CCR3 and Increased total eosinophil count: Our in vitro assays indicate that arginase- and RELMα-producing WT BmL3AAMφ do not affect larval viability in isolation and our adoptive transfer experiments into SCID recipients further indicate that arginase- and RELMα-producing WT BmL3AAMφ do not affect B. malayi larval survival if CCR3 expressing cells and eosinophilia is effectively ablated.
