abstract = {Mapping of multiple receptors of neurotransmitters provides
insight into the spatial distribution of
neurotransmission-relevant molecules in the cerebral cortex.
During development, lack of reelin leads to impaired
migration, disturbed lamination of the hippocampus and
inverted neocortical layering. In the adult, reelin may
regulate synaptic plasticity by modulating neurotransmitter
receptor function. Using quantitative in vitro receptor
autoradiography, different receptors, in particular, the
binding site densities and laminar distribution of various
glutamate, GABA, muscarinic and nicotinic acetylcholine,
serotonin, dopamine and adenosine receptors, were analyzed
in cortical and subcortical structures of reeler and
wild-type brains. Differential changes in the laminar
distribution, maximum binding capacity (B (max)) and
regional density of neurotransmitter receptors were found in
the reeler brain. A decrease of whole brain B (max) was
found for adenosine A(1) and GABA(A) receptors. In the
forebrain, several binding sites were differentially up- or
down-regulated (kainate, A(1), benzodiazepine, 5-HT(1),
M(2), α(1) and α(2)). In the hippocampus, a significant
decrease of GABA(B), 5-HT(1) and A'₁ receptors were
observed. The density of M(2) receptors increased, while
other receptors remained unchanged. In the neocortex, some
receptors demonstrated an obviously inverted laminar
distribution (AMPA, kainate, NMDA, GABA(B), 5-HT(1), M(1),
M(3), nAch), while the distribution of others (A(1),
GABA(A), benzodiazepine, 5-HT(2), muscarinic M(2),
adrenergic α(1), α(2)) seemed to be less affected. Thus,
the laminar receptor distribution is modulated by the
developmental impairment and suggests and reflects partially
the laminar inversion in reeler mice.},
