Thromboinflammation is a peculiar and key component of acute COVID-19 pathogenesis, which contributes to long COVID. In a recent study, Ryu et al. demonstrate that the SARS-CoV-2 spike protein interacts with fibrinogen, promoting fibrin polymerization and its inflammatory activity. Targeting the inflammatory fibrin peptide protected mice from spike-dependent fibrin clotting and neuropathology.

Subretinal injection of adeno-associated virus (AAV) is generally more efficacious and less inflammatory than intravitreal injection for retinal gene therapy. However, adverse events (e.g.

Pterygium is a common ocular surface lesion, and postoperative recurrence remains a major challenge due to insufficient therapeutic strategies targeting fibroblast proliferation and inflammation. Fibrinogen hydrogel (Fibrin glue, FG), a bioadhesive hydrogel, is widely used in pterygium surgery to secure conjunctival autografts. However, its low adhesion often leads to graft detachment, hindering effective repair.

Platelets in peripheral blood critically drive clot formation in health and disease. Previously considered to uniformly respond to vascular injury and inflammatory cues, recent studies have highlighted that circulating platelets exhibit marked heterogeneity, with distinct populations contributing differentially to hemostasis, thrombosis, and inflammation. In this Review, we highlight platelet diversity as a consequence of origin (i.

Objective: Cardiovascular events are major determinants of morbidity and mortality in systemic lupus erythematosus (SLE), particularly in patients with renal involvement. While oxidative stress has been implicated in driving vascular and renal damage in SLE, the specific mechanisms remain unclear. This study investigated the potential role of oxidative stress-induced alterations in fibrinogen structure and function in the pathogenesis of atherothrombosis in SLE.

Severe COVID-19 is characterized by immune-coagulation dysregulation, yet the contribution of related autoantibodies remains poorly understood. We investigated relationships between plasma autoantibody reactivities, whole-blood transcriptomics, plasma proteomics, and clinical laboratory parameters in a cohort of hospitalized COVID-19 patients. Transcriptomic analysis revealed that 42 curated coagulation and complement cascade genes were upregulated in severe cases compared to healthy controls, with 15 genes, including CR1L, ELANE, ITGA2B, ITGB3, VWF, TFPI, PROS1, MMRN1, and SELP (> 1.
