Alterations in the Microbiome Are Associated with Changes in Bone Quality

  |  

Moreover, the changes in splenic immune cell populations in the treated mice suggested to the researchers an association between alteration in bone tissue material properties and immune cell populations. “We consider the effects of the microbiota on the immune system to be a likely explanation for the differences in bone tissue material properties in the current study,” write the authors in their discussion. “Disruption of the gut microbiota with antibiotics reduced CD20+ B and CD3+ T cell populations and was correlated with reduced whole bone strength. Similarly, untreated TLR5KO mice also had reduced CD20+ B and CD3+ T cell populations.”

    The human intestinal microbiota is home to more than 1,000 bacterial species, containing approximately 3 million genes, many of which code for functions that have the potential to affect human physiology.1 Smaller numbers of organisms are also present in the skin, upper gastrointestinal tract, female reproductive tract and the oro- and nasopharynx. As tools have…

    Research Provides Insight into Impact of Microbiome on Health, Rheumatic Disease

    The microbiome comprises diverse microbial flora, including bacteria, viruses and fungi, that live on mucosal surfaces, predominantly the skin and digestive tract. Microbes evolved billions of years prior to the development of modern Homo sapiens 200,000 years ago; we have always existed with their ubiquitous presence. Despite this, the first microbe was not visualized until…

    Mouse Research Suggests the Microbiome Is Related to Lupus

    Research in type I interferon (IFN) driven mouse models of systemic lupus erythematosus (SLE) suggests the microbiome may play a role in the development of autoimmunity. Additionally, changes in diet may induce protective effects in the gut.1 “Microbes in the gut worsen a lupus model related to the interferon pathway,” says Martin A. Kriegel, MD,…
