Abstract

Interleukin-10 (IL-10) has a critical role in the regulation of immune responses. The relative contribution of genetic and environmental factors to IL-10 production is under debate. We performed a twin study in 246 monozygotic and dizygotic twins to assess the heritability of IL-10 production after LPS stimulation in whole blood. In addition, the influence of promoter single nucleotide polymorphisms (-1082, -819 and -592) on transcriptional activity and their binding to nuclear factors was studied in luciferase reporter gene and electrophoretic mobility shift assays. IL-10 production showed a genetic determination with a heritability of 0.5. Decreasing body mass index (BMI), smoking and female gender lead to decreased IL-10 production. In monocytes, the -1082A allele showed higher binding affinity to the transcription factor PU.1 resulting in decreased transcriptional activity of -1082A promoter haplotypes. Genetic determination of IL-10 secretion is probably lower than that previously reported. Fifty percent of the observed variability explained by genetic factors. Female individuals produce less IL-10 than male subjects. Environmental factors like smoking and decreasing BMI exert suppressing effects on IL-10 production. Although the -1082A allele shows higher binding affinity to the PU.1 transcription factor and lower transcriptional activity, this polymorphism probably explains only a small fraction of the observed heritability.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
