In contrast, for PBI cyclophanes with larger cavities guest encapsulation could efficiently modulate the photophysical properties to give highly fluorescent host guest complexes upon incorporation of electron-poor aromatic guest molecules or fully quenched systems upon incorporation of electron-rich molecules.
Technological resources are available for large-scale cell encapsulation intended for advanced therapies (gene therapy, somatic cell therapy and tissue engineering) in a cell factory, following GMP guidelines.
Within the Drosophila genus, there is large variation in encapsulation ability, from completely absent in some species to high in others.
The cellular immune responses are more complex, involving phagocytosis of invading microorganisms or encapsulation of larger parasites.
Nevertheless, for technological reasons, such as the encapsulation of larger DXM and SPION quantities, we preferred the 10-μm microparticles for further experimentation and future clinical application.
Effector mechanisms include the release of antimicrobial molecules, phagocytosis, the clotting system, the encapsulation of larger objects, the formation of nodules, which sequester smaller intruders and the activation of the melanization cascade (Davis and Engström, 2012; Kounatidis and Ligoxygakis, 2012; Lemaitre and Hoffmann, 2007; Theopold et al., 2014).
Ultraviolet spectrum analysis showed that the largest loading efficiency and encapsulation efficiency could be 8.55% and 94.01%, respectively.
We believe that this process also allows a large amount of ODN encapsulation due to the localization of the negatively charged polymeric DNA on the microsponge surfaces, which facilitates polycation complexation of nucleic acids at higher concentrations relative to solution complexation.
The former involves the action of haemocytes in phagocytosis of microbes, encapsulation of large pathogens and nodule formation [ 1] whereas the latter involves activation of prophenoloxidase cascade leading to melanisation of invading microorganisms [ 2] and synthesis of a battery of anti-microbial peptides [ 3].
