Understanding the signaling mechanisms in PDT may provide means to modulate the PDT effects at the molecular level and potentiate its antitumor effectiveness. An important phenomena that happens in the intracellular portion of signaling is signal amplification. During signal amplification, a few number of receptors are initially activated. The intracellular response results in multiple secondary messengers to be activated, thereby amplifying the initial signal. This book details our progress in understanding the receptor and intracellular signaling mechanisms utilized by semaphorins.
