ABSTRACT
Alveolar macrophages (AM) and monocytes (MO) are myeloid cells that play a substantial role in the development and establishment of the innate and adaptive immune response. These cells are crucial for host defense against various pathogens, but their role in malaria is poorly understood. Here, we characterize the dynamics of AMs and recruited leukocytes subpopulations in the airways during experimental Plasmodium berghei NK65-NY (PbNK65). We show that PbNK65 infection induces an increased pulmonary vascular permeability that provides Ly6Clow MOs, neutrophils (NEU), CD4+ and CD8+ lymphocytes in the airways. This inflammatory environment resulted in an increase in the population and alteration of the activation state of the AMs. Taken together, the data presented provide new insights into airway inflammation associated with pulmonary malaria.
