Marion Lanteri, PhD

MARION LANTERI, PHD

Director Scientific Affairs, Cerus Corporation, Concord CA USA
Affiliate Investigator, Vitalant Research Institute, San Francisco CA USA
Assistant Adjunct Professor, University of California San Francisco CA USA

With more than 16 years of training in basic science, Marion Lanteri Ph.D. acquired expertise in virology and molecular/cell biology during her Ph.D. training in France while working on glycan modifications in a context of HIV infection. Dr. Lanteri was a lecturer in immunology and virology (specializing in HIV and emerging pathogens) for students attending the Master’s degree program of biochemistry from the University of Nice-Sophia Antipolis, France.

She gained expertise in human immunology during her post-doctoral training at Vitalant Research Institute (formerly named Blood System Research Institute) while working on T cell responses to West Nile virus (WNV) in blood donors. After her post-doctoral fellowship, her primary research focus remained WNV and extended to dengue virus (DENV) infection in humans. As a Co-Investigator and the Project Manager for the multi-center study titled “Viral/Immune parameters of Dengue and WNV in donors: blood safety implications”, Dr. Lanteri helped build repositories of biospecimens collected from longitudinal cohorts of WNV+ and DENV+ blood donors and characterized for immune and viral parameters, in order to inform the WNV and DENV screening guidelines.

Comparing the dynamics of immune and viral parameters in asymptomatic and symptomatic blood donors infected with WNV or DENV, Dr. Lanteri characterized the immune profiles associated with asymptomatic versus symptomatic disease outcomes as well as with viral persistence. Dr. Lanteri was also trained by Dr. Bernard in using the murine model and together they evaluated the remaining risk of WNV transfusion-transmission using the murine model to complement our studies of blood donors. Dr. Lanteri is also interested in using the OMICS approach to identify predictive markers of disease outcome and new therapeutic targets.

Dr. Lanteri played the role of Study Coordinator for several multi-center studies including the Central Laboratory portion of the “Recipient Epidemiology and Donor Evaluation Study (REDS)-III” supported by the NHLBI and as one of the REDS-III investigators, she has led several REDS-III studies addressing a variety of questions on the safety of blood donations and transfusions from both the donor and the recipient points of view.   

Dr. Lanteri now serves as Director Scientific Affairs at Cerus Corporation while remaining an Affiliate Investigator at VRI, participating in ongoing research with the REDS-III group of investigators on: i) Zika virus persistence using samples collected longitudinally from ZIKV-infected donors and ii) the red blood cell storage lesion through the RBC-Omics project.

Eric Delwart, PhD

ERIC DELWART, PHD

Senior Investigator, Molecular Virology, Vitalant Research Institute, San Francisco, CA

Eric Delwart, PhD, is a senior investigator at the Vitalant Research Institute and adjunct professor in laboratory medicine at UCSF. He earned his undergraduate degree in biochemistry and genetics at Newcastle University in the UK and his MSc in molecular biology at the University of Geneva in Switzerland. He was then a research assistant at Genentech in South San Francisco before completing his PhD from the University of Wisconsin at Madison. He was a post-doc at Stanford University and assistant professor at NYU and Rockefeller University before joining VRI.

Research Interests:

Viral discovery is performed on human, animals, biologics, and environmental samples using viral particle enrichment, random nucleic acid amplification, and deep sequencing followed by bioinformatics analysis for the presence of viral sequences. Through local, national, and international collaborations, biological samples from humans and mammals with unexplained symptoms of possible infectious origins are analyzed for the presence of known and new viruses.
Viral discovery was initiated at the Research Institute in 2004 with the characterization of a previously unknown human parvovirus commonly found in the blood of people with blood exposure, such as injection drug users and hemophiliacs. We have since sequenced numerous genomes of human, animal, insect or unknown cellular origin. Following genome characterization and phylogenetic analysis, our goals are to measure viral prevalence, diversity, and pathogenicity. The Research Institute is equipped with an Illumina MiSeq and a high-performance computing platform for bioinformatics analyses, an example of which can be seen here.

Many human and animal diseases of likely infectious origin remain unexplained. Such diseases may be caused or aggravated by viruses for which genomes have not yet been characterized. Sequencing potential viral pathogen genomes provides the starting information required for studies to determine whether these viruses are associated with unexplained diseases using PCR, in situ hybridization, antibody staining and/or serology.

The complex viromes of different human as well as wild and domesticated animal populations are also characterized to allow future changes associated with disease outbreak to be rapidly identified.

A better definition of the many viruses circulating in different animal species will also help rapidly identify the origin of viral outbreaks from cross-species transmissions.

Her current research is focusing on alloimmunization and tolerance induced by chronic erythrocytapheresis. She is an investigator in the NHLBI/NIH REDS-III transfusion safety and retrovirus donor program with a focus in Brazil and Tanzania. With Dr. Michael Busch (PrincipaI Investigator), Dr. Kelly is investigating the influence of sickle cell disease on HIV. She is performing in vitro experiments to determine if peripheral blood mononuclear cells (PBMC) collected from sickle cell disease (SCD) are less susceptible to HIV infection than PBMC collected from age, gender and race matched controls. Dr. Kelly is also Assistant Medical Director at Vitalant (formerly named Blood Centers of the Pacific), the Bay Area’s nonprofit blood service provider.

