Toll-like receptors play an important role in host defense. TLR-7 recognizes viral ssRNA, but also plays a role in the development of systemic lupus erythematosus (SLE). Genetic ablation of a similar receptor, TLR-9, results in opposite effects, with severe disease and kidney involvement. The mechanism of how this works remains unknown.

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,…
Doctors have had few options to treat the chronic rheumatoid arthritis-like symptoms associated with chikungunya virus infections beyond over-the-counter pain relievers. A recent study in Science Translational Medicine has spurred new optimism by finding that a combination therapy—the anti-rheumatic drug abatacept paired with a chikungunya-neutralizing monoclonal antibody—abolished acute symptoms in infected mice.1 The strategy must…
