On the cover: Model of cell penetrating STAT-6 binding peptide (STAT-6-IP) in which the HIV-TAT-derived PTD4 protein transduction domain was fused to seven amino acids surrounding the phosphotyrosine residue of STAT-6. The peptide phosphotyrosine residue (blue), predicted to bind to phosphorylated STAT-6, is oriented to the top. The model was generated using HyperChem 8.0 software. McCusker, C. T., Y. Wang, J.
