Complement inhibitory therapeutics and xenotransplantation.

Once complement-mediated HAR has been inhibited, the full spectrum of cellular and antibody-mediated inflammatory and immune responses characteristic of acute and chronic rejection will need to be counter-manded. But the fact remains that if xenotransplantation is to become a clinical reality, a clinically relevant means of inhibiting complement activation will be required. Soluble complement receptor type 1 provides such a therapeutic option and an option where the dosing regimen is under the control of the physician and can be adjusted in response to the needs of the patient.
