Approved drug Immunopharmacology Ligand
alefacept is an approved drug (FDA (2003))
Comment: This is a fusion protein of the CD2 ligand (CD58/LFA3, lymphocyte function associated antigen 3) linked to the Fc domain of IgG1. The construct is called LFA3TIP in [2].
Bioactivity Comments
The Miller et al. (1993) article does not provide a calculated IC50 value for LFA3TIP's inhibition of the CD2/LFA-3 interaction [2]. The inhibition is assessed by measuring rosetting of Jurkat/human red blood cells (with an approximate IC50 of 1-5μg/ml of protein from graphical data in Figure 3a), or by measuring inhibition of induced T cell proliferation (with LFA3TIP inhibition at approximately 86%) [2].
