K. Ohara et al., NORMAL SEQUENCES OF MUSCARINIC ACETYLCHOLINE-RECEPTORS (M1 AND M2) INPATIENTS WITH ALZHEIMERS-DISEASE AND VASCULAR DEMENTIA, Neuroscience letters, 178(1), 1994, pp. 23-26
The genes for muscarinic acetylcholine receptors, m1 and m2, were stud
ied in autopsied brains from nine Alzheimer's disease. six vascular de
mentia and three control. The genes were amplified by the polymerase c
hain reaction and sequenced by the dideoxy method. Although one DNA po
lymorphism was found in m1, the deduced amino acid sequences of the mu
scarinic acetylcholine receptor were unchanged. The amino acid sequenc
es of m1 and m2 in Alzheimer's disease and vascular dementia were inta
ct.
