Downregulation and upregulation of receptors
WebDown-regulation - definition when the number of receptors for a neurotransmitter are decreased, typically in response to an increase in the release of that neurotransmitter. Down-regulation can also refer more generally to the decreasing of any cellular component (e.g., protein, RNA). WebSupporting: 24, Contrasting: 2, Mentioning: 223 - Endotoxin-induced cholestasis is mainly caused by an impaired canalicular secretion. Mrp2, the canalicular multispecific organic anion transporter, is strongly downregulated in this situation, and canalicular bile salt secretion is also reduced. We hypothesized that other adenosine triphosphate-binding …
