Paragraph starter
Research into plant-based antibody production, such as the work by Tengattini et al. (2025), demonstrates that the glycosylation profile engineered by the plant host system directly impacts the antibody's binding affinity to critical immune receptors like FcγRIIIa. This correlation is vital for assessing the therapeutic potential and developing biosimilars, as variations in glycosylation can lead to significant differences in predicted efficacy, such as Antibody-Dependent Cell-Mediated Cytotoxicity (ADCC).
