MPO and infection: Neutrophils were suggested to be permissive to ZIKV as viral RNA was found in myeloperoxidase+ neutrophils present in the lymph nodes of cynomolgus monkeys 7 days post-infection (10) and in CD45+CD11b+ neutrophil-myeloid cells in the placenta of AIR mice (vertical transmission model in a Rag1-deficient mouse) (26).
