Neuronal nicotinic acetylcholine receptors (nAChR) are present in
high abundance in the nervous system (Decker et al., 1995). There are a
large number of subunits expressed in the brain that combine to form
multimeric functional receptors. We have generated an 4
nAChR subunit knock-out line and focus on defining the behavioral role
of this receptor subunit. Homozygous mutant mice (Mt) are normal in
size, fertility, and home-cage behavior. Spontaneous unconditioned
motor behavior revealed an ethogram characterized by significant
increases in several topographies of exploratory behavior in Mt
relative to wild-type mice (Wt) over the course of habituation to a
novel environment. Furthermore, the behavior of Mt in the elevated
plus-maze assay was consistent with increased basal levels of anxiety.
In response to nicotine, Wt exhibited early reductions in a number of
behavioral topographies, under both unhabituated and habituated
conditions; conversely, heightened levels of behavioral topographies in
Mt were reduced by nicotine in the late phase of the unhabituated
condition. Ligand autoradiography confirmed the lack of high-affinity
binding to radiolabeled nicotine, cytisine, and epibatidine in the
thalamus, cortex, and caudate putamen, although binding to a number of
discrete nuclei remained. The study confirms the pivotal role played by
the 4 nAChR subunit in the modulation of a number of
constituents of the normal mouse ethogram and in anxiety as assessed
using the plus-maze. Furthermore, the response of Mt to nicotine
administration suggests that persistent nicotine binding sites in the
habenulo-interpeduncular system are sufficient to modulate motor
activity in actively exploring mice.
