CPTCs Drive Somatic-Visceral Communication via the Wnt Axis in Somatic Mechanotherapy: A Single-Cell Deep Learning Study

Somatic mechanical stimulation (e.g., acupuncture) exerts systemic immunomodulatory effects, yet the cellular bridge translating peripheral physical force into visceral repair remains elusive. Here, employing a custom interpretable deep learning framework (CARSS) on single-cell RNA sequencing data, we identify CD34$^{+}$PDGFR$\alpha$$^{+}$ telocytes (CPTCs) as the primary mechanosensors in both fascia and colon during bacterial colitis. We show that somatic mechanotherapy triggers an AP-1/Hsp70-dependent transcriptional program in fascial CPTCs, inducing systemic Wnt elevation, which elicits a "transcriptional resonance" in colonic CPTCs, reprogramming their communication network from an inflammatory amplifier to a Wnt-driven regenerative hub. Mechanistically, this axis activates epithelial $\beta$-catenin/Myc signaling, suppressing apoptosis and restoring barrier integrity independent of immune cells. Our findings define a CPTC-Driven Mechano-Resonance Axis, where CPTCs serve as synchronized relay stations that convert local mechanical cues into systemic regenerative microenvironments.

Application of Single-cell Deep Learning in Elucidating the Mapping Relationship Between Visceral and Body Surface Inflammatory Patterns

As a system of integrated homeostasis, life is susceptible to disruptions by visceral inflammation, which can disturb internal environment equilibrium. The role of body-spread subcutaneous fascia (scFascia) in this process is poorly understood. In the rat model of Salmonella-induced dysentery, scRNA-seq of scFascia and deep-learning analysis revealed Warburg-like metabolic reprogramming in macrophages (MPs) with reduced citrate cycle activity. Cd34+/Pdgfra+ telocytes (CPTCs) regulated MPs differentiation and proliferation via Wnt/Fgf signal, suggesting a pathological crosstalk pattern in the scFascia, herein termed the fascia-visceral inflammatory crosstalk pattern (FVICP). PySCENIC analysis indicated increased activity transcription factors Fosl1, Nfkb2, and Atf4, modulated by CPTCs signaling to MPs, downregulating aerobic respiration and upregulating cell cycle, DNA replication, and transcription. This study highlights scFascia's role in immunomodulation and metabolic reprogramming during visceral inflammation, underscoring its function in systemic homeostasis.
