Intestinal Bacteria Modulate Inflammatory Arthritis
Review of paper published by W.K. Jubair et al. which analyzes how intestinal microbiota changes during the development Collagen-Induced Arthritis in mice. The study continues by using broad-spectrum antibiotics to observe the time-dependent effects that microbiota exert on autoimmunity. Read More
Different Bacterial Pathogens May Affect Serological Disease Markers in RRP and non-RRP Rheumatoid Arthritis
Summary of Terato et al. (2018) which studied correlations between antibody responses to common bacterial pathogens (E. coli LPS, P. gingivalis LPS, and peptioglycan-polysaccharide) and rheumatoid arthritis disease markers. The results suggest that different bacterial pathogens may be involved in evoking serological disease markers in RRP and non-RRP rheumatoid arthritis, and may contribute to the different disease outcomes in these patient groups. This paper lays the groundwork for studying rheumatoid arthritis and other autoimmune diseases as perturbations of gastrointestinal bacterial populations rather than a malfunctioning immune response.

Bifidobacterium infantis reduces inflammation in mouse models of asthma and food allergies
A study conducted at Shenzhen Children's Hospital demonstrates how oral feeding of B. infantis can reduce signs of inflammation in ovalbumin-induced asthma and β-lactoglobulin-induced food allergy in mice. This study adds to a growing body of research suggesting that manipulation of gut microbiota is a viable treatment for allergies and autoimmune diseases. Read More
Influence of Diet and Probiotic Bacteria on Intestinal Barrier Function
The permeability of the intestinal epithelial barrier plays a significant role in an individual's systemic exposure to LPS and other bacterial toxins. The complex relationship between diet and intestinal permeability is not entirely clear, however the article reviewed here presents evidence that a probiotic bacteria, L. gasseri SBT2055, may be able to improve intestinal permeability. This research can lead to new strategies for treating metabolic disorders like obesity. Read More
