We investigated a potential role for the soluble interleukin-6 receptor (sIL-6R) in modulating interleukin-6 (IL-6) function in the central nervous system by assessing IL-6 and sIL-6R effects on beta-amyloid precursor protein (beta-APP) transcription and expression in cells of human neuronal origin. Cells transfected with a luciferase reporter plasmid(More)
We compared the concentration of mRNA encoding the m1 and m2 muscarinic receptors in several brain regions obtained from young (5-8 months) and aged (24-28 months) male Fischer 344 rats. DNA-excess solution hybridization was employed as a quantitative measure of mRNA concentration. The results indicate the absence of changes in the m1 receptor message with(More)
We determined the concentration of the messenger RNA species which encode four (m1-m4) of the five cloned muscarinic receptors in brains of Alzheimer's disease patients as compared to age-matched controls. Assays were performed using the quantitative method of DNA-excess solution hybridization in the cerebral cortex (frontal, temporal and occipital),(More)
The thalamo-(fronto)cortical circuit is involved in sleep regulation, and its dysfunction might contribute to the pathophysiology of chronic primary insomnia. To obtain more evidence of the involvement of the circuit, we studied 23 patients with chronic primary insomnia and 28 healthy volunteers via the assessment of mismatch negativity (MMN) elicited by(More)
The first putative extracellular domains of both m1 and m2 muscarinic receptors contain a triplet of amino acid residues consisting of leucine (L), tyrosine (Y), and threonine (T). This triplet is repeated as LYTLYT in m2 receptors. However, it is repeated in a transposed fashion (LYTTYL) in the sequence of m1 receptors. In this work we employed(More)
