  "abstract": "Clinical immunity to malaria develops after repeated malaria episodes. In this process, the inflammatory response is modulated to respond less vigorously upon reinfection. Monocytes are a major source of proinflammatory mediators during blood-stage infection and are known to adapt to repeated pathogen exposure. Here, we investigated the effect of previous malaria exposure on monocytes during blood-stage malaria by comparing the response in previously exposed and primary infected individuals. We observed reduced levels of several proinflammatory chemokines in previously exposed individuals, linked to changes in monocytes. Similarly, BAFF levels were lower in these individuals and associated with modulation of monocyte and dendritic cells. This affected the BAFF/BAFF-R axis, crucial for B cell responses, correlating with increasing parasite-specific antibody levels. Collectively, we present insights into how previous malaria exposure shapes monocyte responses during acute malaria and how these, in turn, correlate with modulation of the B cell compartment and humoral immune response.",
