Neutrophil Extracellular Traps (NETs) represent the networks consisting of DNA, histones, and proteins produced by activated neutrophils. Such structures have been proved to play a crucial role in inducing neutrophil innate immune response in the pathogenesis of such autoimmune conditions as systemic lupus erythematosus, rheumatoid arthritis, psoriasis, as well as in the pathogenesis of other non-infectious processes, e. g., clotting disorders, thrombosis, diabetes, atherosclerosis, vasculitis and oncology diseases. Recent studies on animal models and human pathologies have uncovered a tremendous role for NETs in tumor progression and metastasis. In this regard, NETs should be considered as pro-oncogenic substances, which further investigation will provide an opportunity to develop new therapeutic strategies.

The article presents the results of the assessment of the role of platelets in formation of extracellular traps by neutrophils. We have detected the ability of platelets to oppress the formation of extracellular traps by neutrophils in vitro cultures in patients with rheumatoid arthritis (RA) (n = 42) and systemic lupus erythematosus (SLE) (n = 24), but not in patients with hemorrhagic vasculitis (GW) (n = 15). The study has revealed the interrelation of NETosis and rheumatoid factor in patients with RA and SLE, as well as NET formation and number of platelets in patients with GW.

AbstractDespite the advances made in the management of pregnancies in women with systemic lupus erythematosus (SLE), the rate of adverse pregnancy outcomes is still higher than that in the general population. In the last few years, neutrophil extracellular traps (NETs) were proven to be detrimental in both autoimmune diseases and placental injury. We investigated whether NETs could be detected in the placentas of pregnant individuals with SLE and explored the relationship between NETs and decidual natural killer cells (dNKs), which comprise the majority of immune cells at the maternal–fetal interface, using clinical samples and animal models. In this study, we found that the infiltration of NETs and dNKs, especially CD56+CD16+ NK cells, was significantly increased in pregnant individuals with SLE with placental insufficiency. In the murine models of SLE, the number of dNKs was significantly decreased due to the decreased formation of NETs affected by Ly6G. Moreover, the histopathological placental injury was reduced, with a remarkable increase in fetal birth weight. This study shows that NETs may contribute to immunological disorder in the placenta and the pathological changes in pregnancies with SLE, which provides a research basis for further explorations of the mechanism of SLE in placental impairment.
