Inhibition of interleukin-1β reduces myelofibrosis and osteosclerosis in mice with JAK2-V617F driven myeloproliferative neoplasm

Inflammatory cytokines are elevated in patients with myeloproliferative neoplasms (MPN). Here the authors show that the JAK2-V617F mutation is associated with increased expression of IL-1 in MPN patients and that loss of IL-1β in JAK2-V617F mutant hematopoietic cells reduces MPN symptoms and myelofibrosis in a mouse model.