Research Interests:

  • Transfusion outcomes in children with hematologic/oncologic disorders
  • Alloimmunization in sickle cell anemia
  • Impact of erythrocytapheresis in sickle cell anemia
Establishing a Brazilian Sickle Cell Disease Cohort and Identifying Molecular Determinants of Response to Transfusions and Genetic Determinants of Alloimmunization

This project will develop a centralized electronic database of clinical, laboratory and transfusion information as well as a biospecimen repository for a cohort of ~7,000 sickle cell patients in Brazil.  Planned initial studies from this cohort include characterization of the immune modulation that occurs with transfusion and identification of single nucleotide polymorphisms that contribute to the risk of red blood cell alloimmunization in sickle cell anemia patients.

Gene Expression Profiles in Sickle Cell Disease

In order to characterize gene expression patterns in pediatric sickle cell patients, mRNA expression was quantified for patients at baseline, during crisis and post red blood cell transfusion. Evaluation of differential gene expression patterns in these clinical scenarios may further characterize the central pathways involved in sickle cell pathophysiology as well as those pathways impacted by transfusion therapy.

Alloimmunization of Pediatric Sickle Cell Patients on a Chronic Transfusion Program: Impact of Erythrocytapheresis

The alloimmunization rates of pediatric sickle cell patients in chronic transfusion programs were examined to determine differences in rates of antibody formation between patients on simple and exchange programs.

Nareg Roubinian, MD, MPHTM, is a clinical investigator with appointments at the Research Institute, the Kaiser Permanente Division of Research, and the University of California, San Francisco (UCSF). Dr. Roubinian received his BS from the University of California, Berkeley and his MD from the University of Vermont College of Medicine. He completed his residency in internal medicine at Washington University in St. Louis, and his fellowship in pulmonary and critical care medicine at UCSF.

Research Interests:

Pulmonary Transfusion Reactions
Pulmonary transfusion reactions are important complications of blood transfusions yet differentiating these clinical syndromes remains diagnostically challenging. Within the NHLBI-funded Recipient Epidemiology Donor Evaluation Study-III (REDS-III), I helped lead the Severe Transfusion Reactions Including Pulmonary Edema (STRIPE) study of pulmonary transfusion reactions, such as transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO). As part of STRIPE and parallel studies including TRALI SCCOR, we have been examining the role of laboratory biomarkers in identifying individuals at highest risk of developing a transfusion-related pulmonary complication with the goal of improving the specificity of definitions of these clinical syndromes.

Clinical Outcomes of Blood Transfusion
Our work with the Kaiser Permanente Northern California Division of Research has been relevant to the understanding of clinical transfusion practice. The integrated and granular nature of this study setting has also provided the opportunity to study the impact of blood conservation and associated anemia on resource utilization and subsequent hospitalization. We have utilized the expertise in our collaboration to improve methodology of observational data in transfusion medicine and to develop tools to predict blood utilization using readily available discharge data and to help inform evidence-based guidelines for RBC transfusion.

LARRY J. DUMONT, M.B.A., PH.D.

Larry J. Dumont, M.B.A., Ph.D. is the Director and Senior Investigator at the Vitalant Research Institute at its campus extension in Denver, Colorado. He is Adjunct Associate Professor at the Geisel School of Medicine at Dartmouth. Dr. Dumont spent 27 years at GAMBRO BCT and 10 years at Dartmouth. He received his BS at Regis College, MBA at University of Phoenix and PhD in Clinical Sciences from the University of Colorado. He is the immediate past Chair of the Biomedical Excellence for Safer Transfusion Collaborative (BEST). His current interests are in platelet and red blood cell physiology, cryopreservation of platelets, in vivo cell survival kinetics, and clinical outcomes in transfusion medicine. Dr. Dumont has been an invited speaker at FDA advisory meetings and various national and international congresses.

 

Research Interests:

The Dumont laboratory has historically focused on evaluation of new products for the preparation and delivery of blood products to patients. Evaluations include in vitro characterization, design and execution of early clinical trials, and participation in pivotal trials for regulatory approvals. Now at VRI-Denver, the laboratory is on the way to becoming the leading institute for research and translational development of new, modified, and novel blood components for the transfusion medicine community. Our leading project is development of DMSO cryopreserved platelets. We are also interested in gaining deeper understandings of the biology and physiology of the platelet and red blood count (RBC), relating in vitro measures such as metabolic profiles to in vivo outcomes, and identifying potential targets for processing interventions.

Pulmonary Cryopreservation of Platelets
Platelets for transfusion are stored at 22°C with a 5 – 7 day shelf life. This often severely limits availability in remote care locations and even in large urban areas. Our program, supported through the Department of Defense, has developed cGMP manufacturing processes for the preparation, storage, and distribution of a 6% DMSO, no-wash, cryopreserved platelet (CPP). We continue to characterize the in vitro properties of the CPP and support all clinical trials in the United States.

Platelet and Red Blood Cell Biology and Physiology
Characterization and understanding the biology and physiology of platelets and RBCs will assist in the development of new methods of collection, treatment, storage and delivery for these products. This understanding may also inform the in vivo effects once transfused in terms of safety and efficacy. Work in this area has included describing the metabolic response of cells under various conditions and donor associations with cell phenotypes, and evaluating new methods and procedures.
