Antimicrobial Photodynamic Therapy: Latest Developments with a Focus on Combinatory Strategies
6.2. Photochemical Internalization (PCI)
PCI may be used to enhance cell internalization of diverse macromolecules. It con- sists of PDT-induced disruption of endocytic vesicles and lysosomes improving the re- lease of their payloads into the cytoplasm of target cells. Although most PCI applications relate to cancer treatments, PCI could be extended to treat intracellular infections by de- livering antimicrobials into infected cells. For instance, Zhang et al. reported PCI as an antibiotic delivery strategy allowing to enhance cytoplasmic release of Gentamicin, to counter intracellular staphylococcal infection in eukaryotic cells and in zebrafish embryos.
