摘要

The recent study by Gao et al. (Apoptosis, 2025. https://doi.org/10.1007/s10495-025-02194-x) proposes a compelling paradigm in which a positive feedback loop between glycolysis and nucleus pulposus cell pyroptosis acts as a central driver of intervertebral disc degeneration. Their work provides a crucial mechanistic link between dysregulated metabolism and inflammatory cell death, building upon long-standing observations of lactic acid accumulation and cellular demise in the degenerative disc. While this refined model represents a significant conceptual advance, our commentary identifies several layers of complexity that must be addressed for therapeutic translation. We argue that the proposed cycle operates within a highly specific pathophysiological context, with key concerns including the model’s applicability across the disc’s spatial heterogeneities, potential pathway redundancy upon therapeutic inhibition, and unresolved upstream instigators of the glycolytic shift. Future research must move beyond in vitro models to focus on spatially resolved mapping in human specimens, combinatorial therapeutic strategies, and elucidating the prime movers—mechanical, age-related, or senescent in origin—that initiate this vicious cycle.
