The Level of Anti-Polyethylene Glycol
The presence of anti-polyethylene glycol (PEG) antibodies can limit the clinical efficacy of PEGylated drugs and cause anaphylactic reactions in patients. Monocytes/macrophages are effector cells involved in IgG-mediated passive systemic anaphylaxis. We studied the influence of human blood serum on...

| description | The presence of anti-polyethylene glycol (PEG) antibodies can limit the clinical efficacy of PEGylated drugs and cause anaphylactic reactions in patients. Monocytes/macrophages are effector cells involved in IgG-mediated passive systemic anaphylaxis. We studied the influence of human blood serum on the efficiency of uptake of PEGylated nanoparticles by human blood monocytes. It has been shown that magnetic nanoparticles modified with PEG-3000 and solid lipid nanoparticles containing PEG-2000 are avidly internalized by human blood monocytes in vitro, the uptake efficiency depends on the features (composition) of donor blood serum, but does not correlate with the level of the IgG antibody against PEG. Key Words: monocytes; polyethylene glycol; anti-PEG IgG antibody; magnetic nanoparticles; solid lipid nanoparticles |
