Аденозинзависимая регуляция экспрессии паракринных факторов в моноцитах венозной крови человека

The flow cytometry analysis of human peripheral blood monocytes separated by a two step density gradient centrifugation is reported. The expression of mRNA level of adenosine receptor (AdoR) subtypes (A1, A2A, A2B and A3) and interleukin 6 (IL-6), interleukin 8 (IL-8) and vascular endothelial growth factor (VEGF) in monocytes were determined using real-time PCR. We found considerable variation across individuals in mRNA expression levels of paracrine factors after the stimulation of adenosine receptors. Our findings suggests the role of adenosinergic system accounted for interindividual differences in monocyte activation.Проведено исследование экспрессии поверхностных маркеров: CD1a, CD14, CD209, а также экспрессии мРНКаденозиновых рецепторов типов А1, А2А, А2В и А3, интерлейкина-6 и -8 (ИЛ-6 и ИЛ-8), фактора роста эндотелия сосудов (vascular endothelial growth factor — VEGF) в моноцитах человека. В данных клетках выявлено наличие широкого спектра индивидуальных различий в аденозинзависимой регуляции экспрессии паракринных факторов (ИЛ-6, ИЛ-8 и VEGF)
