Key Event Relationship Description
Cell death can help the maintenance of the organ, for example by avoiding cancer. However, in the KER, cell death will lead to necrotic tissue. If too many cells die, the tissue will fall apart.
There are several types of necrotic tissue caused by cell death:
Apoptosis (individual cell necrosis), spotty and focal necrosis, zonal necrosis confluent necrosis. Every type can have a different underlying disease. All types can occur by drug induced liver injury.(Krishna 2017).
Evidence Supporting this KER
It has been well established that cell death can lead to necrotic tissue.
(Guicciardi et al. 2013): Apoptosis and necrosis in the liver.
(Luedde et al. 2014): Cell death in liver disease.
