Significance Lectins are endogenous sugar receptors involved in diverse physiological and disease-associated processes. The functional consequences of naturally occurring single-nucleotide polymorphism and alternative splicing in lectins has been explored using glycodendrimersomes, a versatile test system with programmable glycan (complex carbohydrates) display. Importantly, glycodendrimersomes facilitate quantitative determination of lectin-mediated cross-linking, a hallmark of their activity. Threshold and kinetic effects measured for a human galectin associated with autoimmune disease document the sensitivity of the test system and highlight its potential as a new and highly versatile supramolecular sensor for biomedical applications.
