Subjects with restrictive anorexia nervosa (AN) display increased basal plasma levels of ghrelin that normalize after refeeding. The mechanism responsible for increased ghrelin levels in AN is unknown. We studied if changes of ghrelin reactive autoantibodies (autoAbs) could explain elevated plasma ghrelin in AN.Plasma levels of autoAbs reactive with ghrelin and des-acyl ghrelin were measured by enzyme-linked...
Recent findings of autoantibodies directed against melanocortin peptides suggest that these autoantibodies may represent a source of variability in peptidergic signaling that can be responsible for altered appetite and emotion in eating disorders. However, it is still unknown if autoantibodies directed against some other appetite-regulating neuropeptides and peptide hormones exist in healthy human...
