Adropin is a peptide hormone produced in the liver and brain[9,10] involved in energy homeostasis, glucose and fatty acid metabolism,[11,12] found at high concentrations in the brain and involved in developing the cerebellum.[13] We decided to investigate the level of adropin in MS, a neurodegenerative disease, due to its potential neuroprotective effects in the central nervous system. Here, ENHO is linked to myeloid sarcoma.
