And the zombie cell-killing drugs didn’t seem to slow bone loss; it just improved bone creation rates. ... This research was the clinical trial to test a zombie cell-killer treatment in humans ...
As they build up in your body, studies suggest, they promote aging and the conditions that come with it like osteoporosis and Alzheimer's disease. Basically the goal is to fight aging itself ...
The most notable components of the cell that are targets of cell damage are the DNA and the cell membrane. DNA damage: In human cells, both normal metabolic activities and environmental factors such as ultraviolet light and other radiations can cause DNA damage, resulting in as many as one million individual molecular lesions per cell per day.

In humans, PCD in progenitor cells starts at gestational week 7 and remains until the first trimester. [28] This process of cell death has been identified in the germinal areas of the cerebral cortex, cerebellum, thalamus, brainstem, and spinal cord among other regions. [27] At gestational weeks 19–23, PCD is observed in post-mitotic cells. [29]

Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
Embryonic stem cells and germ cells have also been described as immortal. [8] [9] Immortal cell lines of cancer cells can be created by induction of oncogenes or loss of tumor suppressor genes. One way to induce immortality is through viral-mediated induction of the large T-antigen, [10] commonly introduced through simian virus 40 (SV-40). [11]
Biological warfare, also known as germ warfare, is the use of biological toxins or infectious agents such as bacteria, viruses, insects, and fungi with the intent to kill, harm or incapacitate humans, animals or plants as an act of war. [1]
