Feeding macrophages with apoptotic neutrophils increases the efficiency of macrophage‐based cell therapies in Schistosoma mansoni infection. Macrophages fed with apoptotic neutrophils (aN), apoptotic thymocytes (aT), or apoptotic hepatocytes (aH) and then stimulated with interleukin (IL)‐4, acquire in vitro distinct transcriptomic profiles depending on the type of apoptotic cell engulfed. Expression of genes like Chil3 and Rentla is potentiated only when IL‐4‐activated macrophages engulf aN, Socs2 and Cd274 are induced upon uptake of aH, and Serpinb9b and Cd274 upon phagocytosis of aH. Uptake of aN is mediated by the engagement of the receptor tyrosine kinases AXL and MERTK. In vivo, only the adoptive transfer of aN‐fed macrophages, but not aT or aH‐fed macrophages, reduces parasitic egg load in the colon of S. mansoni‐infected mice.
