| Research Abstract |
Using antisera against tyrosine hydroxylase (TH) and purified beta_2-adrenergic receptors (beta_2-AdR), we found that TH- and AdR-like immunoreactivities coexisted in large amacrine cells. These findings indicated an association between dopamine-containing amacrine cells and adrenergic amacrine cells. The present study also showed that amacrine cells with TH-like immunoreactivity have vitaminDdependent calcium-binding protein (calbindin. 27000 kDa)-like immunoreactivity as well, suggesting that calbindin plays an important post-synaptic role in dopaminergic amacrine cells.
