Drug and neurotransmitter receptors are neuronal markers and can be indicators of neuronal connectivity. Knowledge of alterations in receptors in amyotrophic lateral sclerosis should contribute to our understanding of normal spinal cord neurotransmitter systems as well as of the pathophysiology of amyotrophic lateral sclerosis. We therefore used a sensitive, light microscopic in vitro labeling receptor autoradiographic technique to map and quantitate muscarinic cholinergic, glycinergic, and benzodiazepine receptors in three levels of spinal cord from six patients with amyotrophic lateral sclerosis and six age and sex\u2010matched control patients. In control tissues, the receptor distributions were similar in the three levels of spinal cord and also similar to those found in previous studies with animals. In amyotrophic lateral sclerosis, major reductions in receptor densities were noted in Rexed layer IX, the region containing motor neurons. Reductions were noted in other laminae as well, particularly for muscarinic receptors. The changes in muscarinic receptors were caused solely by changes in high\u2010affinity agonist sites. Reductions in glycine and muscarinic receptors were highly correlated with the degree of motor neuron loss found in the amyotrophic lateral sclerosis patients. The findings in this study point out the usefulness of this receptor mapping technique in understanding the changes in neuronal populations that occur in the degenerative neurological diseases.<\/jats:p>","DOI":"10.1002\/ana.410140103","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T13:50:26Z","timestamp":1104587426000},"page":"8-16","source":"Crossref","is-referenced-by-count":132,"title":["Amyotrophic
