INFLUENCE OF SOLUBLE PLACENTADERIVED FACTORS UPON EXPRESSION OF SURFACE RECEPTORS ON THP-1 CELLS
Abstract. During the passage through the utero-placental circulation, peripheral blood monocytes are exposed to action of various soluble placenta-derived factors. Subsequently these cells migrate to placental tissue and play a key role in regulation of placental growth and development. We investiga...

| Sumario: | Abstract. During the passage through the utero-placental circulation, peripheral blood monocytes are exposed to action of various soluble placenta-derived factors. Subsequently these cells migrate to placental tissue and play a key role in regulation of placental growth and development. We investigated the influence of placental secretory factors upon expression of THP-1 cells surface receptors during normal pregnancy, and pregnancy complicated with preeclampsia. Soluble placenta-derived factors produced by the third-trimester placenta caused reduced intensity of CD11а, CD18, CD54, CD14, TRAIL and VEGFR1 expression on THP-1 cells, as compared with the first-trimester placental extracts. Soluble placenta-derived factors from preeclamptic placenta caused an increased intensity of CD18 and CD54 expression by THP-1 cells and decreased intensity of VEGFR1 expression in comparison to normal pregnancy. The work was supported by grants of the President of the Russian Federation № НШ-131.2012.7, СП-3492.2013.4 МК-1580.2013.7 and by grant РФФИ № 13-04-00304 А. |
