The Role of “Mixed” Orexigenic and Anorexigenic Signals and Autoantibodies Reacting with Appetite-Regulating Neuropeptides and Peptides of the Adipose Tissue-Gut-Brain Axis: Relevance to Food Intake and Nutritional Status in Patients with Anorexia Nervosa and Bulimia Nervosa

Table 1

Summary of the most relevant changes of adipose tissue-gut-brain axis plasma peptides stimulating appetite and autoantibodies against acylated ghrelin before and after refeeding in patients with anorexia nervosa (AN) and bulimia nervosa (BN), and the presence of autoantibodies against neuropeptide Y (NPY) and ghrelin in healthy women and autoantibodies against NPY in depressive disorder. Immunoglobulin (Ig) M, IgG, and IgA classes.
