photodynamic

activated or made more powerful by light.

photodynamic agent
a substance that is activated by light to cause damage to tissue. It may be exogenous and absorbed preformed from the environment, or endogenous in that it is formed within the body as an abnormal metabolite, e.g. porphyrins, or as a normal metabolite, e.g. phylloerythrin, and accumulate in tissues because of faulty excretion, e.g. in hepatic disease.
photodynamic therapy
the use of photodynamic agents in the treatment of disease.

It was suggested that in PDT with HPD the hyperthermia produced by a laser irradiation could improve the tumour response to the therapy via inhibiting the repair of photodynamically induced injuries [32], an increase in the reactivity of the formed [sup.

In addition to increase of ROS production, more interestingly, photodynamically induced mitochondrial apoptosis induces signal transduction pathways, which also participate in the development of immune responses [86].
