| Outline of Final Research Achievements |
Recently, non-equilibrium atmospheric pressure plasma (APP) emerged to exert diverse biological responses, though the underlying mechanisms remained to be determined. This study aimed to explore precise mechanisms underlying of plasma-inducible increases in intracellular Ca2+ concentration in insulin-responsive cells, which has been recently discovered by our research group. Our results demonstrated that increases in intracellular Ca2+ are induced by continuous low-dose O2－/ ONOO－ supply, which is mediated through TRP channel activation. Our findings indicate the potential of APP for regulating insulin-responsive cell functions. Moreover, APP showed inhibitory actions on adipogenic differentiation of 3T3L1 cells. Together, these results demonstrate that APP-induced TRP channel activation is intimately involved in various cellular responses triggered by APP exposure.
