Spinal Cord Injury (SCI) presents a significant challenge in neuroscience and clinical medicine, often leading to severe and long-lasting disabilities. The secondary injury cascade, characterized by neuro-inflammation and oxidative stress, plays a critical role in exacerbating tissue damage post-trauma. In this context, natural compounds that can effectively mitigate these processes are of immense therapeutic interest. Caffeic Acid Phenethyl Ester (CAPE), a bioactive component of propolis, has emerged as a promising candidate, demonstrating significant effects in combating neuro-inflammation and oxidative stress, particularly in the context of SCI.

Research highlights the critical role of microglia in mediating neuro-inflammation following SCI. Activated microglia release a cascade of inflammatory mediators, including TNF-α, IL-1β, COX-2, and iNOS, which contribute to oxidative stress and neuronal damage. Studies investigating the caffeic acid phenethyl ester for spinal cord injury models have shown that CAPE can significantly reduce the production of these pro-inflammatory and oxidative stress-related proteins. This action directly addresses the detrimental secondary injury mechanisms.

The underlying CAPE mechanism of action in neuroprotection involves its interaction with key cellular signaling pathways. Notably, its ability to regulate the SIRT1/PGC1α/DRP1 axis is crucial. The SIRT1/PGC1α pathway is instrumental in maintaining cellular energy metabolism and antioxidant defense. By activating SIRT1 and subsequently PGC1α, CAPE helps to preserve mitochondrial function, reduce reactive oxygen species (ROS), and mitigate oxidative damage—processes that are severely compromised in SCI. This focus on the SIRT1/PGC1α/DRP1 pathway in SCI offers a detailed insight into CAPE's therapeutic potential.

The caffeic acid phenethyl ester neuroprotective effects extend to reducing neuronal loss and improving motor function recovery in SCI models. By dampening the inflammatory storm and oxidative insults, CAPE creates a more favorable environment for neuronal survival and regeneration. The caffeic acid phenethyl ester anti-inflammatory properties are thus directly translated into functional benefits for individuals affected by SCI.

As the scientific community continues to explore effective treatments for SCI, CAPE presents a compelling natural option. Its multifaceted actions, targeting both inflammation and oxidative stress through well-defined molecular pathways, make it a subject of intensive research.
