In particular, research showed that gut bacterial caseinolytic protease B (ClpB), produced by several intestinal microorganisms, is implicated in the production of autoantibodies cross-reactive with α-melanocyte-stimulating hormone (α-MSH), which are associated with altered feeding and emotional behaviors in patients with EDs, in particular those with BN and BED (Tennoune et al., 2014). This evidence concerns the gene CLPB and X-linked cone dysfunction syndrome with myopia.
