| abstract |
A therapeutic reagent to control one or more reactions of the immune system in a host, or to deliver anti-tumour agents, or disease treatment agents to the host. The therapeutic reagent comprises a regulatory moiety and a carrier protein that inactivates or substantially reduces the activity of the regulatory moiety. Also, the therapeutic reagent includes a cleavage site at which cleavage of the therapeutic reagent can occur to free the regulatory moiety from the carrier protein so that the therapeutic reagent can act at a diseased site in the host. |
