Transient Receptor Potential Vanilloid-1 in Epidermal Keratinocytes May Contribute to Acute Pain in Herpes Zoster
Bibliographic record
Abstract
The role of transient receptor potential vanilloid-1 (TRPV1) in the initiation of neurogenic inflammation and transduction of pain is well established. In this study 33 patients with herpes zoster (HZ) were recruited from a single centre and underwent a questionnaire interview at their first visit. Punch biopsies from the HZ lesions and the contralateral unaffected skin were performed to localize and quantify the expression of TRPV1. Immunofluorescent staining for TRPV1 was most prominent in the epidermal keratinocytes. Both TRPV1 mRNA and protein levels were significantly higher in the HZ epidermis than in control epidermis (relative ratio 1.62 ± 0.27, p = 0.033 and 2.55 ± 0.51, p = 0.005, respectively). Protein TRPV1 ratio (HZ lesion/control) correlated with the degree of pain (measured on a visual analogue scale; VAS) (p = 0.017) and was significantly lower in patients who had taken either HZ medication or painkillers prior to their visit. These results suggest that non-neuronal TRPV1 may contribute to acute pain in herpes zoster.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
