Abstract
One hundred fifty-nine individuals were typed for HLA-A and B antigens and levels of isoproterenol-stimulated, lymphocyte cAMP. No significant age, sex, or caffeine effects on the natural log of the lymphocyte cAMP variable (ln cAMP) were found. A comparison of mean ln cAMP levels between individuals who carried a particular antigen (homozygous or heterozygous) and individuals who did not carry the antigen identified a highly significant decrease in ln cAMP levels associated with the HLA-B18 antigen. We estimated that 18.9% of the variability in ln cAMP was attributable to the HLA-B18 antigen. In addition, 38% of the variability in ln cAMP was attributable to factors that aggregate in families that were independent of the HLA-B18 effect. A weaker association of A10 with lymphocyte cAMP might be due to linkage disequilibrium between A10 and B18.Entities:
