Abstract
Several lines of data from human and animal studies have suggested a role of thyroid hormone in the regulation of cholinergic neurons in the adult brain. In this study we have investigated the content of nerve growth factor (NGF) and the expression of NGF low affinity receptor (p75(LNGFR)) in the basal forebrain of adult hypothyroid rats. We describe an increase of both NGF and p75(LNGFR) expression in the basal forebrain of adult hypothyroid rats. The administration of colchicine up-regulates p75(LNGFR) expression in both hypo- and control rats, whereas it fails to down-regulate choline acetyl transferase mRNA expression during hypothyroidism. These data offer a possible neurobiological explanation to cognitive defects observed during adult hypothyroidism in humans.Entities:
