Basal and adenosine receptor-stimulated levels of cAMP are reduced in lymphocytes from alcoholic patients.

Abstract: Alcoholism causes serious neurologic disease that may be due, in part, to the ability of ethanol to interact with neural cell membranes and change neuronal function. Adenosine receptors are membrane-bound proteins that appear to mediate some of the effects of ethanol in the brain. Human lymphocytes also have adenosine receptors, and their activation causes increases in cAMP levels. To test the hypothesis that basal and adenosine receptor-stimulated cAMP levels in lymphocytes might be abnormal in alcoholism, we… Show more

“…Several lines of evidence indicate that alcoholic individuals have abnormal adenylyl cyclase signal transduction and that genetic determinants may account for some of these differences. Stimulated cAMP production in freshly isolated platelets and lymphocytes is reduced in alcoholics compared to nonalcoholic controls (11,12). Moreover, after multiple generations in culture, lymphocytes from alcoholics not only recover their responsiveness but develop enhanced sensitivity to factors that stimulate cAMP (13).…”

“…Cell Culture-NG108-15 neuroblastoma ϫ glioma hybrid cells obtained from the cell culture facility at the University of California (San Francisco) were grown in 10% Serum Plus (JRH Biosciences) at 37°C in a 10% CO 2 incubator as described previously (12). All cells were maintained for 3 days in complete defined medium (13).…”

“…After chronic ethanol exposure, these cells require ethanol to reach normal levels of adenosine receptor-stimulated cAMP, which may indicate a form of cellular dependence. 23,24 Lymphocytes from chronic alcoholic patients exhibited reduced basal and reduced stimulated cAMP levels and increased resistance to ethanol stimulation of adenosine receptor-dependent cAMP accumulation. 23,25 Recent studies have focused on adenylyl cyclase, which is activated via receptor-modulated G-protein and generates cAMP.…”
