Benjamin Samelson-Jones

His project aims to directly address current limitations of hemophilia A gene and protein therapy by the identification and characterization of new hyperactive factor VIII variants based on his previous studies of hyperactive factor IX variants. He will take a rational approach to identify such variants focused on amino acid substitutions that can enhance factor VIII cofactor activity while maintaining physiological regulation, which will facilitate their translation into therapeutics. In vivo murine studies of efficacy and immunogenicity will provide the basis for subsequent translational studies.

Ze Zheng

Dr. Ze Zheng is an Assistant Professor at the Medical College of Wisconsin and an Assistant Investigator at the Versiti Blood Research Institute (Blood Center of Wisconsin). She received her MBBS in Clinical Medicine from Jiamusi University in China, and her PhD in Molecular Medicine and Genetics, focusing on liver metabolism, from Wayne State University in Michigan. During her postdoctoral training in Dr. Ira Tabas lab at Columbia University, she found a novel source and regulation of basal plasma tissue-type plasminogen activator (tPA) derived from hepatocytes, which is important for fibrinolysis when a vessel injury occurs. Dr. Zheng recently joined the Medical College of Wisconsin in July 2020 and established her research laboratory in the Versiti Blood Research Institute with access to state-of-the-art facilities and group meetings with established investigators in hemostasis and bleeding disorders. Dr. Zheng has been the recipient of a Berrie Scholar Award, an ASH Scholar Award, an AHA Career Development Award, and a Cullen Run COVID-19 Rapid Response Grant. 

As the 2020 recipient of the NHF Career Development Award, Dr. Zheng will be studying the mechanism of increased fibrinolysis in severe hemophilia patients in collaboration with the Comprehensive Center for Bleeding Disorders at Versiti Blood Center of Wisconsin. This work will explore novel therapeutic strategies to reduce basal fibrinolysis and bleeding symptoms in severe hemophilia patients.

Sean Quinn, PhD

Dr. Sean Quinn is a postdoctoral fellow at the Children’s Hospital of Philadelphia in the laboratory of Dr. Rodney Camire. Dr. Quinn received his doctoral degree in Biochemistry/Biophysics from Rensselaer Polytechnic Institute in 2019. For his JGP project, Dr. Quinn will develop novel monoclonal antibodies (mAbs) that bind and protect FV or activated FV (FVa) to promote coagulation in the context of hemophilia. To accomplish this goal, Dr. Quinn will use biochemical and biophysical approaches to map the epitopes where lead candidate mAbs bind to FV/FVa. Moreover, he plans to assess the efficacy of these mAbs using a combination of in vivo approaches with an already established hemophilia mouse model. Long-term, Dr. Quinn’s goal is to become an independent investigator to develop approaches to modulate anticoagulant pathways to treat bleeding.

Yuan Zhang, PhD

Dr. Yuan Zhang obtained her Ph.D in microbiology from Wuhan University, China, in 2015. Her Ph.D work focused on creating new or more effective genetically engineered vaccines against human viruses. In 2016, she joined Dr. Bin Zhang’s group as a postdoctoral fellow at the Lerner Research Institute, Cleveland Clinic. She works on understanding the mechanism of receptor-mediated ER-Golgi transport of secreted glycoproteins. In her JGP project, she aims to identify B domain signals that direct FVIII into the LMAN1-MCFD2 secretory pathway, and investigate the importance of the B domain in FVIII biosynthesis and LMAN1-MCFD2 mediated secretion in mouse models. She hopes that her research will provide important information for guiding recombinant FVIII production and the design of hemophilia A gene therapies.

I am currently working as a Postdoctoral Research Associate at the University of Texas Health Science Center at Tyler, Tyler, Texas, under the mentorship of Professor L. Vijaya Mohan Rao. My research focuses on elucidating novel mechanisms by which FVIIa provides hemostatic and anti-inflammatory effects and the relevance of these mechanisms in treating bleeding disorders and hemophilic arthropathy. I graduated from the University of Calcutta, India, in 2009 with a bachelor’s degree in Microbiology. My post-graduation was also in Microbiology from India in 2011. I completed my doctoral studies in 2019 from the Indian Association for the Cultivation of Science, India, where I focused on understanding the mechanistic details of tissue factor-factor VIIa-induced progression of human breast cancer. I published several peer-reviewed articles from my Ph.D. thesis work in journals, such as Journal of Biological Chemistry, Cellular Signaling, and Molecular Carcinogenesis. I enjoy playing video games, reading novels, and cooking various Indian foods.

Dr. Xuejie Chen is a postdoctoral fellow in the laboratory of Dr. Darrel Stafford at the University of North Carolina at Chapel Hill. Before joining Dr. Stafford’s lab, she received her Ph.D. degree in Cell Biology from Beijing Normal University, P. R. China. In her JGP Fellowship project, Dr. Chen aims to study the contributions of extravascular factor IX (FIX) to blood coagulation and to search for FIX variants that could efficiently displace the endogenous dysfunctional FIX in hemophilia B patients. To achieve this goal, Dr. Chen will study the binding between FIX and the subendothelial basement membranes, mainly type IV collagen, and use the site-directed random mutagenesis library to screen for tighter binding FIX molecules. In doing so, she hopes to identify a FIX variant that can be used in hemophilia B patients for better coagulation therapies.

Author(s):
Kathaleen Schnur
A survey link will be distributed to all hemophilia treatment center social workers with the ask that they forward on to the various staff members at their center. Social workers and other staff will have separate surveys. The questions will be built to be asked in a cascading manner, one question at a time, with the goal of better understanding perceptions of the social work role . Additionally, the social worker will be asked to provide some demographic information to build from prior surveys within the literature. The data collected will be used to create a standards of practice of the social work role and ultimately improve patient care and interdisciplinary collaboration. The standards of practice is intended to capture all the things a social worker is capable of doing within the center. The intent is that this tool will be adaptable based on center size, setting, and layout.
