CCR6 and malaria: Considering the importance of all these cell CCR6+ subsets in the malaria immunity8,9,10,11 and the early lethality presented by C57BL/6 wild-type (WT) mice challenged with Plasmodium berghei NK65 (PbNK65),9,12,13,14,15,16,17,18 we hypothesized that CCR6 KO mice could be even lesser resistant than WT mice to this parasite.
