Adenovirus-mediated in vivo gene transfer and expression in normal rat pancreas.
Gene transfer into the pancreas would be useful for the treatment of a variety of disorders, including cystic fibrosis, diabetes, cancer, and immunomodulation of pancreatic allografts. A hypothesis that various cell populations in the pancreas could be targeted by recombinant adenoviruses was developed and tested. Gene transfer into the rat ductal epithelium, acinar cells, and islets of Langerhans was accomplished with a recombinant adenovirus containing bacterial beta-galactosidase by retrograde delivery of adenovirus into the pancreaticobiliary duct. Maximal gene expression was observed at 3 days and correlated with DNA blot analysis. Histologic analysis of sections from pancreatic tissue in the adenovirus-treated rats demonstrated severe pancreatitis. Immunophenotyping of the inflammatory infiltrate with rat lymphocyte-specific markers showed CD45-, CD8-, and CD4-positive cells. Tissue injury resolved as gene expression was lost, with both features absent by 21 days. Pancreatic regeneration was documented by the presence of 5-bromo-2'-deoxyuridine-positive staining cells. Pancreatic gene transfer with first-generation recombinant adenoviruses can be accomplished by techniques applicable to clinical situations. The use of first-generation recombinant adenoviruses for pancreas-directed gene transfer is limited by the development of inflammation and transient expression.
