Key Takeaway
Consider cytoskeleton-mediated autophagy regulation as a novel, yet unquantified, therapeutic strategy for neurodegeneration.

This publication is a narrative review rather than a primary trial or systematic analysis. Its scope focuses on the theoretical and mechanistic implications of cytoskeleton-mediated autophagy regulation within the fields of neurodegeneration and aging. The authors synthesize existing knowledge to propose that modulating this interaction axis could represent a promising avenue for future therapeutic development. No specific medications, dosages, or patient cohorts are detailed in this source.

The authors do not provide pooled effect sizes, p-values, or confidence intervals because the input data for such metrics are not reported. Consequently, the review offers qualitative conclusions regarding the potential utility of this biological target rather than statistical evidence of efficacy. The text explicitly notes that adverse events, tolerability, and discontinuation rates were not reported, which precludes any assessment of the safety profile for this specific mechanism.

Limitations acknowledged by the authors or inherent to the narrative format include the absence of reported study populations and sample sizes. The practice relevance is framed cautiously, suggesting that while targeting the cytoskeleton-autophagy interaction axis may offer novel strategies, the evidence remains conceptual. Clinicians should interpret these findings as a hypothesis for future research rather than established clinical guidance, given the lack of quantitative data and reported safety information.

This review systematically summarizes the central roles and molecular mechanisms of the cytoskeletal system—including actin filaments, microtubules (MT), intermediate filaments, and the Septin family—in the regulation of autophagy. The cytoskeleton not only provides a structural framework and facilitates transport for the autophagic process but also acts as a dynamic signaling hub, participating in every stage from autophagosome formation and cargo recognition to targeted trafficking and autophagosome-lysosome fusion. Actin filaments regulate the initiation of autophagy through dynamic assembly, Arp2/3-mediated nucleation, and mechanosensing. Microtubules drive the transport and localization of autophagosomes by relying on “dynamic instability” and the “tubulin code”. Intermediate filaments—such as vimentin—and septins influence autophagy flux by maintaining organelle integrity, forming molecular scaffolds, and establishing diffusion barriers on membranes. This review further discusses the functional implications of this regulatory network in diverse physiological and pathological neuroimmune contexts, including neurodegeneration and aging. Finally, we highlight that targeting the cytoskeleton–autophagy interaction axis may offer novel therapeutic strategies for related diseases.
