| Deletion of β4 subunit in knockout mice has little effect on total [3H]- or [125I]-epibatidine binding with the exception of a partial reduction in the signal intensity in the fasiculus retroflexus, interpeduncular nucleus and the inferior colliculus. The effects of β4 gene deletion were more readily observable when cytisine was included in the incubation with [3H]- or [125I]-epibatidine. Under these experimental conditions, robust effects could be observed in the medial habenula, the fasiculus retroflexis, the interpeducular nucleus and the inferior colliculus, all of which expressed high levels of cytisine-resistant [125I]epibatidine binding [1,10]. Expression of β4 mRNA in rhesus monkey (Macaca mulatta) brain is similar to that described in rodents. High expression is detected in thalamic nuclei, substantia nigra pars compacta and vertral tegmental area. Expression is also detected in cortex (layer VI showing the highest level of expression) and lower levles in hippocampus and caudate [4]. Expression of β4 mRNA in suirrel monkey (Samimiri sciureus) appears to differ from that in rodents or macaques. High levels of expression brain have been detected in caudate, putamen and hippocampus. However, compared to expression levels in the cotex, levels of expression were relatively low in thalamic nuclei, substantia nigra pars compacta and medial habenula [6]. |
