The discovery of the NET network (neutrophil extracellular trap) has revolutionized the perception of defense mechanisms used by neutrophils in infections and non-infectious states, as this mechanism proves the complexity of the ways in which neutrophils can act in the organism. The paper describes the NET network and its participation in bacterial, viral, fungal and parasitic infections, both in a positive and a negative aspect. In addition, attention was paid to the participation of NETs in the course of autoimmune diseases, cancer, as well as its impact on pregnancy and fertility in mammals.

Objective: Rheumatoid arthritis (RA) is an autoimmune condition that causes severe joint deformities and impaired functionality, affecting the well-being and daily life of individuals. Consequently, there is a pressing demand for identifying viable therapeutic targets for treating RA. This study aimed to explore the molecular mechanisms of osteoclast differentiation in PBMC from patients with RA through transcriptome sequencing and bioinformatics analysis.

Platelets and neutrophils are among the most abundant cell types in peripheral blood. Beyond their traditional roles in thrombosis and haemostasis, they also play an active role in modulating immune responses. Current knowledge on the role of platelet-neutrophil interactions in the immune system has been rapidly expanding.

Delayed tooth extraction socket (TES) healing can cause failure of subsequent oral implantation and increase socioeconomic burden on patients. Excessive amounts of M1 macrophages, apoptotic neutrophils (ANs), and neutrophil extracellular traps (NETs) impair alveolar bone regeneration during TES healing. In the present study, we first discovered that conditioned medium (CM) collected from berberine-treated human bone marrow mesenchymal stem cells (BBR-HB-CM) accelerated TES healing.

Pediatric intensive care patients are particularly susceptible to severe bacterial infections because of ineffective neutrophil responses. The reasons why neutrophils of newborns are less responsive than those of adults are not clear. Because adenosine triphosphate (ATP) and adenosine (ADO) tightly regulate neutrophils, we studied whether the ATP and ADO levels in the blood of newborn mice could impair the function of their neutrophils.

Neutrophils play key protective roles in influenza infections, yet excessive neutrophilic inflammation is a hallmark of acute lung injury during severe infections. Phenotypic heterogeneity is increasingly recognized in neutrophil populations; however, how functional variation in neutrophils between individuals determine the diverse outcomes of influenza remains unclear. To examine immunologic responses that may drive varying outcomes in influenza, we infected C57BL/6 (B6) and A/J mice with mouse-adapted influenza A virus A/PR/8/34 H1N1.
