Cellular Injury

by Richard Mitchell, MD, PhD

Cellular injury describes the stress-induced changes that a cell undergoes secondary to internal or external insults. There are thousands of ways a cell might be injured, but each of these etiologies culminates in a common cascade of cellular injury, starting with depletion of cellular ATP, followed by cell membrane permeabilization and biochemical pathway disruption, and culminating in irreversible DNA damage. Cell damage can be reversible or irreversible, depending on what step of the process has already occurred. Also, depending on the extent of injury, the cellular response may be adaptive and, where possible, homeostasis is restored. When injury severity exceeds the cell’s self-repair mechanisms, cell death occurs, either by necrosis or apoptosis.
