Influence of intracellular pH on character of mice peritoneal macrophage response to red light irradiation

: It was detected that exposure of macrophages to red light (600-740 nm) led to the changes in their intracellular pH and hydrolytic activity. The character of these changes depends on the initial level of pH in the cells. The maximum effect of irradiation is detected if the initial pH level is low. It is possible that Na/H-exchanger takes part in normalizing effect of red light on intracellular pH level.
