Eating disorders are a public health issue. It has been recently reported the importance of immune system modifications in eating disorders physiopathology, involving autoantibodies directed against neuropeptides regulating food intake. A recent study of laboratory INSERM 1073 showed the existence of an intestinal bacterial protein exhibiting structural similarities with α-MSH: ClpB. The autoAc directed against the latter also react with α-MSH because of these similarity of structures, thus leading to a potential digestive origin of these autoAc. To consolidate this new etiopathogenic assumption, a large clinical study is necessary with analysis of patients autoAc profiles. a monocentric study with inclusion of 240 patients over 2 years and 80 healthy volunteers is proposed.~This study should lead to the validation of the concept of the autoAc directed against the neuropeptides involved in food intake regulation. Nutritional modulations (probiotic, amino-acid…) could constitute an interesting therapeutic perspective in the future.
