Corpse Engulfment Generates a Molecular Memory that Primes the Macrophage Inflammatory Response
Macrophages are multifunctional cells that perform diverse roles in health and disease. Emerging evidence has suggested that these innate immune cells might also be capable of developing immunological memory, a trait previously associated with the adaptive system alone. While recent studies have focused on the dramatic macrophage reprogramming that follows infection and protects against seconda...
متن کاملMacrophage-mediated corpse engulfment is required for normal Drosophila CNS morphogenesis.
Cell death plays an essential role in development, and the removal of cell corpses presents an important challenge for the developing organism. Macrophages are largely responsible for the clearance of cell corpses in Drosophila melanogaster and mammalian systems. We have examined the developmental requirement for macrophages in Drosophila and find that macrophage function is essential for centr...
متن کاملCED-1 Is a Transmembrane Receptor that Mediates Cell Corpse Engulfment in C. elegans
We cloned the C. elegans gene ced-1, which is required for the engulfment of cells undergoing programmed cell death. ced-1 encodes a transmembrane protein similar to human SREC (Scavenger Receptor from Endothelial Cells). We showed that ced-1 is expressed in and functions in engulfing cells. The CED-1 protein localizes to cell membranes and clusters around neighboring cell corpses. CED-1 failed...
متن کاملThe Dynami(n)cs of cell corpse engulfment.
Engulfment of dying cells plays an important role during animal development and homeostasis, and several proteins involved in this process are known. However, the cell biology underlying phagocyte arm extension and cell corpse degradation is not well understood. A study published in this issue of Developmental Cell (Yu et al., 2006) now demonstrates an important role for the GTPase dynamin in t...
متن کاملThe C. elegans Cell Corpse Engulfment Gene ced-7 Encodes a Protein Similar to ABC Transporters
The C. elegans gene ced-7 functions in the engulfment of cell corpses during programmed cell death. We report that the CED-7 protein has sequence similarity to ABC transporters, is broadly expressed during embryogenesis, and is localized to the plasma membrane. Mosaic analysis revealed that ced-7 functions in both dying cells and engulfing cells during the engulfment process. We propose that CE...
