, 1994) and (2) a convex hydrophobic surface comprised of a cluster of CDR H2/H3 residues (Fig.?3D). The V1V2 structure, in the context of a scaffold and mAb PG9, folds as four anti-parallel beta strands according to recently published data (McLellan et al., 2011) and is similar to the bridging Oxygenase sheet region targeted by anti-CD4i antibodies. The majority of anti-CD4i mAbs are encoded by the VH1-69 gene (Gorny et al., 2009?and?Huang et al., 2004) and two of these mAbs, 412d and 17b, have been compared with mAb 697 (Supplementary Figs. 3 and 4). The amino acid sequence of 697 CDR H2 is highly homologous with the corresponding domain of 412d buy Etoposide and 17b and, like these anti-CD4i mAbs, its hydrophobic residues may play a similar role in its interaction with the V2 epitope consistent with the ODA prediction (Kwong et al., 1998) (Supplementary Fig. 4). Structural alignments of the CDRs H1 and H2 backbones of the 697 heavy chain (excluding CDR H3) with that of 412d and 17b showed a pairwise root mean square deviation (RMSD) of 1.02?? and 0.67??, respectively, which indicate a close superimposition, while light chain L1 and L2 show an RMSD of 1.4?? and 1.7??, respectively, as they are encoded by different VL genes. Generally the antigen binding sites of the three Fabs have similar backbone conformations except CDR H3 (Supplementary Fig. 3). Furthermore, since both 412d and 17b mAbs bind to one side of a four stranded bridging sheet (Supplementary Fig. 5), mAb 697 may use a similar binding mode consistent with its relatively flat antigen binding surface (Fig.?3B). The anti-V2 mAbs were tested for their ability to neutralize a panel of 41 cloned pseudoviruses (psVs) using the TZM-bl cell assay. The panel included 15 neutralization-sensitive Tier 1 psVs (subtype A, AG, B, and C), 22 moderately resistant Tier 2 psVs (subtypes B and C) and four resistant Tier 3 psVs (subtype B) (Table?4) (Seaman et al., 2010). Generally, the neutralizing activity of V2 mAbs is weak and limited to neutralization-sensitive psVs. Only four to eight Tier 1 psVs of 41 tested were neutralized by V2 mAbs with the exception of mAb 2297 which JAK inhibitor showed no neutralizing activity. The IC50 values which express the concentration (��g/ml) of mAb needed to achieve 50% neutralization showed a broad range between
