We infected Mavs–/– mice (which produce both large amounts of early IFN‐α/β and late IL‐6) with N67C and treated them with anti‐IL6R antibodies at day three p.i. We found comparably low parasitemia levels and mortalities compared with control antibody‐treated Mavs–/– mice (Figure S3A,B, Supporting Information). This evidence concerns the gene IL6R and parasitic infectious disease.
