Anti Inflammatory Property of PDRN—An in Vitro Study on Cultured Macrophages
Open accessAbstract
Skin aging and most age-related diseases are associated with a low-grade chronic inflammation. The nucleoside adenosine, a potent endogenous anti-inflammatory agent, is deeply involved in inflammatory diseases and, by interaction with the adenosine A2 receptor (A2AR) it immediately promotes a mechanism of defence against the inflammatory damage. The aim of our study was to investigate whether polydeoxyribonucleotide (PDRN), a mixture of deoxyribonucleotides polymers of different lengths that like adenosine, binds the A2A receptor, can reduce the inflammatory state in the macrophage cell line. RAW264.7, murine macrophage cells, were incubated with PDRN in the presence and in the absence of lipopolysaccaride (LPS), which was the major component of the outer membrane of gram-negative bacteria and which acted as a strong macrophage activator. We assessed the production of nitric oxide and the secretion of inflammatory mediators (i.e., TNF-α, IL-10, IL-12 and VEGF-A). Our data showed that PDRN produced a significant decrease of inflammation in macrophages pre-stimulated with LPS, assessed in terms of the nitric oxide content (p 2A receptor, contributed to a great extent towards reducing inflammation.

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.
