THE HYPOTHESIS. "The presence of bacteriophages in symbiotic bacteria that obligately reside in eukaryotes may promote eukaryotic DNA transfers to bacteriophages." https://lnkd.in/dYh3-r4 View in LinkedIn

APOPTOSIS #2. "The second purpose is the elimination of damaged cells, which may not be able to perform their function properly, or are potentially dangerous to the organism (for instance, cells with DNA damage which may lead to mutations)." https://celldeath.files.wordpress.com/2010/11/lopezself_munoz.pdf View in LinkedIn

TWO DOMAINS. "Therefore, phage WO appears to uniquely contend with the cellular exit, entry and defence mechanisms of two separate domains of life", namely the bacteria Wolbachia and the eukaryotic arthropod host. https://lnkd.in/dG3vir9 View in LinkedIn

APOPTOSIS #1. "The first one is the removal of cells which are no longer necessary, such as cells which played a role during development but are not needed in the adult, or immune cells after the pathogen has been cleared." https://celldeath.files.wordpress.com/2010/11/lopezself_munoz.pdf View in LinkedIn

LYTIC PHASE. "Electron microscopy and quantitative analyses indicate that prophages undergo a lytic phase capable of rupturing bacterial and eukaryotic cell membranes, and phage WO occurs in the extracellular matrix of arthropod gonads." https://lnkd.in/dG3vir9 View in LinkedIn

CONSERVED AND ADAPTED. "The ancient and deeply conserved genetic and molecular pathways that cause cell death indicate that death-promoting mechanisms show less variability than would be expected for unavoidable or maladaptive death.” View in LinkedIn

INTERNAL REAPER. "There is substantial evidence that cell death is often internally controlled and regulated in unicellular organisms." View in LinkedIn

PROGRAMMED CELL DEATH "seems paradoxical, however, in cases where the single cell is the entire organism. In some species ambiguity arises as to whether cells are organisms or parts of organisms." View in LinkedIn
