    摘要: Prolonged or extended release of bioactive protein is achieved using an affinity-based approach which exploits the specific binding of Src homology 3 (SH3) domain with short proline-rich peptides. Specifically, methylcellulose was modified with SH3-binding peptides (MC-peptide) with either a weak affinity or strong affinity for SH3. Controlled release of chondroitinase ABC (ChABC) is also described.

    摘要: The present invention is directed to non-cytotoxic protein conjugates for inhibition or reduction of exocytic fusion in a nociceptive sensory afferent cell. The protein conjugates comprise: (i) a Targeting Moiety (TM), wherein the TM is an agonist of a receptor present on a nociceptive sensory afferent cell, and wherein the receptor undergoes endocytosis to be incorporated into an endosome within the nociceptive sensory afferent cell; (ii) a non-cytotoxic protease or a fragment thereof, wherein the protease or protease fragment is capable of cleaving a protein of the exocytic fusion apparatus of the nociceptive sensory afferent cell; and (iii) a Translocation Domain, wherein the Translocation Domain translocates the protease or protease fragment from within the endosome, across the endosomal membrane, and into the cytosol of the nociceptive sensory afferent cell wherein the Targeting Moiety is selected from the group consisting of BAM, β-endorphin, bradykinin, substance P, dynorphin and/or nociceptin.
