Novel and Promising Strategies for Therapy of Post-Transplant Chronic GVHD.

Despite the achievements that have increased viability after the transplantation of allogeneic hematopoietic stem cells (aHSCT), chronic graft-versus-host disease (cGVHD) remains the main cause of late complications and post-transplant deaths. At the moment, therapy alternatives demonstrate limited effectiveness in steroid-refractory illness; in addition, we have no reliable data on the mechanism of this condition. The lack of drugs of choice for the treatment of GVHD underscores the significance of the design of new therapies.

Purification of antibody heteropolymers using hydrophobic interaction chromatography.

A heteropolymer (HP) is a unique dual antibody conjugate composed of specific, chemically cross-linked monoclonal antibodies (mAbs). In this study we have demonstrated that HPs can be purified using hydrophobic interaction chromatography (HIC). Two propyl HIC resins; [PolyPropyl A and EMD Fractogel Propyl (S)] were evaluated in this study.
