ABSTRACT:
Targeting molecules for use in delivering biological agents to epithelial tissue are disclosed. Upon delivery, the biological agent(s) may remain within an epithelial cell or may undergo transepithelial transport via transcytosis. The targeting molecules may be used, for example, for the delivery of therapeutic agents.
