asked whether some form of cognitive decline is inevitable with age, especially for those genetically tilted toward the disabling dementia of Alzheimer’s disease. Then, in the interest of science, an enterprise customarily cloaked in the conjectural, he restrains himself.

  • Researchers Say Gut Microbiota Affects Our Physiology

    An international team of researchers from Spain and the UK has found that the protein TLR2 (Toll-like receptor 2) — a critical detector of the microbiota found in the intestine — regulates levels of serotonin, a neurotransmitter intimately connected to the brain’s regulation of appetite, sleep, and mood.

  • A Gut Makeover for the New Year
    03-sci-gutbacteria-master768


    If you’re making resolutions for a healthier new year, consider a gut makeover. Refashioning the community of bacteria and other microbes living in your intestinal tract, collectively known as the gut microbiome, could be a good long-term investment in your health.

  • Vitamin D Improves Gut Microbiota, Study Finds

    Obesity-associated microbiome composition can persist after weight loss, affecting the exchange of metabolites between a mouse and its resident bugs, researchers report.

  • How Diet Influences Host-Microbiome Communication in Mice
    dna_methylation


    Researchers are beginning to decipher the metabolic language of the microbiome, and determine how gut microbes communicate with host tissue. Shortly after we finish a good meal, our resident microbes spring into action. The bacteria, viruses, and fungi that inhabit our guts send out metabolites that prepare our organs for the incoming nutrients.

    Anthony L. Komaroff, MD, Brigham and Women’s Hospital, Harvard Medical School, Boston, Massachusetts, shares his viewpoint in JAMA. Published online December 22, 2016: Obesity and type 2 diabetes mellitus are influenced both by genes and lifestyle. That is not news. However, the genes in the human microbiome also may play an important role, and that […]

  • Housing Systems Influence Gut Microbiota Composition of Sows but Not of Their Piglets
    journal.pone.0170051.g001


    Abstract Different housing systems can be used in pig production and little is known about their effect on gut microbiota composition. In this study we characterized fecal microbiota by sequencing the rRNA genes in sows kept during gestation in conventional pens with a slatted floor and in enriched pens with a floor covered with deep […]

    Abstract Metabolic syndrome (MetS), characterized as obesity, insulin resistance, and non-alcoholic fatty liver diseases (NAFLD), is associated with vitamin D insufficiency/deficiency in epidemiological studies, while the underlying mechanism is poorly addressed. On the other hand, disorder of gut microbiota, namely dysbiosis, is known to cause MetS and NAFLD.

    Abstract Astrocytes have important roles in the central nervous system (CNS) during health and disease. Through genome-wide analyses we detected a transcriptional response to type I interferons (IFN-Is) in astrocytes during experimental CNS autoimmunity and also in CNS lesions from patients with multiple sclerosis (MS).
