However, there is a notable lack of therapeutic drugs for chemotherapy-induced neuropathic pain (CINP).

Celastrol (0.5, 1.0, and 2.0 mg/kg, intraperitoneal injection) was administered to assess its therapeutic effects on vincristine-induced neuropathic pain (VINP). Transmission electron microscopy (TEM) was employed to examine damage to the sciatic nerve fibers and mitochondria.

Concurrently, celastrol modulates the production of reactive oxygen species (ROS) and the expression of apoptosis-related proteins (Cleaved Caspase-3, Bax, and Bcl-2) by suppressing the phosphorylation of CaMKII in astrocytes, thereby ameliorating the mitochondrial damage and cell apoptosis caused by VCR.</p><p><strong>Conclusion: </strong>Our findings reveal that celastrol exerts therapeutic effects on VINP through its antiinflammatory, antioxidant, and anti-apoptotic properties.
