Abstract

Compositions and methods for specific binding to the stalk of a polymeric immunoglobulin receptor (pIgR) of a cell with the proviso that the ligand does not substantially bind to secretory component of pIgR under physiological conditions. The ligand may be targeted to, into, or across the cell and may comprise a biologically active composition.
