Possible molecular effect related to the reception of low-intensity IR radiation: Role of Src-kinase

详细

The patch-clamp technique has been used to demonstrate that low-intensity IR irradiation affects the effective charge of the activation gating system of slow sodium channels in the nociceptive neuron membrane. IR photons are absorbed by ATP molecules bound to Na⁺,K⁺-ATPase at their hydrolysis site. Na⁺,K⁺-ATPase is a transducer of signal that is further delivered to slow sodium channels and cell genome. It is demonstrated that the irradiation does not modulate the response of a sensory neuron in the presence of PP2, an inhibitor of Src-kinase. The results show that Src-kinase is a series unit involved in the intracellular cascade processes triggered by low-intensity radiation of CO₂ laser.
