Abstract:
Traumatic brain injury (TBI), a major global public health burden, is characterized by complex pathophysiology involving primary and secondary injuries, with programmed cell death (PCD) pathways significantly impacting neuronal damage and neurological dysfunction. Substantial evidence over time highlights necroptosis-a caspase-independent, inflammatory form of PCD mediated by RIPK1/RIPK3/MLKL-as a key driver of secondary injury after TBI. However, the dynamic interplay between necroptosis and other PCD pathways after TBI remains poorly understood. In this review, we systematically describe the mechanisms involving necroptosis in TBI and its potential therapeutic targets, while delving into the interplay and regulatory relationships between necroptosis and other PCD pathways, including apoptosis, autophagy, pyroptosis, and ferroptosis. Future investigations and the formulation of therapeutic approaches for TBI should comprehensively consider the complex characteristics of necroptosis and its interplay with other pathways.

Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

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 20th century...
