“…Transfusion-related acute lung injury is an immune-inflammatory lung disorder that shows its clinical symptoms within 6 to 72 h of blood administration, often remains undiagnosed, and is underreported because of a lack of awareness ( 23 ). This makes the diagnosis of this disease a challenging task in clinical settings.…”

Non-antibody-mediated transfusion-related acute lung injury (TRALI) may account for up to 25% of TRALI cases. This indicates the need for further research to understand the pathophysiological mechanisms involved beyond antibody mediation fully. During this research, a TRALI rat model was developed using the trauma-blood loss-massive transfusion method. The severity of pulmonary edema was checked via measurement of lung histopathological changes and the amount of Evans blue dye fluid and bronchoalveolar lavage fluid protein leakage. In addition, potential mechanisms of pathophysiological pathways and inflammation cascades were investigated in TRALI rats in vivo. The findings indicated that TRALI increased inflammatory cytokines and triggered elevated levels of high-mobility group box 1(HMGB1)/ receptor-interacting protein kinase 3 (RIP3), apoptosis protein, and mRNAs in the TM (TRALI Model) group as opposed to the normal control.Furthermore, TRALI activated the Toll-like receptor 4 (TLR4) / Nuclear Factor-Kappa B (NF-κB) and mitogen-activated protein kinase (MAPK)signaling pathways, which partially regulated the inflammatory response in the TRALI rats. A significant increase was observed in the inflammatory mediators HMGB1 and RIP3 during the early stages of TRALI, suggesting that these mediators could be used as diagnostic markers for TRALI. In addition, HMGB1 and RIP3 promoted the inflammatory response by stimulating the TLR4/NF-κB and MAPK signaling pathways in the lung tissue of rats. Identifying efficient agents from inflammatory mediators such as alarmin can be an innovative scheme for diagnosing and preventing TRALI. These findings give HMGB1 and RIP3 a strong theoretical and experimental foundation for clinical use.
