IL10 and infection: The balance between pro- and anti-inflammatory cytokines is consistent with the induction of the regulation of the immune response against P. vivax malaria and it has been confirmed by an increase in the number of Treg CD25+ cells during infection [15] and detection of high IL-10 levels in asymptomatic P. vivax malaria [5], indicating that the control was effective without provoking an imbalance of pro- or anti-inflammatory cytokines.
