It is still a question of debate whether neutrophils, often found in the tumor microenvironment, mediate tumor-promoting or rather tumor-inhibiting activities. The present study focuses on the involvement of neutrophils in high grade serous ovarian cancer (HGSOC). Macroscopic features classify two types of peritoneal tumor spread in HGSOC. Widespread and millet sized lesions characterize the miliary type, while non-miliary metastases are larger and associated with better prognosis. Multi-omics and FACS data were generated from ascites samples. Integrated data analysis demonstrates a significant increase of neutrophil extracellular trap (NET)-associated molecules in non-miliary ascites samples. A co-association network analysis performed with the ascites data further revealed a striking correlation between NETosis-associated metabolites and several eicosanoids. The congruence of data generated from primary neutrophils with ascites analyses indicates the predominance of NADPH oxidase 2 (NOX)-independent NETosis. NETosis is associated with protein S100A8/A9 release. An increase of the S100A8/CRP abundance ratio was found to correlate with favorable survival of HGSOC patients. The analysis of additional five independent proteome studies with regard to S100A8/CRP ratios confirmed this observation. In conclusion, NET formation seems to relate with better cancer patient outcome.

Unlabelled: Methicillin-resistant (MRSA) is a leading cause of endovascular infections, where interactions with endothelial cells play a critical role in pathogenesis. Gp05, a prophage-encoded protein, has previously been implicated in promoting antibiotic persistence by modulating MRSA cellular physiology and evading neutrophil-mediated killing. In this study, we investigated the role of Gp05 in MRSA-endothelial cell interactions, focusing on its impact on bacterial adhesion, invasion, cytotoxicity, and the host inflammatory response.

Background: Burn injuries trigger complex immune responses and gene expression changes, impacting wound healing and systemic inflammation. Understanding these changes is crucial for identifying biomarkers and therapeutic targets.
Methods: We analyzed two GEO datasets (wound tissue (GSE8056) and blood (GSE37069)) to identify differentially expressed genes (DEGs) in burn injury samples versus controls.

Kaempferol (KMF) is a dietary flavonoid exhibiting profound immunomodulatory effects across multiple immune cell populations. This review synthesizes current insights into how KMF regulates diverse immune cell populations and its therapeutic potential in inflammatory and immune-related disorders. KMF exhibits multifaceted effects on T cells.

Deep vein thrombosis (DVT) and pulmonary embolism (PE) are key initiating events in the development of venous thromboembolism (VTE), a condition associated with significant morbidity, mortality, and long-term complications. While traditional therapies have focused on anticoagulation and thrombolysis, current evidence describes the pivotal role of immune pathways in the pathogenesis and progression of thrombosis. This review explores the multifaceted mechanisms underlying DVT and PE, emphasizing the contribution of inflammation, leukocyte activation, and immuno-thrombosis to thrombus formation and embolization.

Aneurysmal subarachnoid hemorrhage (aSAH) is a devastating neurological disease, and one of the primary drivers of morbidity after aneurysm rupture is the phenomenon of delayed cerebral ischemia (DCI). Significant knowledge has been gained over the past two decades of the impact of neuroinflammation in DCI; and neutrophils are now believed to play a major role. There is significant human subject data showing the rise of neutrophil related inflammatory markers and neutrophil's association with poor outcome after aSAH, but as of yet no trials involving human subjects have been done specifically targeting neutrophils.
