The curious case of anti-PEG antibodies

Key Points

• Human exposure to PEG can lead to the formation of anti-PEG antibodies, highlighting an important immunological response.
• Research indicates that multiple exposures to PEG increase the likelihood of developing anti-PEG antibodies.
• Increased understanding of anti-PEG antibodies may influence therapeutic strategies involving PEGylated drugs.
• The presence of anti-PEG antibodies can affect the efficacy and safety of PEG-based therapies, underlining their clinical significance.
