Targeted PEGylated liposomes could increase the amount of drugs or radionuclides delivered to tumor cells. They show favorable stability and pharmacokinetics, but steric hindrance of the PEG chains can block the binding of the targeting moiety. Here, specific interactions between an antihapten antibody (clone 734, specific for the DTPA-indium complex) and DTPA-indium-tagged liposomes were chara...

PAPER V. Gubala et al. Controlling colloidal stability of silica nanoparticles during bioconjugation reactions with proteins and improving their longer-term stability, handling and storage Despite the potential of antibody-coated nanoparticles (Ab-NPs) in many biological applications, there are very few successful, commercially available examples in which the carefully engineered nanomaterial h...

PEGylated sequence-controlled macromolecules using supramolecular binding motifs effectively disrupt Taspase1 interaction with Importin α in a concentration-dependent manner, thereby exploiting novel inhibition mechanism for this protease.

background rapid virological response (rvr) strongly predicts sustained virological response (svr) in patients with chronic hepatitis c (chc), and abbreviates antiviral therapy in some patients. objectives to identify factors predicting virological relapse (vr) in chc patients who attained rvr. patients and methods medical records of 133 chc patients with an rvr after completing 24 weeks of ant...

Dual therapy with pegylated interferon and ribavirin is recommended for patients with chronic hepatitis C virus infection who meet criteria for treatment, but it is unclear whether pegylated interferon alfa-2a or pegylated interferon alfa-2b is more effective or associated with fewer adverse events. Because data from head-to-head trials of pegylated interferon regimens are sparse, we performed ...

Repeated injection of polyethyleneglycol-modified (PEGylated) liposomes causes a rapid clearance of them from the bloodstream, this phenomenon is called accelerated blood clearance (ABC). In the present study, we focused on the immune system responsible for the ABC phenomenon. PEGylated liposomes were preadministered to BALB/c mice and [(3)H]-labeled ones were then administered to them 3 days a...

A sterically stabilized paclitaxel-loaded liposome tailored to target human breast cancer cells was developed, thereby promoting the efficiency of intracellular delivery of paclitaxel through receptor-mediated endocytosis. Results indicated that the targeting moiety (thiolated Herceptin) was successfully coupled to the distal reactive maleimide terminus of the poly (ethylene glycol)-phospholipi...
