Science

Which risk increases when a pharmaceutical protein's glycosylation pattern is unnaturally altered during molecular manufacturing within engineered cells?

A)Increased aggregation in downstream processing
B)Elevated proteolytic degradation rates
C)Destabilization of protein secondary structure
D)Enhanced immunogenicity in patients

💡 Explanation

When glycosylation is altered, the protein's surface is modified exposing new epitopes because cells recognize altered sugar structures as foreign, triggering immune responses. Therefore enhanced immunogenicity results, rather than aggregation, degradation, or structural changes which require different protein misfolding or enzymatic mechanisms.
