| Outline of Final Research Achievements |
The present study focused on several members of nuclear receptor family that acted as ligand-regulated transcription factors, and found that a natural compound macelignan with PPARγ agonist activity protected dopaminergic neurons in midbrain tissues via promotion of M2 activation of microglia. On the other hand, the present study also demonstrated that agonists at VDR / RXR and an agonist at RAR suppressed M1 activation of microglia via inhibition of recruitment of another transcription factor NF-κB, in a MAP kinase-dependent manner and a MAP kinase-independent manner, respectively.
