Endoplasmic Reticulum Stress in Spinal Cord Injury: Pathological Roles, Molecular Targets, and Emerging Treatments: A...

Area of Science:

• Neuroscience
• Cellular Biology
• Biochemistry

Background:

• Spinal cord injuries (SCI) impose substantial physical and economic burdens.
• Molecular and cellular interactions, particularly endoplasmic reticulum (ER) stress and the unfolded protein response (UPR), significantly contribute to SCI progression.
• ER stress is implicated in neuronal degeneration and apoptosis following SCI.

Purpose of the Study:

• To systematically review the molecular pathways involved in ER stress in SCI pathogenesis.
• To investigate the roles of the ATF6-mediated apoptosis pathway and CHOP in SCI.
• To explore therapeutic strategies targeting ER stress for SCI treatment and prevention.

Main Methods:

• Systematic review of literature on ER stress, UPR, ATF6, and CHOP in SCI.
• Analysis of molecular and cellular mechanisms underlying ER stress-induced neuronal damage.
• Evaluation of genetic and pharmacological interventions targeting ER stress pathways.

Main Results:

• Prolonged ER stress exacerbates neuronal degeneration and apoptosis in SCI.
• The ATF6-mediated apoptosis pathway and CHOP are key players in SCI pathogenesis.
• Inhibiting ER stress pathways shows potential for preventing SCI-related degeneration and enhancing neuronal survival.

Conclusions:

• Targeting ER stress pathways is a promising therapeutic strategy for SCI.
• Pharmacological and genetic interventions mitigating ER stress can reduce neuronal damage and promote recovery.
• Complementary strategies like metabolic health maintenance and physical activity may further fortify the spinal cord against ER stress.
