Breaking down IgA: Tomasiella immunophila enlightens microbiome–immune interactions

The recent discovery by Lu and colleagues of Tomasiella immunophila, a bacterium that degrades IgA, offers insights into microbial influences on mucosal immunity and evolutionary immune trade-offs. By modulating IgA titers, T. immunophila influences the dy ...

Fostering of advanced mutualism with gut microbiota by Immunoglobulin A

Duncan-Bruce Sutherland

Immunoglobulin A (IgA), the most abundantly secreted antibody isotype in mammals, not only provides direct immune protection to neonates via maternal milk but also helps program the infant immune system by regulating the microbiota. IgA continues to mainta ...

Immune Antibodies and Helminth Products Drive CXCR2-Dependent Macrophage-Myofibroblast Crosstalk to Promote Intestinal Repair

Jérôme Bürgi, Nicola Harris, Benjamin John Marsland, Julia Esser-von Bieren, Beatrice Volpe, Duncan-Bruce Sutherland

Helminth parasites can cause considerable damage when migrating through host tissues, thus making rapid tissue repair imperative to prevent bleeding and bacterial dissemination particularly during enteric infection. However, how protective type 2 responses ...

Gut Reactions: Eosinophils Add another String to Their Bow

Duncan-Bruce Sutherland

Eosinophils are found in abundance in the gut. In this issue of Immunity, Chu et al. (2014) report that eosinophil-deficient mice have impaired intestinal immunoglobulin A production, accompanied by a disrupted mucosal layer and alterations in microbiota d ...
