AUSTIN, Texas, Mar 17, 2021 (SEND2PRESS NEWSWIRE) — Pure Transplant Solutions, LLC (PTS), a collaboration driven biotechnology company focused on the development of human leukocyte antigen (HLA)-based diagnostics and therapeutics within the field of transplantation, is proud to announce that it has entered into a collaboration agreement with Northwestern University, a world leader in HLA DQ antigen research.

The focus of the collaboration is to develop and test novel HLA reagents created by PTS that may be used for enhanced analysis and characterization of DQ antigens, an HLA Class II type that is increasingly gaining importance in causing rejection in transplant patients.

The research is being led by Dr. Anat Tambur, Director of the Transplant Immunology Laboratory and Comprehensive Transplant Center at Northwestern University Feinberg School of Medicine, and Dr. Rico Buchli, VP of Products and Services at PTS.

“The Tambur lab at the Comprehensive Transplant Center, Northwestern University, Chicago, is focusing on understanding the immunogenicity of HLA-DQ antigens and its role in antibody-mediated rejection in solid organ transplantation,” said Dr. Tambur. “Increasing evidence has demonstrated that DQ mismatches between transplant recipient and donor are the most common to induce de novo donor-specific antibodies (DSA). HLA-DQ antibodies are likely also the most detrimental to graft survival. Understanding the unique structural and molecular properties that make the HLA-DQ molecule so pathogenic may eventually help us better predict which mismatches will induce harmful antibody formation, and which are more permissible. This work requires availability of purified HLA-DQ and other HLA class II molecules, maintaining high physiologic accuracy of the three-dimensional structure. Our collaboration with Pure Transplant Solutions allows us to develop unique approaches to study the unique involvement of HLA-DQ in transplant immunology.”

“In the last years, we have seen a re-emerging role of HLA-DQ in transplantation medicine with increasing evidence that DQ mismatches between transplant recipient and donor are most detrimental to graft survival,” said Dr. Buchli. “Our panel of highly representative HLA-DQ alleles will help to drive novel research to prevent transplant rejection and to contribute to more insight into DSA responses and we are thrilled to be working with Dr. Tambur, a world leader in this field.”
