Embodiments of the technology described herein are based upon the discoveries that neutrophil extracellular traps (NETs) provide a stimulus for thrombus formation and that NETs are present in stored blood products. Accordingly, some embodiments relate to methods of treating and preventing toxicity of NETs and thrombosis caused by NETs. Additional embodiments are directed towards methods of treating stored blood products to prevent transfusion-related injuries.

Methods for treating and preventing neutrophil-derived net toxicity and thrombosis

The methods described herein include methods for the treatment of subjects who have Clonal Hematopoiesis of Indeterminate Potential (CHIP) or a Philadelphia-negative myeloproliferative neoplasm (MPN), e.g., polycythaemia vera (PV) or essential thrombocythaemia (ET), using inhibitors of JAK-STAT signaling.

Inhibition of JAK-STAT signaling inhibits formation of neutrophil extracellular traps (NETs)

Embodiments of the technology described herein are based upon the discoveries that neturophil extracellular traps (NETs) provide a stimulus for thrombus formation and that NETs are present in stored blood products. Accordingly, some embodiments are directed towards methods of treating stored blood products to prevent transfusion-related injuries e.g., preventing transfusion-related acute lung injury (TRALI), by treating blood transfusion products with an anti-Neutrophil Extracellular Trap (NET) compound.
