Abstract

The exact factors contributing to the pathogenesis of type 2 diabetes remain elusive. Lately, it was suggested that inflammation and activation of the innate immune system could be linked to type 2 diabetes pathogenesis and also to the development of common diabetic complications, mainly atherosclerosis. The aim of this study was to investigate the role of monocytes in this sub-clinical inflammatory state and test 1,25-dihydroxyvitamin D(3), the active form of Vitamin D, as an anti-inflammatory agent. For this purpose, monocytes from type 2 diabetic patients were compared to monocytes from healthy controls and type 1 diabetic patients. The expression profile of inflammatory markers in freshly isolated and immune-stimulated monocytes was measured by quantitative real-time RT-PCR. Type 2 diabetic patients showed significantly higher expression levels of TNF-alpha, IL-6, IL-1, IL-8, COX-2, ICAM-1 and B7-1 compared to controls and type 1 diabetic patients. 1,25-Dihydroxyvitamin D(3) was able to down-regulate the expression of TNF-alpha, IL-6, IL-1, and IL-8, confirming its immunomodulatory properties. From these data we concluded that monocytes from type 2 diabetic patients have a pro-inflammatory profile. In addition, 1,25-dihydroxyvitamin D(3) was able to modulate inflammation in these monocytes.

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.
