Induction of neuronal functions: acetylcholine-induced acetylcholinesterase activity in mouse neuroblastoma cells.

abstract：:Hereditary hemochromatosis (HH) is a common autosomal recessive disorder of iron metabolism that leads to excessive iron storage in the liver and other organs. Recently, between 83 and 100% of HH patients have been found to be homozygous for the same mutation in a novel major histocompatibility complex class I-like ge...
