Cell death via necrosis and apoptosis is a hallmark of deep dermal to full-thickness cutaneous burn injuries. Keratinocytes might act as thermosensory cells that transmit information regarding ambient temperature via heat-gated transient receptor potential vanilloid (TRPV) ion channels. The aim of this study was to investigate the distribution of TRPV1, 2, 3, and 4 in uninjured and thermally burned skin. The authors investigated warmth-evoked currents in keratinocytes and cell kinetics of thermally injured keratinocytes in culture with agonists and antagonists of TRPV channels. Specimens of uninjured normal skin and discarded tissue of thermally injured skin were stained for TRPV1, 2, 3, and 4. Cultured primary human keratinocytes were heated for 5 minutes at the following temperatures: 37°C (control), 42°C, and 60°C and thereafter cultured for 24 or 48 hours at 37°C. Thermally stressed cells were treated with TRPV antagonists capsazepine or ruthenium red, and cell viability capacity was determined. TRPV1, TRPV2, TRPV3, and TRPV4 immunoreactivity was differentially identified on basal and suprabasal keratinocytes of healthy human skin. Patch clamp analysis showed a functional response of human keratinocytes at temperatures >40°C. Cell death of keratinocytes after heating at 42°C was reduced by 15 and 5% with ruthenium red and by 20 and 30% by capsazepine at 24 and 48 hours, respectively. Cell death after treatment at 60°C was significantly reduced at 24 hours with capsazepine (22%) or ruthenium red (18%) but only minimally affected after 48 hours postinjury. Interaction with TRPV channels on keratinocytes may offer a new strategy to counteract cell death after thermal injury.
