The human gut microbiome is a complex, highly-evolved commensal community with an integral role in your response to disease and how well you maintain homeostasis. While commensal bacteria vary from person to person, a person’s specific microbiome should contain the same relative percentage of bacterial species over their lifespan. The balance of this community can […]
Most researchers know the pain of trying and failing to replicate a published experiment. This can result from something as simple as a poorly written methods section, in which important experimental details have been omitted. Barnett and Gibson recently called out the importance of an in vivo experimental detail that is commonly left out and […]
Rensselaer, NY — April 15, 2019 – Taconic Biosciences, a global leader in providing genetically engineered rodent model solutions, announces the launch of TruBIOME™, a first of its kind solution enabling the generation and maintenance of mice with custom microbiome profiles. TruBIOME™ was developed to meet the research community’s need for a microbiome solution that […]

NEW PRESENTATIONS: Ultra-high Resolution Microbiome Taxonomic Profiling Enabled by Novel High-throughput, High-resolution Assay Design Mark Driscoll, Ph.D., Co-Founder and Chief […]
For the past several years, science has been plagued by what some consider a reproducibility crisis—the idea that many published studies don’t yield the same results when repeated by other scientists, or sometimes even by the same scientists. Surveys and studies have suggested myriad reasons such as unreliable reagents and cell lines, selective statistics, a […]
NORTH BETHESDA, Md., April 3, 2019 /PRNewswire/ — The Foundation for the National Institutes of Health, Inc. (FNIH) is delighted to name Yasmine Belkaid, Ph.D., the winner of the 2019 Lurie Prize in Biomedical Sciences for blazing a trail in understanding the microbiome’s significant role in immune regulation. The human body houses trillions of microscopic […]
RENSSELAER, N.Y., April 01, 2019 (GLOBE NEWSWIRE) — Taconic Biosciences, a global leader in providing genetically engineered rodent model solutions, announces it has obtained a license to the Wild Mouse gut microbiome from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), part of the National Institutes of Health (NIH). Investigators at the […]
New research is regularly being published on the connection between the gut microbiome and the central nervous system (CNS) — together known as the gut-brain axis. Alterations in the composition of intestinal microbiota have also been associated with antibiotic use and the progression of infectious diseases. This Taconic Insight highlights the link between the microbiome […]
ABSTRACT AIMS NOD2 and CD1d play a key role in innate immunity by recognizing conserved molecular patterns of pathogens. While NOD2−/− and CD1d−/− mice display structural and functional alterations in Paneth cells, animal studies have reported no impact of NOD2 or CD1d deficiency on experimental colitis. NOD2 mutations increase the susceptibility to inflammatory bowel diseases […]
ABSTRACT MHC molecules are essential for the adaptive immune response, and they are the most polymorphic genetic loci in vertebrates. Extreme genetic variation at these loci is paradoxical given their central importance to host health. Classic models of MHC gene evolution center on antagonistic host-pathogen interactions to promote gene diversification and allelic diversity in host […]
ABSTRACT The gut microbiome is composed of an enormous number of microorganisms, generally regarded as commensal bacteria. Resident gut bacteria are an important contributor to health and significant evidence suggests that the presence of healthy and diverse gut microbiota is important for normal cognitive and emotional processing. Here we measured the expression of monoamine neurotransmitter-related […]
ABSTRACT We demonstrated that an antibiotic cocktail (ABX)-perturbed gut microbiome is associated with reduced amyloid-β (Aβ) plaque pathology and astrogliosis in the male amyloid precursor protein (APP)SWE/presenilin 1 (PS1)ΔE9 transgenic model of Aβ amyloidosis. We now show that in an independent, aggressive APPSWE/PS1L166P (APPPS1-21) mouse model of Aβ amyloidosis, an ABX-perturbed gut microbiome is associated […]
ABSTRACT The diverse bacterial populations that comprise the commensal microbiome of the human intestine play a central role in health and disease. A method that sustains complex microbial communities in direct contact with living human intestinal cells and their overlying mucus layer in vitro would thus enable the investigation of host–microbiome interactions. Here, we show […]
ABSTRACT The gut commensal Bacteroides fragilis or its capsular polysaccharide A (PSA) can prevent various peripheral and CNS sterile inflammatory disorders. Fatal herpes simplex encephalitis (HSE) results from immune pathology caused by uncontrolled invasion of the brainstem by inflammatory monocytes and neutrophils. Here we assess the immunomodulatory potential of PSA in HSE by infecting PSA […]
ABSTRACT Gut microbiota play a key role in the regulation of obesity and associated metabolic disorders. To study the relationship between them, antibiotics have been widely used to generate pseudo-germ-free rodents as control models. However, it is not clear whether antibiotics impact an animal’s metabolic phenotype. Therefore, the effect of antibiotics-induced gut microbial perturbations on […]
ABSTRACT Dietary intervention during early life has a significant impact on colonization of the gut microbiota. In addition, some polysaccharides have the potential to selectively stimulate the growth and metabolic activity of intestinal bacteria associated with health and well-being. However, less is known about the effect of polysaccharides on the development of gut microbiota in […]
ABSTRACT Diabetic kidney disease is a major cause of renal failure that urgently necessitates a breakthrough in disease management. Here we show using untargeted metabolomics that levels of phenyl sulfate, a gut microbiota-derived metabolite, increase with the progression of diabetes in rats overexpressing human uremic toxin transporter SLCO4C1 in the kidney, and are decreased in […]
Significance Studies using experimental models have indicated that multiple sclerosis (MS)-like disease can be triggered in the gut following interactions of brain autoimmune T lymphocytes with local microbiota.
Gnotobiotics, edited by Trenton Schoeb and Kathryn Eaton, is invaluable to those developing or managing gnotobiotic facilities.
Brigham Young University: We all know that a poor diet is unhealthy, but a new BYU study finds that stress may just as harmful to our bodies as a really bad diet.
Abstract For more than three decades it has been recognized that small amounts of vector saliva can significantly alter the infectivity of vector-borne pathogens and subsequent in vivo dynamics.
Abstract Mouse models have enabled breakthroughs in our understanding of the immune system, but it has become increasingly popular to emphasize their shortcomings when translating observations to humans.
