Cm. Araki et De. Hamassaki-britto, Calretinin co-localizes with the NMDA receptor subunit NR1 in cholinergic amacrine cells of the rat retina, BRAIN RES, 869(1-2), 2000, pp. 220-224
Immunohistochemistry was used to verify whether choline-acetiltransferase c
olocalizes with calcium-binding proteins and NMDA receptor subunit NR1 in t
he rat retina. Whereas calbindin and parvalbumin were not observed in choli
nergic amacrine cells, calretinin and NR1 were very frequently colocalized
with ChAT. Calretinin/NR1-positive cells were also shown, suggesting that c
alretinin in cholinergic cells of the rat may be related to the buffering o
f excess intracellular calcium generated by activation of NMDA receptors. (
