ABSTRACT:
Purified synthetic polypeptide ligands comprising a 12-mer L-peptide, D-peptides being the D-form of the 12-mer L-peptides, 12-mer retro-inverted peptides being the retro-inverted form of the 12-mer L-peptide, or fragments and homologues thereof, are disclosed. These ligands are for targeting pharmaceutical agents and carriers comprising such agents to intestinal epithelial tissue, especially Peyer's patch and/or M-Cell tissue. Methods of using the ligands are also disclosed.
