Abstract
BACKGROUND Dysfunction of the cholinergic muscarinic receptors has been implicated in the pathology of bipolar disorder and major depressive disorder. However, there is conflicting evidence regarding the association between individual muscarinic receptors and the two disorders. METHODS We used the muscarinic receptor selective radioligands [3H]pirenzepine, [3H]AFDX-384 and [3H]4-DAMP to measure the levels of muscarinic(1) (CHRM1) and muscarinic(4) (CHRM4) receptors, muscarinic(2) (CHRM2) and muscarinic(4) (CHRM4) receptors and muscarinic(3) (CHRM3) receptor, respectively. Radioligand binding was measured in Brodmann's area (BA) 10 of the rostral prefrontal cortex, BA 46 of the dorsolateral prefrontal cortex and BA 40 of the parietal cortex in the post-mortem CNS from subjects with bipolar disorder or major depressive disorder and control subjects. RESULTS [3H]AFDX-384 binding was decreased in BA 46 in both bipolar disorder (p<0.01) and major depressive disorder (p<0.05). [3H]4-DAMP binding was decreased in BA 10 in bipolar disorder (p<0.05) but not major depressive disorder (p>0.05). [3H]AFDX-384 and [3H]4-DAMP binding were unaltered in any other cortical region examined for either disorder (p>0.05). [3H]pirenzepine binding was not significantly altered in either disorder in any cortical region examined (p>0.05). LIMITATIONS 9 bipolar disorder, 9 major depressive disorder and 19 control subjects were used in the study. CONCLUSION Our data is consistent with previously published data implicating a role for CHRM2 receptors in the pathology of bipolar and major depressive disorder. The demonstration of a novel association between decreased CHRM3 receptor expression and bipolar disorder suggests bipolar and major depressive disorder differs in the underlying nature of their cholinergic dysfunction.

Abstract
The G-protein coupled metabotropic glutamate receptors (GRMs/mGluRs) have been implicated in the aetiology of schizophrenia as they modulate the NMDA response and that of other neurotransmitters including dopamine and GABA.(1-3) Electrophysiological studies in GRM subtype 5 knockout mice reveal, in one study, a sensorimotor gating deficit characteristic of schizophrenia and in another, a key rôle for this gene in the modulation of hippocampal NMDA-dependent synaptic plasticity. In humans, GRM5 levels are increased in certain pyramidal cell neurons in schizophrenics vs controls.(6) Finally, GRM5 has been mapped to 11q14, neighbouring a translocation that segregates with schizophrenia and related psychoses in a large Scottish family, F23 (MLOD score 6.0). We determined the intron/exon structure of GRM5 and identified a novel intragenic microsatellite. A case-control association study identified a significant difference in allele frequency distribution between schizophrenics and controls (P = 0.04). This is suggestive of involvement of the GRM5 gene in schizophrenia in this population.
