Platelets have a well-recognized role in hemostasis and thrombosis, and they are important amplifiers of inflammation and innate immune responses. The formation of DNA extracellular traps (ETs) is a complex cellular mechanism, which occurs in response to microbial infections and sterile inflammation, and results in the release of DNA complexed with histones and various granular proteins. ETs were first discovered in neutrophils (NETs); however, it is now accepted that other leukocytes, including eosinophils (EETs) and monocytes/macrophages (MoETs/METs), can also generate them. Moreover, several types of ETs have been described.Increasing evidence has demonstrated that platelets modulate the formation of ETs. This review summarizes recent findings about the physiopathological role of platelets in the formation of ETs during infection and future perspectives in the field.

Background: Acute ischemic stroke treatment typically involves tissue-type plasminogen activator (tPA) or tenecteplase, but about 50% of patients do not achieve successful reperfusion. The causes of tPA resistance, influenced by thrombus composition and timing, are not fully clear. Neutrophil extracellular traps (NETs), associated with poor outcomes and reperfusion resistance, contribute to thrombosis.

Objective: This study evaluated the diagnostic value of plasma Neutrophil extracellular traps (NETs) levels and the index of cardiac electrophysiological balance (iCEB) in identifying silent myocardial ischemia (SMI) in maintenance hemodialysis (MHD) patients.
Methods: This cross-sectional observational study involved patients receiving MHD treatment. Data were collected on coronary angiography performed in our hospital from February 2023 to February 2024.
The methyl-CpG binding domain 2 regulates peptidylarginine deiminase 4 expression and promotes neutrophil extracellular trap formation via the Janus kinase 2 signaling pathway in experimental severe asthma.

Objective: The prognosis for severe asthma is poor, and the current treatment options are limited. The methyl-CpG binding domain protein 2 (MBD2) participates in neutrophil-mediated severe asthma through epigenetic regulation. Neutrophil extracellular traps (NETs) play a critical role in the pathogenesis of severe asthma.

To investigate the potential mechanisms underlying neutrophil extracellular traps (NETs) confer ferroptosis resistance and CD8(+) T cell inhibition in lung adenocarcinoma (LUAD). By the intravenous injection of LLC cells into the tail vein, a LUAD mouse model was created. Phorbol-12-myristate-13-acetate (PMA) stimulated neutrophils to facilitate NETs formation and combined with NETs inhibitor DNase I to explore NETs mechanism on LLC cell proliferation, migration, ferroptosis resistance, and CD8(+) T cell activity.

Background: Ischemia-reperfusion injury (IRI) often results in renal impairment. While the presence of neutrophil extracellular traps (NETs) is consistently observed, their specific impact on IRI is not yet defined. Sivelestat sodium, an inhibitor of neutrophil elastase which is crucial for NET formation, may offer a therapeutic approach to renal IRI, warranting further research.
