Even after the initial cause of the necrosis has been halted, the necrotic tissue will remain in the body. The body's immune response to apoptosis, which involves the automatic breaking down and recycling of cellular material, is not triggered by necrotic cell death due to the apoptotic pathway being disabled.

Fusobacterium spp. and anaerobic spirochetes are often the cause of acute necrotizing ulcerative gingivitis (or Vincent's angina) which is a distinct form of ulcerative gingivitis. Deep neck infections that develop as a consequence of oral, dental and pharyngeal infections are generally polymicrobial in nature.
Cellulitis occurred in about 21.2 million people in 2015. [7] In the United States about 2 of every 1,000 people per year have a case affecting the lower leg. [1] Cellulitis in 2015 resulted in about 16,900 deaths worldwide. [8] In the United Kingdom, cellulitis was the reason for 1.6% of admissions to a hospital. [6]
Necrotizing fasciitis (NF), also known as flesh-eating disease, is an infection that kills the body's soft tissue. [3] It is a serious disease that begins and spreads quickly. [ 3 ] Symptoms include red or purple or black skin, swelling, severe pain, fever , and vomiting. [ 3 ]
Due to excitotoxicity, hypoxic death of cells within the central nervous system can result in liquefactive necrosis. [1] This is a process in which lysosomes turn tissues into pus as a result of lysosomal release of digestive enzymes. Loss of tissue architecture means that the tissue can be liquefied.
A skin infection is an infection of the skin in humans and other animals, that can also affect the associated soft tissues such as loose connective tissue and mucous membranes. [ citation needed ] They comprise a category of infections termed skin and skin structure infections (SSSIs), or skin and soft tissue infections (SSTIs), [ 1 ] and acute ...
A company called Tomorrow Biostasis is focusing on human cryopreservation in the hopes it can eventually reverse death. The new Berlin startup has already preserved the bodies of about 10 deceased ...
Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors. Cell damage can be reversible or irreversible.
