Interleukin-2 Carbohydrate Recognition Modulates CTLL-2 Cell

Although research on the carbohydrate recognition of IL-2 has a long history, its physiological function has not been clearly determined. Sherblom et al. (11) and Zanetta et al. (12) reported that IL-2 recognizes high-mannose type glycans with five or six mannosyl residues as determined by the plate method. Later, Najjam et al. (13) found that

Animal lectins are diverse in structure, but they usually contain modular carbohydrate-recognition domains (CRDs)1 (1, 2). The C-type CRDs are the largest and most diverse class of CRDs.
