Abstract:
Trauma-induced cell death modalities, which serve as the initiating events of systemic inflammation and multi-organ dysfunction, have emerged as a pivotal focus in trauma pathology research. After trauma, the activation of distinct programmed cell death pathways exhibits a phased progression and intricate crosstalk, involving multi-tiered regulatory mechanisms such as mitochondrial pathway activation, inflammasome assembly, lipid peroxidation cascades, and dysregulated metal ion homeostasis. Notably, apoptosis, pyroptosis, necroptosis, and ferroptosis successively dominate inflammatory and metabolic dysregulation over time, while PANoptosis, as an integrated cell death program, demonstrates cross-pathway signal convergence. Emerging cell death paradigms further elucidate the complex interplay among mitochondrial stress, metal homeostasis, metabolic reprogramming, and trauma pathology. This review synthesizes the dual roles and therapeutic potential of these cell death modalities in tissue repair, aiming to provide a theoretical framework and intervention targets for the precise modulation of post-traumatic pathological responses.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
