Adenovirus vectors (Ad) have been frequently used for cancer gene therapy research because of their high gene transduction efficiency. However, systemic administration of conventional Ad can lead to the acute accumulation of virus particles and transgene expression in the liver, which may cause severe hepatotoxicity. For these reasons, clinical application of Ad for systemic administration has ...
The use of polyethylene glycols (PEG) is widespread in the pharmaceutical industry as a method to improve the pharmacokinetic qualities of protein and peptide therapeutics. However, such modifications also increase the heterogeneity of protein structures and generate difficulties in purifying such modified species away from the native protein. As PEGylation exhibits the majority of its effect o...
Today, cell therapy is known as an important tool in the treatment of chronic diseases where cells lose their normal function. Immunoisolation systems using microencapsulation or PEGylation have been developed to evade the problem of rejection by the immune system. The aim of the present study was to investigate a combination of microencapsulation and PEGylation methods in coating mouse embryon...
Cellular response of inorganic nanoparticles (NPs) is strongly dependent on their surface chemistry. By taking advantage of robust single-particle fluorescence and giant Raman enhancements of unique polycrystalline silver NPs (AgNPs), we quantitatively investigated effects of two well-known surface chemistries, passive PEGylation and active c-RGD peptide conjugation, on in vitro behaviors of Ag...
