Type | induction | Description | By methyl-beta-cyclodextrin. Up-regulated upon chronic morphine injection, in amygdala only, other brain regions remain unaffected. Induction by morphine may affect glutamate uptake in the amygdala, causing mice to develop morphine tolerance and dependence (PubMed:12438930). Was originally reported to be induced by retinoic acid (PubMed:12562531). |
