Abstract
Disclosed herein are novel methods and compositions for targeting drug delivery systems to specific cells. One aspect relates to a drug delivery system comprising an elastin-like peptide (ELP) component and a ligand selected from the group consisting of an polymeric immunoglobulin receptor binding site in the Cα3 domain of dimeric human IgA (mIgA) and knob capable of either drug encapsulation or drug attachment. Further aspects relate to drug delivery systems comprising an elastin-like peptide (ELP) component and a ligand; wherein the ligand specifically binds to a receptor selected from the group consisting of coxsackievirus and adenovirus receptor (CAR) and polymeric immunoglobulin receptor (pIgR). Further aspects include the novel transcytosing properties of the elastin-like peptide and the ligand, knob. Also provided are methods and pharmaceutical compositions comprising the disclosed therapeutics.
