Scientists shed light on a key molecular mechanism of autoimmune and inflammatory diseases  

An international team of researchers has unraveled a crucial aspect of the molecular basis of autoimmune and inflammatory diseases such as psoriasis, rheumatoid arthritis and Crohn's disease. Focusing on the immunomodulatory cytokine IL-23 they discovered that its pro-inflammatory activity, which underlies a wide range of inflammatory diseases, critically depends on structural activation of the cytokine by its receptor, IL-23R.

Scientists compared fecal samples from surfers and non-surfers to assess whether the surfers' guts contained E. coli bacteria that were able to grow in the presence of the antibiotic cefotaxime. Cefotaxime has previously been prescribed to kill off these bacteria, but some have acquired genes that enable them to survive this treatment. The study found that 13 of 143 (9 percent) of surfers were colonized by these resistant bacteria, compared to just four of 130 (3 percent) of non-surfers swabbed.
