IL6 and malaria: We treated YM infected‐Mavs–/– mice with IL‐6 at day three p.i. and found that the treatment markedly increased the mice parasitemia levels and resulted in a 100% death percentage, while BSA control‐treated mice survived (Figure 7A,B), suggesting that a late IL‐6 treatment markedly inhibits the anti‐malaria immunity against YM infections.
