Antiphospholipid syndrome and monocytes: new aspects
Original language description
After discovery of antiphospholipid syndrome (APS) our understanding of molecular mechanisms of living matter has become more sophisticated and on this way monocytes has become crucial player, particularly in pathogenesis of APS. Thrombotic and non-thrombotic complications of APS could be explained by monocytes' activation too. But mechanisms underlying their activation are poorly investigated. So we aimed to determine transcriptional activity of monocytes after exposing them to low concentrations of lipopolysaccharide (LPS) and LPS+ATP using comparative of RT-PCR. Our study included eleven women suffering from recurrent miscarriages and APS (mean age 30±5,6 years). Nine healthy women (mean age of 29±8,5 years) without a positive family history of APS, autoimmune diseases and thrombosis were chosen as a control group. The results showed increasing levels of TLR2, IL-23, CCL2, CXCL10, IL-1β and IL-6 in APS cells, while in healthy cells LPS resulted in IL-6 and STAT3 elevated mRNAs. Double stimulation of APS cells resulted in decreased mRNA levels of CCL-2, IL-1β, and mRNA NLRP3 in healthy cells. At the same time TLR2 mRNAs were elevated in both groups after double stimulation. Thus increased sensitivity of APS cells to LPS may contribute to thrombus formation. Low concentration of ATP diminishes LPS-induced inflammatory state of APS monocytes, which might be one of potential regulatory mechanisms.
