Transepithelial migration of neutrophils (PMN) is a defining characteristic of active inflammatory states of mucosal surfaces. The process of PMN transepithelial migration, while dependent on the neutrophil beta 2 integrin CD11b/CD18, remains poorly understood. In these studies, we define a monoclonal antibody, C5/D5, raised against epithelial membrane(More)
Analysis of peptide binding to human neutrophils (PMN) using phage display techniques has revealed cell-specific motifs reactive with the PMN surface. Phage libraries displaying either linear 9-mer or cyclic 10-mer and 6-mer peptides were incubated with normal human neutrophils followed by elution of bound phage with low pH (pH 2.2) and non-ionic detergent.(More)
RAV12 is a chimeric antibody that recognizes an N-linked carbohydrate antigen (RAAG12) strongly expressed on multiple solid organ cancers. More than 90% of tumors of colorectal, gastric, and pancreatic origin express RAAG12, and a majority of these tumors exhibit uniform RAAG12 expression. RAV12 exhibits potent cytotoxic activity in vitro against COLO 205(More)
