cytoplasm to electron-dense state with loss of ribosomes from RER,
and prominent heterophagic elimination;
Type 2 — autophagic cell death with some nuclear changes; cell membrane
changes; abundant autophagocytotic vacuoles with dilatation
of ER, mitochondria, and Golgi; and inconsistent and late
heterophagic disposal;
Type 3A — nonlysosomal disintegration
