Regarding pH-sensitive liposomes, there are three mechanisms of drug delivery intracellularly, which occurs via endocytosis. This is possible because of the acidic environment within endosomes. The first mechanism is through the destabilization of the liposome within the endosome, triggering pore formation on the endosomal membrane and allowing diffusion of the liposome and its contents into the cytoplasm. Another is the release of the encapsulated content within the endosome, eventually diffusing out into the cytoplasm through the endosomal membrane. Lastly, the membrane of the liposome and the endosome fuse together, releasing the encapsulated contents onto the cytoplasm and avoiding degradation at the lysosomal level due to minimal contact time.
