Circulating Monocytes, Tissue Macrophages, and Malaria
Table 1
Diverse cell types mediate malaria-induced immune response and injury.
Cell type
Location
Function
Kupffer cell
Liver
(i) Phagocytosis of infected RBCs (ii) Recruitment of other immune cells by secretion of cytokines (iii) Prevention of parasitic infection in hepatocytes (iv) Limiting infection through induction of apoptosis
Splenic macrophages
Spleen
(i) Secretion of cytokines
Circulating monocytes
Blood
(ii) Phagocytosis of infected RBCs
Microglia
CNS
(i) Induce accumulation of perivascular macrophages (ii) Secretion of cytokines
Hofbauer cells (fetal)
Placenta
(i) Phagocytosis of infected RBCs (ii) Secretion of cytokines (iii) Interaction between maternal/fetal immunity
Intervillous monocytes (maternal)
Decidual macrophages (maternal)
