Regulated Cell Death in Traumatic Brain Injury: Investigating Mechanisms Contributing to Cognitive Impairment

Area of Science:

• Neuroscience
• Cell Biology
• Pathology

Background:

• Traumatic brain injury (TBI) frequently results in debilitating cognitive impairment.
• Limited effective treatments exist for post-TBI cognitive decline.
• Regulated cell death (RCD) is increasingly recognized as a key mechanism of neuronal loss following TBI.

Purpose of the Study:

• To review the molecular mechanisms of major RCD pathways implicated in TBI.
• To critically assess the therapeutic potential of targeting RCD in TBI.
• To explore the complex interplay of RCD pathways in cognitive impairment after TBI.

Main Methods:

• Systematic review of recent scientific literature.
• Analysis of molecular mechanisms of apoptosis, necroptosis, pyroptosis, ferroptosis, and cuproptosis.
• Evaluation of therapeutic strategies targeting RCD pathways.

Main Results:

• Five major RCD pathways (apoptosis, necroptosis, pyroptosis, ferroptosis, cuproptosis) contribute to neuronal damage and cognitive deficits post-TBI.
• Targeting these RCD pathways demonstrates significant therapeutic potential for mitigating cognitive impairment.
• The interplay between different RCD pathways is complex and crucial in the context of TBI.

Conclusions:

• Targeting specific RCD pathways represents a promising and precise therapeutic approach for post-TBI cognitive impairment.
• Further research is needed to address challenges in combination therapies and effective brain delivery systems.
• Modulating RCD offers a novel strategy to enhance neuroprotection and improve quality of life after TBI.
