- <p>This work provides a comprehensive, in-depth critique of the study by Shi, Reddy, Marrin <em>et al</em>., titled “<strong><em>Properties and functions of transcriptionally distinct enteric neurons</em></strong>” (<em>Cell</em>, 2025). The commentary systematically evaluates the conceptual, methodological, analytical and interpretive dimensions of the paper, which proposes a new molecular taxonomy of enteric neurons based on single-cell transcriptomics integrated with anatomical, physiological and behavioral data. Given the study’s broad implications for enteric neurobiology, gut–brain axis research and potential therapeutic development, a rigorous and transparent examination of its claims is essential for accurate interpretation and future research directions.</p> <p>Across structured sections, the commentary interrogates the sampling strategy, dissociation protocols, sequencing depth, batch integration, clustering robustness and differential expression analyses that underlie the proposed classification. It highlights how stress-induced transcriptional states, regional sampling imbalance and incomplete replicate documentation may confound cluster formation. The critique examines the limited specificity of marker gene validation, inconsistencies between in situ expression patterns and transcriptomic predictions, and the ambiguity introduced by relying on low-penetrance or state-dependent markers. It further evaluates the evidence for circuit-level organization presented via viral tracing, noting methodological constraints such as nonspecific labeling and sparse reconstruction.</p> <p>The analysis identifies multiple points where the original authors extrapolate functional or mechanistic conclusions beyond what the data support. Physiological and behavioral experiments, often underpowered or lacking precise targeting strategies, are discussed in relation to their capacity to validate transcriptional identity. Biological plausibility is assessed through comparison with established ENS developmental trajectories, neurochemical diversity and known anatomical constraints.</p> <p>The commentary concludes that while the study offers a valuable dataset and an ambitious vision for reorganizing ENS taxonomy, the evidence does not fully justify the proposed stable neuronal subtypes or their inferred physiological and translational roles. Recommendations for future research emphasize multimodal validation, longitudinal profiling, replicate-aware computational frameworks and integration of developmental, functional and contextual data.</p> <p>This Zenodo deposition provides an openly accessible, structured critique intended to support scientific transparency, reproducibility and constructive dialogue in the field of enteric neuroscience.</p>
