Nature of Peptide/Cargo | Nociceptive responses to various noxious stimuli are inhibited or abolished in capsaicin-treated animals. This effect is presumed to arise from the toxic action of capsaicin and the consequent neurodegeneration of C-fibre nociceptors. |
Mechanism | Neurodegeneration of C-fibre nociceptors |
Cargo Sequence/Structure | None |
Name of cargo
| Not applicable |
Assay | Pain response evaluated by a visual analogue scale |
Enhancer | None |
Properties of enhancer | Not applicable |
Concentration | 50 µl containing 50 nmol of capsaicin |
Incubation time | 5-7 consecutive days |
Tissue permeability (value with units) | Capsaicin (50 nmol, 50 µl) produced a remarkable pain response (considered as 100 in the VAS), sneezing and secretion of copious flow of nasal fluid. Capsaicin applications were performed every day for 5-7 days until the painful response reported by each subject was reduced by about 80% |
