Key messages

Cultured osteoclasts were susceptible to DV infection. Osteoclasts produced similar amounts of cytokines and infectious virions as macrophages. DV induced nuclear translocation of NFATc1 in osteoclast via CLEC5A. DV caused transient inflammatory reaction in bone tissue and upregulated osteolytic activity. Antagonistic anti-CLEC5A mAb inhibited DV-activated osteolytic activity in vivo.
